The Battle Arena (often referred to as "BA") is a fighting simulator in the Anti-Idle: The Game. Your avatar fights an unlimited number of enemies, one at a time. The types of enemies that appear depend on the setting your avatar chooses to visit. Your avatar can use equipment acquired in other parts of Anti-Idle or crafted from materials looted from enemies in BA. Your avatar also has its own level, different from your player level, that dictates what special arena abilities are available to it in battle. Your avatar also has basic stats which may be raised using pixels awarded for killing enemies. Kills also raise your player's EXP and coins, and may produce loot drops containing more coins, including green and blue. A special Battle Arena fight is required for Ascension at level 9000+. Overall, Battle Arena is the most complex of Anti-Idle's main features, and typically consumes the majority of time spent by players.

For frequently asked questions about the Battle Arena, see Battle Arena FAQ.


Main article: Battle Arena Statistics

The player has a number of stats that determine how powerful he or she is, viewable by clicking on the Stats button. The 6 major statistics are Attack Power, Defense Power, MaxHP, MaxMP, Accuracy, and Evasion, though there are a number of other statistics as well. The major statistics increase with both the player's level and their Battle Arena rank, which is increased by gaining Arena EXP through the defeating of monsters.


Main article: Battle Arena Skills

Skills grant the player abilities or improve their statistics. They can be improved using skill points, which are earned when a character's Arena Rank increases. Most skills require a minimum rank before they can be learned, meaning that only a small number are available to the player at first, though more become available as the player ranks up.

Buffs and Potions

Main article: Buffs

The player may have one buff at a time. The most common source of buffs is a potion.


Main article: Battle Arena Equipment

The player may equip various items to raise stats and fight monsters. It is possible to craft new equipment to use, enhance it to make it better, and fuse two pieces together to gain stats from both.


Robacon (or Robroccoli in vegetarian mode) is a robot found in Ye Olde Pub that provides attack support when you are fighting monsters, in exchange for bacon (or broccoli). He is available at Rank 40.

Robacon starts at rank 1. Robacon must have a weapon equipped for him to have any effect. His weapon must have a rank requirement no higher than his rank. Unless the weapon is the bacon sword, Robacon must also have bacon (or broccoli) to attack.

If the above conditions are met, Robacon will attempt to attack any monster when it spawns, unless it is an evolving monster or would self-destruct upon being hit. Every attack uses a piece of bacon (or broccoli), unless he has the bacon sword equipped. When he attacks, a large strip of bacon (or broccoli) will cover the middle of the screen if he hits.

Robacon's attack may miss, based on your level penalty, hit chance, and accuracy. Robacon's attack uses your stats to determine damage, and the skill power multiplier, which is applied before defense, critical damage, (non-) boss damage, and mana power, is 0.5 + robaconRank/100 + robaconWeaponAttack/300.

Robacon gains twice the Arena EXP that you do (not accounting for the Rebirth bonus) making its weapon level up twice as quickly as it would if you had it equipped. Robacon will stop earning EXP once his rank is the same as yours.

The only stat on Robacon's weapon that matters is its attack, as detailed above. Additionally, the colored tiered bonuses on his weapon also apply to your character, so long as Robacon has bacon (or broccoli) and a high enough rank to use the weapon.

Robacon cannot enter Smiley Island, as he is unable to figure out the password. This means he cannot enter Tower of DOOOOOOM, either. His bonuses apply in Dark Pyramid and Spooky Crypt, even though he will attack only the first monster in the former and none in the latter.

Invisible Allies

Main article: Invisible Ally

Invisible allies (IA) are monsters that you have tamed to fight alongside you. You gain them as a random drop when killing a rare form of an enemy, or killing an enemy that evolves. When they are equipped, they give you passive bonuses and they have special skills that damage the enemy, give you buffs and loots, and so on.


The Bestiary shows information about all the monsters.

Most areas in the Battle Arena have enemies for you to fight. The majority of these enemies start at the spawn point of the area, around the middle of the screen, and charge at you. A few enemies spawn in other places and/or do not move. Enemies attack physically when they hit you (and then bouce backwards) and some may attack you with ranged attacks as well. Each area has specific enemies that may spawn.

Enemy Features

Underneath the picture of the enemy, you'll see a box that gives information about the enemy. This box gives the name of the enemy and its level (which corresponds roughly to your Anti Idle the Game level - not to your arena rank). It also includes a health bar and displays any negative status effects the enemy is currently under.

Main article: Battle Arena Drop Mechanics

Each enemy has a chance to drop various loot, which can be collected by the player.

Missions and Raids

Missions and Raids are the best experience-yielding activities in the Battle Arena. They vary wildly in difficulty, from Mission Kommander's Mission, which can be done at rank 25, up to the Endless Dungeon, which even Rank 500, Level 9001 players haven't yet reached the bottom of (yes, it does have one, don't let the name fool you).

The Introductory Raids

  • Mission Kommander's Mission
    • Requirement: Rank 25
    • How to reach: Just kill monsters. As you kill them, you acquire points; the number of points you get per kill is based on the color of the enemy's name, as described above in the monsters section.  When you have obtained enough points, an icon will appear in the top left of the arena screen, which you can click to teleport back to the pub to claim your reward  The number of points required increases with each completed mission.
    • Rewards: After completing this mission, the player receives some Insta-Progress, Pixelated Mystery Boxes, increased boosts, arena EXP and Proof of Mission. (Each amount will increase as more missions are completed, Pixelated Mystery Boxes increase by 1 for every 100 missions completed.)  You gain an additional Pixelated Mystery Box for every 10 missions you complete.
  • Dark Pyramid (DP)
    • Requirement: Rank 35
    • How to reach: From Ye Olde Pub, travel right until you hit the Desert. Quickly click the dark hole in the background (Epic Pyramid Battle) and click enter. Move fast; monsters will spawn if you wait to long, until you've clicked the Pyramid entrance (monsters won't spawn when the enter menu is open).
    • Rewards: Very good experience for low-level players, several of the 16 lower rings, and a powerful pair of weapons, the Pyrabow and the Evil Sword. Players who score highly can get large amounts of Superior Crafting Material, Blue and Green Coins, and other goodies. Higher-level and -rank players like to do Dark Pyramid as well, for the copious amounts of Yellow Coins and Pixels players can achieve with Autosteal.
  • Defend Mission (DM)
    • Requirement: Rank 70, a Special Wand
    • How to reach: From Ye Olde Pub, travel right until you hit Triangle Land. Click on the hole on the right side of the screen (Hole of Time) and then click on the upper-most triangle (Year 9001). Move right twice to enter the raid.
    • Reward: This mission is very good for general drops and experience, especially for players who have low rank but high level. Completing it gives you a relatively useless item called an Air Bubble, which temporarily stops drown damage.
  • Prehistoric Mission (PHM)
    • Requirement: Rank 70
    • How to reach: From Ye Olde Pub, travel right until you hit Triangle Land. Click on the hole on the right side of the screen (Hole of Time) and then click on the green thing on the right (Year -Infinity). Click right again to enter the raid.
    • Reward: The Om Nom Nom skill, which allows a player to instantly kill a non-boss monster regardless of its stats, is unlocked and upgraded by the first 30 wins in the Prehistoric Mission. It starts with a recharge of 1 minute, and falls to 30 seconds. Players also unlock Alien weapons and armor in the Crafting menu, which is quite strong but suffers from an expiration date.

The Intermediate Raids

  • The Special Arena (SA)
    • Requirement: Rank 90
    • How to reach: From Ye Olde Pub, travel right to the Advanced Training Zone, and jump out the window. Travel up to reach the Arena.
    • Reward: Large amounts of Experience, and Crystals of Rarity and Ultimate Rarity. You will also get a trophy, with a rank and stats that vary depending on how well you did; its terrible for your personal use, but it makes the best Robacon weapon for a long time.
  • Tower of DOOOOOOM (ToD)
    • Requirement: Rank 160
    • How to reach: From Ye Olde Pub, travel right until you hit the Pirate Ship. Jump out through the broken rails, and then click on the right arrow. Figure out the password (its case-sensitive) to get to Smiley Island. Click on the Tower in the Background.
    • Reward: Crystals of Rarity and Ultimate Rarity, as well as some DOOM weapons and armor, with stats varying based on your score. The gear isn't particularly great.
  • The Corruption
    • Requirement: Level 1000
    • How to reach: When your clock reads XX:15-17 or XX:45-47, you will receive an invitation in the form of a brown envelope in the upper-left hand corner of your screen. Click it to enter the corruption.
    • Reward: Monsters in the Corruption don't drop anything special, but they do give large quantities of experience and other valuable drops.
  • Secret Dungeon (SD)
    • Requirement: Rank 250
    • How to reach: From Ye Olde Pub, travel right until you hit the Binary Battlefield. Click the red pixel in the background (bottom-right area) to get to Pokayman City. Click the dark hole in the background to get to the Secret Dungeon Entrance, then click up to enter.
    • Reward: Everything, really. Secret Dungeon monsters give huge amounts of experience, coins, pixels and crafting material; the non-evolving mobs are always rare, meaning they have sky-high drop rate; and the bosses are guaranteed to drop Crystals of Rarity and Ultimate Rarity. There are 5 unique armor sets acquired in the Secret Dungeon, the most notable of which is CHAOS, one of the top four sets in the game, and the best idling set. There are also several unique weapons, including CHAOS AURA, the best idling weapon in the game when doubled with CHAOS, and the Ultimate Lightning Spear, currently the best weapon in the game overall (though that's only when it's acquired in Hardcore Apocalypse mode, to maximize the Unobtainium bonus). If you complete SD for the first time in a day with a very high score, you will receive a unique enhancer with a strength dependent on your score.

End-Game Raids, or the Growth Raids

All of the monsters in these raids grow stronger with each successive kill.

  • THE MEGABOSS's Revenge (Raid) (MBR)
    • Requirement: Beat the Special Arena
    • How to reach: When your clock reads XX:05, 20, 35, or 50, a blue envelope will appear in the upper-left corner of your screen. Click it to enter MBR.
    • Reward: This is among the best experience sources in the game, if you are strong enough to consistently kill the boss in 1-2 hits. If you manage to kill MBR some multiple of 20 times, you will also get earrings, with a rank of the number of kills + 100--so the minimum rank for MBR earrings is 120. These go all the way up to Rank 500 (kill 400) beyond which you will stop getting more. These earrings are among the best in the game, exceeded only by the Ultimate Earrings (300 ascension temporary points) or perhaps outrageously expensive, heavily enhanced Awesome Earrings. You also get unique enhancers every time your MBR bestiary entry reaches multiples of 300 (armor, level 1), 1000 (weapon, level 1), 1500 (armor, level 5), and 5000 (weapon, level 5). These aren't mutually exclusive, so when you reach a killcount of 15,000 you will get all 4 at once.
  • Spooky Crypt (SC)
    • Requirement: Spooky Crypt Key (you have a .5% chance of getting one every time you throw To-Be-Nerfed Gems in the Pyramid), rank 250
    • How to reach: From Ye Olde Pub, travel right until you hit the Binary Battlefield. Click the red pixel in the background (bottom-right area) to get to Pokayman City. Click the dark hole in the background to get to the Secret Dungeon Entrance, then click right to enter.
    • Reward: Lots of experience, for starters. For your first 200 kills in a day, you get a mystery enhancer identifier; for your first 1000, you get a permanent Immortal Pendant with an Unobtainium bonus of 20. Aside from those two exceptions, you get Accessory Unobtainium Enhancers of increasing strength at every multiple of 200 kills, up to 2400, where you get an Accessory Unobtainium Enhancer Level 10. After that, you will get Accessory Unique Enhancers of increasing strength up to 5 for every 200 kills, and then an endless supply of Accessory Unique Enhancers for every 200 kills.
  • Triangle Hideout (TH)
    • Requirement: Rank 180
    • How to reach: From Ye Olde Pub, travel right to Danger Zone, then click on the pale triangle in the background to get to the Abandoned Lab. Click the dark triangle in the lab to go to Triangle Hideout.
    • Rewards: Lots of experience. For the first 10 kills in a day, you will receive a Mystery Enhancer Identifier; for the next 30 kills (up to 40) you will receive Mystery Armor Enhancers Lv. 10; then you will receive 1 Mystery Weapon Enhancer Lv. 10 at 50 kills. Following that, you get Armor Unique Enhancer Lv. 10s up to 90 kills, and at 100 kills you get a Weapon Unique Enhancer Lv. 10. Every 10 kills after 100 will net you Accessory Unique Enhancer Lv. 10s. Triangles also drop Neon Skins, currently the best skins in the game, with starting defense all the way up to 1050.
  • Endless Dungeon (ED)
    • Requirement: Beat Secret Dungeon
    • How to reach: When the clock reads XX:30, you will get an invitation in the form of a purple envelope in the upper-left corner of the screen. Click it to enter.
    • Rewards: Insane amounts of coins, pixels, crafting material, and experience. The Endless Dungeon lacks the high rare and epic rates of SD, meaning a much lower drop rate, but when you do get a drop it's worth up to 11x the same drop from SD. ED also offers Demon Slayer armor, the best set in the game; it scales with how deep you go, and base pieces can give pre-fusion, pre-enhancement stats of over 900 attack and 9000 defense.
