Season 4 began with a warning: if Ozzaria stayed on Normal Mode, Moon Lord would be dead in ten minutes. The solution was Master Mode. What followed was one of Ozzaria's most developmental early seasons — packed with brutal bosses, griefers, rollbacks, expanding staff, vote rewards and the birth of a real custom economy.
"Moon Lord in 10 Min"
Season 3 disappeared on the morning of 20 March 2022.
A few minutes later, the replacement world began generating.
Oz joined.
OzServer: "It works!"
KDY followed shortly afterwards.
There were immediately problems with permissions.
Commands were missing.
Plugins needed fixing.
The server restarted several times.
In other words, Season 4 was beginning exactly like an Ozzaria season should.
Then another problem became obvious.
The new world was running on Normal Mode.
Fusion V seemed pleased.
Fusion V: "Normal mode epic"
KDY was not.
KDY: "bad"
Then he made a prediction:
KDY: "normal mode = moon lord in 10 min"
Fusion V's response was immediate.
Fusion V: "Also yes"
After Season 2's repeated arguments about rushing progression, this was probably a fair concern.
If Ozzaria's players were given an easier world, there was every possibility that they would tear through it.
So Season 4 went in the opposite direction.
Later that day, the world information confirmed the new challenge:
Difficulty: Master.
Season 4 had become Ozzaria's first clearly recorded Master Mode season.
It was going to take considerably longer than ten minutes.
---
Popular Players of Season 4
Season 4 had one of the largest and most active communities Ozzaria had seen so far.
Several old names remained dominant, while another wave of regular players began becoming part of the server's history.
KDY
Some things apparently never changed.
KDY remained one of the most active people on Ozzaria.
He was still a moderator.
He was still heavily involved in progression.
He was still watching for suspicious players.
And he was still telling people not to rush bosses.
Later in the season, when Italia Troller wanted to continue progressing, KDY reminded him:
KDY: "no rushing bosses italia"
By now this was becoming less of a rule and more of an Ozzaria tradition.
KDY also became one of the earliest users of the new Voter system, eventually displaying a ridiculous combination of ranks representing his history on the server.
By the end of the season, Oz described him as:
"OG, Trusted, Staff, Moderator and Voter combined"
KDY had somehow become a collection of Ozzaria ranks wearing a Terraria character.
Exe
exeexexe the new one remained one of the defining personalities of early Ozzaria.
Season 3 had given Exe the hotel.
Season 4 increasingly turned him into a builder, tester and walking bug report.
He held Trusted, became an early Voter, experimented with builds and regularly reported strange behaviour caused by mobile devices or server plugins.
Even his name continued becoming more ridiculous.
At one point it appeared as:
~exexexexeeexexe
Nobody questioned it.
That was simply Exe now.
Jotaro
Season 4 was a breakout season for Jotaro.
Early on, a large percentage of his communication could essentially be summarised as:
"help"
But Jotaro rapidly became one of the season's most recognisable players.
He joined boss fights, traded equipment, experimented with the new economy, earned the Voter rank and became part of the regular group appearing throughout the world.
When Oz later explained the newly created shop to him, Jotaro discovered that he had 19 coins.
Oz's assessment:
OzServer: "You have 19 coins you are rich"
The standards of wealth were still developing.
Drako the Warrior
Drako continued directly from Season 3 and became one of the most useful players in the world.
He worked on pylons.
He prepared arenas.
He helped organise progression.
He protected shared infrastructure and was eventually Trusted.
After the griefing problems of the opening days, Drako was even asked to claim the public crafting room so that it could be protected from other players.
By late Season 4, he was one of the people driving the final push toward the endgame.
Ludaw
Ludaw's role changed significantly during this season.
When Oz was unavailable during another griefing incident, Ludaw was temporarily given Mod Lite so somebody online could actually remove griefers.
The promotion happened so suddenly that Ludaw himself asked:
Ludaw: "How did I get mod?"
He was then given the essentials:
Disable players. Kick players. Stop the server from being destroyed.
Later, Ludaw became deeply involved with farming, progression and the new economy.
By 30 March, he casually announced that he had:
780 coins to spend.
The economy had existed for only a matter of days.
Ludaw had apparently already discovered capitalism.
Mabh, Diamond and Clam
As Season 4 progressed, Mabh, Diamond and Clam became increasingly recognisable regulars.
They traded.
They fought bosses.
They planned farms.
They appeared constantly during the final stages of progression.
Diamond and Clam were particularly visible throughout the Moon Lord period, while Mabh regularly joined them in late-game projects.
When Clam was shown the developing OzEconomy plugin, he responded:
Clam: "You are quite talented"
Then immediately followed it with:
Clam: "Imma break the economy XD"
Oz replied:
OzServer: "Dare you to try"
An excellent relationship between developer and user.
Aurko
Aurko became particularly important during the chaotic opening days.
When a griefer attacked while Oz was asleep, the obvious weakness became staff coverage.
Someone needed to be online when Oz wasn't.
Aurko was active during those hours and was given Mod Lite, becoming another part of the expanding staff system.
He was also one of the first people who had to deal with a different Ozzaria problem:
Sometimes the anti-cheat was almost as dangerous as the hackers.
---
Master Mode
Initially, Master Mode achieved exactly what KDY wanted.
Progression slowed down.
At 2:04 PM on the first day, the boss tracker still said:
No bosses have been defeated in the world so far.
Eventually King Slime and Eye of Cthulhu fell.
Then came Deerclops, Brain of Cthulhu, Queen Bee and Skeletron.
But there was considerably more caution surrounding progression than before.
Wall of Flesh was especially controlled.
On 21 March, Oz warned everyone:
Oz: "Don't kill the WoF"
And then made the consequences extremely clear:
Oz: "If you do I will have to load in a backup"
Imagine defeating a Terraria boss so early that the server owner threatens to reverse time.
Eventually permission was given.
By the evening of 22 March, Wall of Flesh was dead.
Season 4 had entered Hardmode.
And that was when Master Mode began reminding everyone why it was Master Mode.
---
The Griefer Arrives While Oz Is Asleep
Season 4 lasted less than a day before Ozzaria had another major griefing problem.
While Oz was asleep, a player identified in the chat as aqwwa began attacking the world.
According to the players who witnessed it, the griefer first attempted to use bombs on the surface.
That failed.
So they switched to a pickaxe.
When Oz returned, he asked:
Oz: "Was the server griefed too much?"
Aurko's answer:
Aurko: "yes"
Oz considered loading a backup.
But something about the incident was strangely satisfying.
Some protected areas the griefer had attempted to destroy simply could not be damaged.
Oz remarked:
OzServer: "It's actually funny seeing the area they were trying to grief can't be griefed"
Ozzaria's protection systems were starting to work.
Then Oz checked the backups.
And history repeated itself.
OzServer: "There was a backup taken in the exact minute the griefer joined lol"
Again.
In Season 1, Elden had joined almost exactly after a backup.
Now, three seasons later, another griefer had somehow achieved the same thing.
The clean save was loaded.
Oz eventually confirmed:
OzServer: "Alright this is the exact save"
OzServer: "no griefed at all"
The attack had effectively been erased.
---
Staff for When Oz Wasn't There
The aqwwa incident revealed another problem.
Oz had been asleep.
A server could have anti-cheat, backups and protected regions, but somebody still needed to react when things happened.
Fusion V commented that Ozzaria probably needed more moderators.
The staff system began adapting around availability.
Aurko received Mod Lite.
Not long afterwards, another incident happened while Oz was unable to properly deal with it.
This time, Oz turned to Ludaw.
Oz: "Luda I'll give you a temporary mod status so you can remove any griefers because I can't right now"
Seconds later:
Ozzaria: "Account Ludaw has been changed to group modlite!"
Ludaw:
"How did I get mod?"
Season 1 staff had been extremely informal.
By Season 4, the reasoning was becoming clearer.
Ozzaria did not simply need people with ranks.
It needed trusted people who were actually there when something went wrong.
---
The Nine-Hour Rollback
Then came JackIsJesus.
On 22 March, players began discovering more damage.
Ludaw:
"omg someone griefed"
Drako reported that the statue farm had been destroyed.
Other areas had also been damaged.
Players began pointing toward Jack.
When Oz returned, he asked directly whether Jack had been responsible.
Drako confirmed the accusation.
This time, fixing everything manually was not worth it.
Oz made an announcement:
OzServer: "ok loading a backup"
Then came a warning to everybody online:
OzServer: "stuff your inventories so you dont lose anything"
There was one small issue.
The clean backup was from:
exactly nine hours earlier.
Nine hours of world changes were about to disappear.
The server restarted.
Buildings moved backwards through time.
Farms reverted.
Items stored in the world vanished unless players had moved them into their inventories.
And Ludaw was not particularly impressed.
Ludaw: "man this rollback has put me off"
The situation became even worse when players realised the griefing was not Jack's only alleged offence.
Drako reported:
Drako: "Oh, he was also duping"
Oz checked.
The evidence included:
Treasure Bag (Brain of Cthulhu) (999)
Subtle.
Very subtle.
---
Backups Become Infrastructure
Season 1 had taught Ozzaria the value of backups.
Season 4 turned them into routine infrastructure.
Oz explained:
OzServer: "world backups are every 10 mins so dont worry about griefers"
And then added:
OzServer: "database backed up too"
The server was becoming harder to permanently damage.
A griefer might destroy a building.
A hacker might create invalid items.
A player might mine shared infrastructure.
But increasingly, Ozzaria had another option:
erase what happened.
Later in the season, another griefer damaged the world.
Oz eventually confirmed:
OzServer: "All damage was restored from the griefer"
He still did not know who had mined some of the chests.
But the important part was that the world survived.
The battle between Ozzaria and griefers was slowly changing.
The question was no longer always:
"Can we stop somebody from destroying things?"
It was becoming:
"How quickly can we undo it?"
---
The Anti-Cheat Becomes a Little Too Excited
The anti-cheat continued evolving throughout Season 4.
Unfortunately, detecting suspicious behaviour without annoying legitimate players was not easy.
At one point, Aurko discovered that he could not break wires.
Ludaw explained:
Ludaw: "wires is bugged atm"
Then gave everyone some very practical advice:
Ludaw: "dont make or break any wires"
yay responded by mocking Oz's anti-cheat coding.
This was not the only strange interaction.
Players occasionally triggered protections through completely normal Terraria behaviour.
Dynamite caused problems.
Certain world interactions caused problems.
Plugins had to distinguish between a hacker modifying the world and an ordinary player simply doing something unusual.
So Season 4 continued the same development cycle seen since Season 1:
Add protection. Discover false positive. Fix false positive. Discover new exploit. Add more protection.
By 30 March, Oz summarised the state of the server with:
OzServer: "and a heck load of anticheats"
Accurate.
---
"Start Writing a Book lol"
Season 4 also saw another Ozzaria system become much more important:
Voting.
Players could vote for Ozzaria on Terraria server-listing websites.
More votes meant greater visibility for the server.
But asking people to vote was one thing.
Giving them a reason to vote was another.
On 23 March, Oz gave a very long explanation of the system.
Players would enter their in-game username on the voting website.
After voting, they could return to Ozzaria and use:
/reward
Votes could be made once per day.
The server would receive a ranking benefit.
The player would receive rewards.
After Oz finished explaining all of this, somebody replied:
"start writing a book lol"
Four years later, that is now considerably funnier.
Because here we are.
Writing the book.
---
The Voter Rank
The voting system quickly became much more than a few free items.
On 24 March, Oz announced:
Oz: "btw voter rank is soon gonna be a thing"
He then added:
"(actually I might be able to make it possible in the next hour)"
And, remarkably, it basically happened.
Players who had voted could use /reward and receive a special Voter rank.
The rank could stack with existing statuses.
Exe became:
[trustedvoter]
Italia Troller became the first player to have OG and Voter at the same time.
KDY eventually combined Voter with his already ridiculous collection of ranks.
Voting also affected gameplay.
Each successful reward could increase the player's maximum health.
Oz explained to Exe that two votes had increased his health by 20 + 20, bringing him from 460 to 500.
And the bonus was not necessarily limited to Terraria's normal health ceiling.
KDY asked what the maximum health could become with voting.
Oz answered:
OzServer: "it can go forever high"
This had the predictable consequence of creating players with increasingly absurd health totals.
But it worked.
People started voting.
And Ozzaria started climbing.
---
From Trading to an Actual Economy
The earliest seasons had an economy in the loosest possible sense.
Players traded Terraria items.
Platinum changed hands.
The Dumpster redistributed whatever nobody wanted.
Season 4 started creating something much more recognisably Ozzaria.
During the second half of the season, Oz began developing an economy plugin.
At one point he realised what it could eventually support.
Oz: "omg I could make ranks now"
Then:
Oz: "SO MANY POSSIBILITIES WITH ECONOMY"
A few seconds later came the other side of software development:
Oz: "but at the same time overwhelmed a bit"
The first versions were basic.
Players could have balances.
They could transfer money.
The system was tested separately while new features were developed.
Then it moved onto Ozzaria.
By 28 March, Oz announced:
OzServer: "This is the latest version of the OzEconomy plugin"
Clam immediately responded:
Clam: "Imma break the economy XD"
Oz:
"Dare you to try"
The shop system was now being used in-game.
Players could view categories.
Buy items.
Check balances.
Spend their new currency.
When Jotaro discovered he had 19 coins, Oz declared him rich.
Two days later, Ludaw was sitting on 780 coins looking for things to spend them on.
Things had escalated quickly.
---
Ozzaria Starts Becoming Ozzaria
By 30 March, Oz stopped and listed just how much the server had changed.
Ozzaria now had:
- An economy
- Vote rewards
- A custom shop
- The Voter rank
- Special voter icons/emotes
- Account verification
- A growing collection of anti-cheat systems
The commands players were expected to understand were multiplying as well.
/verify
/register
/login
/who
/spawn
/shop
/eco
/vault
/help
By April 1, Oz joked about Exe greeting new players by dumping essentially the entire instruction manual on them at once.
This was a major change from Season 1.
Only a few weeks earlier, Ozzaria was mostly Terraria with a Discord bridge, some ranks and protection plugins.
Now there was a custom economy.
Custom rewards.
Persistent account systems.
Custom shops.
Voting integration.
Staff tooling.
Protected regions.
Automated backups.
Anti-cheat.
Season 4 was one of the first times the server really began separating itself from a normal Terraria world.
---
Master Mode Fights Back
Meanwhile, the actual game was still trying to kill everybody.
Hardmode progression continued.
Queen Slime fell.
The mechanical bosses began.
By 25 March, The Destroyer had been defeated.
Later that day, the tracker included all three:
- The Destroyer
- The Twins
- Skeletron Prime
But Master Mode was becoming controversial.
During one fight, Orion Terra asked:
"how are we supposed to survive this-"
Then:
"why do we do master mode"
His conclusion was simple:
"expert's a good difficulty"
Two minutes later he directly suggested:
"next reset do expert mode, not master"
The complaints continued.
On 27 March, Orion declared:
"This is why Master Mode should only be in singleplayer"
Drako's response:
"Yes"
KDY had successfully prevented Moon Lord from dying in ten minutes.
The cost was apparently everybody's sanity.
---
The March Through Hardmode
Despite the difficulty, progression continued.
By the final week, the defeated list expanded rapidly.
The mechanical bosses were gone.
Then Plantera fell.
Duke Fishron followed.
Empress of Light was defeated.
Golem finally joined the tracker.
Ancient Cultist fell.
The endgame had arrived.
And, somehow, throughout all of this, people were still arguing about rushing.
On 25 March:
Exe: "why u rushin boss?"
Italia Troller answered:
"Oh yeah we need speedrun"
KDY immediately stepped in.
KDY: "no rushing bosses italia"
Season 2 may have ended.
Its greatest argument had not.
---
Moon Lord, Eventually
KDY's original prediction had been:
Normal Mode = Moon Lord in ten minutes.
Season 4 proved Master Mode could delay that slightly.
The first major Moon Lord fights arrived late on 30 March.
At 10:52 PM:
Moon Lord has awoken!
More attempts followed.
At 11:47 PM:
Moon Lord has awoken!
Then again just before midnight.
Players gathered fragments.
Loot began appearing.
KDY showed a Meowmere.
Clam eventually decided there was no reason to stop.
Clam: "Another moon lord"
Then:
Clam: "for the sake of it"
At 11:59 PM:
Moon Lord has awoken!
Diamond returned at exactly the wrong moment.
Diamond: "wrong timing"
Mabh joined about a minute later.
Mabh: "Hey guys"
Diamond gave him an extremely normal greeting:
Diamond: "hi moon lord again btw"
A few minutes later, Clam's review of the fight was:
Clam: "EZ"
The next morning, Oz checked what had happened.
OzServer: "Moonlord DEAD?"
Drako:
"Yep"
Oz:
"pOGg"
By the morning of 31 March, the boss tracker officially included:
Lunar Boss.
Season 4 was complete.
It had taken considerably longer than ten minutes.
---
And Then They Kept Summoning Him
Completing the season did not mean Moon Lord received any peace.
He was summoned repeatedly throughout 31 March.
Again in the afternoon.
Again in the evening.
Again at night.
Again the following morning.
Players farmed loot.
People chased weapons.
Others simply joined fights because they were happening.
At one point a player asked KDY:
"when u gonna kill moonlord?"
This was after the quest tracker already listed Lunar Boss.
The answer to "has Moon Lord been defeated?" was apparently no longer important.
There could always be another Moon Lord.
---
Reset Before the Weekend
By 1 April, attention had shifted toward the next world.
At 8:33 AM, Ludaw asked:
Ludaw: "Hey Oz, can we reset early for the weekend?"
Oz considered it.
OzServer: "Hmm maybe"
There was just one problem.
OzServer: "but I have school in -1 minuts"
Then the realisation:
OzServer: "oh- sht i need to go"
Ludaw:
"ruuunnn"
The reset would have to wait.
For a few hours.
---
"Should I Do a Reset Right Now?"
At 3:29 PM, Oz returned to the question.
Oz: "Should I do a reset right now?"
There were only a small number of players online.
The answer was essentially:
Why not?
So Season 4's reset began.
Naturally, it did not work perfectly on the first attempt.
The server restarted.
Commands were tested.
Something was not behaving correctly.
By 4:05 PM, Oz's patience was disappearing.
Oz: "DUDE"
Then:
Oz: "THIS IS STARTING TO ANNOY ME"
A completely appropriate way for an Ozzaria season to end.
Then, at 4:08 PM, That New Guy checked the boss tracker.
For the first time in nearly two weeks, it responded:
No bosses have been defeated in the world so far.
Ten seconds later:
Oz: "World is reset join!"
Season 4 was gone.
---
"This Is Only the First Day"
Players began entering the new world.
The progression tracker was empty.
Resources had to be collected again.
Bosses had returned.
Another seasonal cycle had started.
And by the end of that very first day, an incredibly familiar argument was already happening.
Players wanted to progress.
That New Guy objected.
That New Guy: "bruh dont rush we cant keep up"
Hours later:
That New Guy: "but dont rush"
Then came a sentence that perfectly echoed KDY at the beginning of Season 2:
That New Guy: "this is only the first day"
Three resets had now occurred.
New systems had been created.
The staff team had grown.
The server had become dramatically more complicated.
But one thing remained constant.
Ozzaria players still needed to be told not to finish Terraria immediately.
Season 5 had begun.
---
Legacy of Season 4
Season 4 began as an attempt to solve one problem:
The players were progressing too quickly.
Master Mode was the answer.
It worked.
Sort of.
Moon Lord survived longer.
Everyone else suffered instead.
But the difficulty itself was only part of what made Season 4 important.
This was a season where Ozzaria's infrastructure expanded enormously.
Regular ten-minute world backups became normal.
Database backups protected player data.
Protected regions became more important after repeated griefing.
Aurko and Ludaw helped expand staff coverage.
The anti-cheat continued becoming more automated.
Voting became a proper reward system.
The Voter rank appeared.
Votes could increase maximum health beyond Terraria's normal limit.
And most importantly:
Ozzaria developed a real custom economy and shop.
That last change represented something much larger.
Season 1's players had traded items with each other.
Season 4's players were starting to interact with systems that existed specifically because they were playing Ozzaria.
Not Terraria.
Not TShock.
Ozzaria.
The server was slowly developing its own progression systems, its own currency, its own rewards and its own identity.
And the community was changing with it.
KDY and Exe remained at the centre of the chaos.
Drako and Ludaw became increasingly important.
Jotaro emerged as one of the season's biggest new regulars.
Mabh, Diamond and Clam became familiar late-season names.
More players meant more builds.
More progression.
More staff.
More systems.
And, naturally...
More griefers.
Season 4 ended on 1 April 2022.
The Master Mode world vanished.
The boss tracker returned to nothing.
The players joined again.
And before the first day was even finished, someone had to say it:
"dont rush"
"this is only the first day"
Some traditions are impossible to reset.
Season 4 was over.
Season 5 had begun.
