Elite crashers

A Nest Keeper and a few Elite Crashers after destroying a Sanctuary in Siege.

The Bosses (aka Visitors) are AI-controlled large entities in Arras.io, that spawn randomly upon certain conditions. There are currently twenty-nine types of Bosses, seven of them being the Elite Crashers, an Elite Skimmer, two Rogue Bosses, four Mysticals, three Nesters, five Celestials, three Rogue Celestials, two Eternals (Ragnarok and Kronos), the Legionary Crasher, and a rare Siege-exclusive boss called Bob. In arms race, there are buffed versions of these bosses (called Delta Crashers and Delta Skimmer) with slightly different names. Also, in non-Siege and non-Arms Race gamemodes, the Elite Skimmer, Rogue Palisade, Summoner, and the Nest Keeper are collectively referred to as "Strange Bosses". The bosses are far stronger than regular tanks and award tens of thousands of XP, sometimes even hundreds of thousands, to the player(s) who deals the final blow upon defeat. Bosses can gain XP like other tanks and polygons, which allows the XP reward to grow much higher than their spawn score.

Technical[]

Stats[]

The Bosses usually have buffed stats, but some of them are nerfed. These are the Bosses’ stats compared with the Basic:

  • FoV: ×1.3 (Hunter ~ Assassin)
  • Speed: ×0.1 ~ 0.15
  • Health: ×1.5 ~ 2
  • Shield: ×1.25 ~ 2
  • Body Damage: ×2.5 ~ 3

Also, all of the bosses have a build of 3/9/2/7/7/5/6/0/6/6. You can use these stats if you want but you wont have enough points for this build since it requires 51 points so you'll have to use this build with operator or in any Growth mode, Old Dreadnoughts and Nexus. It is recommended For growth and Old Dreadnoughts to put any left over points in Speed and for Nexus Bullet Speed, Bullet Health, Bullet Penetration, Bullet Damage or Reload.

In Siege, some Bosses have slightly stronger stats.

Behavior[]

In normal gamemodes, the Bosses spawn at least 10 minutes after the previous Boss is defeated or the server starts; the spawning chance increases as time passes. Shortly before they spawn, a spawn message will be broadcasted, as well as the exact moment they spawn (see Notifications for more info). When a boss is defeated, the message "A visitor has left!" will be displayed to all players in the server. If multiple bosses happen to spawn, they will always be different types/variants of bosses (there can’t be multiple of the same kind). Also, Elite Crashers will never spawn with other types of bosses (for example, "Strange" bosses or Rogue Celestials), as they can only spawn with other Elite Crashers, or just a lone Elite Crasher.

Normal Bosses[]

Elite Crashers[]

Main article: Arras:Elite Crasher

The most common type. They have pink triangular bodies, have seven different types and they look like big Sentries or Crashers. They often spawn in Pentagon Nest outside of Siege.

Name Description Strategy Image
Elite Destroyer This variant has a wide Cannon on each side called “Devastator Cannon”, and an Auto Turret which looks like the Triplet in the center, though the firing pattern differs from the Triplet’s. The Devastator Cannons’ Bullets are bigger and stronger than the Annihilator’s. Also, it spawns normal Crashers. It is weak against bullet spammers that can nullify the boss’s Turret. ECDestroyerVar
Elite Gunner This variant has two Auto Turrets on its front sides. These turrets each have two Gunner cannons. The Gunner Cannons don’t do so much damage but have fast firing rate. This Elite Crasher also has a large launcher that shoots out Pillboxes, much like those used by the Engineer. There is also two short spikes that stick out on the Elite Crasher’s front, as well as another two on its backside. It is weak against tanks with upgraded health to absorb damage from Pillboxes and tanks with high damage output such as the Destroyer. ECGunnerVar
Elite Sprayer This variant mainly uses bullets as it has two Sprayer Auto Turrets on both sides and has a Machine Triple Auto Turret in the middle. This boss can be easily overpowered with a Destroyer-branch or with a team of bullet spammers. Elite Sprayer
Elite Battleship This variant uses three Auto Turrets and nine Swarm Drone Spawners. The positioning of its weapons allows it to swarm tanks while also dealing damage with its auto turrets. Teamwork is recommended to take out this Boss because of its multiple strengths. ECBattleshipVar
Elite Spawner This variant has 3 spawners (one on each side) and they each spawn sentries. This boss also has an auto turret which looks like a twin in the center and fires similar to it. This boss is relatively easy to counter with nearly every tank due to its low defense and damage which also makes it the weakest and easiest boss to fight. Elitespawner-removebg-preview
Elite Trap Guard This variant has 6 auto turrets (two on each side) and 3 trapper auto turrets (one on each side). The Elite Trap Guard is also equipped with 3 barrels and 3 trapper barrels on its center. Multiple players are needed to take one down: its many powerful weapons make it difficult to approach. Its lack of offensive weaponry though, is its weakness, and allows players to out-penetrate with superior firepower. Uncropped Elite Crasher Defender
Elite Spinner This variant is equipped with a total of 9 Gunner-like barrels that are pointed outwards, it uses 3 of them on each of its sides. The Elite Spinner is also equipped with a single Cyclone Turret on its center. Elite Spinner is laughably weak alone and can be soloed by a single high DPS tank. UncroppedEliteCrasherSpinner

Rogue Palisade[]

RoguePalisade
Main article: Arras:Rogue Palisade

The Rogue Palisade has 6 Trap Launchers and 6 Minion Spawners and has a Hexagon body. While the Spawners spawn 12 minions, the spawn rate is sluggish therefore it usually doesn’t get the chance to spawn a lot of drones.

Beware when battling it as even though the drones don’t deal tons of damage, the amount of them and their health prevent you from directly attacking the Rogue Palisade. If you don’t pay attention to these drones, you will be dead in no time.

Elite Skimmer[]

Elite-Skimmer
Main article: Arras:Elite Skimmer

The Elite Skimmer has a triangular body with color of the Triangle, and has a Skimmer Turret on each side that shoots Hyper Missiles. These Hyper Missiles have four cannons arranged similarly to the Fighter but without the front cannon, and travel fairly fast while resisting high damage.

This Boss can easily catch tanks that aren’t careful with their movement, but is weak against larger groups of tanks, especially with more balanced stats or those of glass cannons that can steer clear of its Missiles and their bullets.

Summoner[]

ArrasSummonerNAV
Main article: Arras:Summoner

The Summoner features the Square-like body, and has four Necro Drone Spawners on each side, making it look like the Necromancer.

The drones deal minimal damage, but their large amount can quickly kill tanks, particularly if they cannot easily escape away from it. Some of the crowd-control tanks like Octo Tank or Penta Shot are effectively at minimalizing its threat, and may even quickly defeat it.

Nest Keeper[]

NestKeeper
Main article: Arras:Nest Keeper

The Nest Keeper features five Twin Auto Turrets, one Boomer Auto Turret, and five Drone Spawners. It is the only boss to feature a Pentagon shape, as well as the only tank in the game to feature a Boomer Auto Turret.

Teamwork is almost always needed to kill the tank. The drones which it spawns are very slow, but deal massive amounts of damage, so they must be kept an eye on to them. The Boomer Auto Turret however deals tons of damage and is much faster, as well as the boomerang projectiles being quite resistant on damage as well, making it difficult to damage the Nest Keeper if the turret is focused against the player.

Siege Only Bosses(Except Nest Keeper and Summoner)[]

Rogue Armada[]

Note: Name is unofficial.

RougeArmadacrop1

The Rogue Armada is the only friendly boss in Arras.io and so far only appeared

The Rogue Armada has 7 Shotgun Turrets and 7 Tiny Set Trap Spawners and has a Heptagon body. The Spawners spawn lots of traps, plus both turrets and spawners fire at the same time.

When it spawns, it would be just a normal black Heptagon, but once pushed into a Sanctuary, it becomes a Rogue Armada.

Mysticals[]

Main article:Mysticals

Mysticals are a group of Bosses/Boss type that spawns a massive amount of drones to use as their main ammunition. They are rather weak and are exclusive to the Siege gamemode, aside from the Summoner.
Name Description Image
Sorcerer The Sorcerer appears as an abnormally large Egg with 2 spawners opposite each other, similar to Overseer. They spew out Egg-like drones called cheeseballs. They have extremely low health (similar to the polygon itself) but also have equally horrifying speeds. Similar to the Egg Sanctuary from Woomy-Arras.io. Its drones give a small amount of XP when destroyed. SorcererRender
Summoner The Summoner appears as an abnormally large Square, with 4 spawners, one on each side, similar to the Arras.io version of Necromancer; they rapidly spawn Square drones. The drones are not really fast, however. ArrasSummonerTransparent
Enchantress The Enchantress appears as an abnormally large Triangle, with 3 spawners, one on each side; they spawn Triangle drones at medium speed. EnchantressRender
Exorcistor The Exorcistor appears as an abnormally large Pentagon (about as big as a large-end Beta Pentagon), with 5 spawners, one on each side, similar to that of Pentamancer(only available in Arms Race). They spawn Pentagon drones that move at slow speeds but high damage, and are similar to those of Paladin, a Celestial variant. ExorcistorRender

Nester[]

Main arcticle:Nester

Nesters are bosses in Arras.io, There Are 3 types of Nesters, The Nest Keeper spawns in all Gamemodes while the Nest Warden and Nest Guardian Spawn in Siege. They are much more Powerful than other common bosses, with much more tanky bodies and high damage.
Name Description Image
Nest Keeper The Nest Keeper is a special boss, being the only current one using Boomers. Its Twin auto turrets deal low but continuous damage per turret, and if several are locked onto a single target, expect that target to be screwed, because the drones are hostile to anything sans polygon team. Boomer turret fires very slowly, but the boomerangs deal big damage. Think of it like a sniper. ArrasNestKeeper
Nest Warden The Nest Warden is a mostly defensive boss; it has Constructor launchers on each side. Blocks do not go far, but they are a hazard to any tanks that need free space to operate. The Cruiser auto turrets launch swarm drones which...well, act like swarm drones; low penetration and health, decent damage and speed. The Barricade Turret fires a steady stream of traps in the direction of its target, blocking most bullets coming in that were shot to do ill. Nest Warden Render
Nest Guardian The Nest Guardian is the most offensive out of all of the Nesters. The Devastator bullets are a tad bit smaller than an Elite Destroyer's, but deal equally abominable damage and have equally insane health. The Swarmer auto turrets launch hives identical to Paladin's hives; big and one shot lethal. The Twister missiles create a large bullet storm, and also are one shot fatal. Summed up it is a one shot wonder in the most literal sense. Nest Guardian Render

Bob[]

Main arcticle:Bob

Bob is a Rare boss in Arras.io that can occasionally spawn in Siege. When it does spawn, it is the only Boss in it's wave, meaning that it can never appear with other bosses and can only spawn with eachother.

Bob vector

Bob is a fast boss and has a large amount of health, targeting the players rather than the sanctuaries. When it spawns, it is the only boss type to spawn in its wave, making them spawn exclusively in groups (just like Shiny Sentries). Groups of Bobs can be fairly dangerous, so you will have to be careful around them.

Celestial[]

Main article: Arras:Celestial

The Celestial is a Boss known for being much stronger than most other Bosses. Majority of them spawns mainly as being part of Siege, but also has an extremely rare chance to spawn on other game modes. Most of them consist of three layers (with the notable exception being Ragnarok), with the bottommost nonagon-shaped layer always consisting of Trapper auto turrets.

Final Bosses[]

These Bosses spawn exclusively in Siege as the final Boss of the game. These are randomly chosen between Ragnarok, Kronos, and Legionary Crasher. Realistically, these bosses require at least 10 tanks to defeat, and any less will result in certain game loss.

Ragnarok[]

Ragnarok-removebg-preview

Ragnarok is notable for its extremely large size, as well as its body consisting of four layers instead of the usual three of the Celestials. Its topmost pentagon layer consist of five Gunner Cruiser turrets, which have two cannons and two Cruiser spawners, while the second topmost heptagon layer has seven unique cannons that fire Auto-Smasher-shaped projectiles. Its second bottommost nonagon layer has nine Gem-shaped drone spawners, and the bottommost hendecagon layer has eleven Trapper auto turrets. It has extremely high health and resistance to damage.

Its second bottommost nonagon layer has nine Skimmer-like auto turrets, with the shorter, overlapping cannon having wider opening often known as ‘Alpha Skimmer Missiles’, and the bottommost hendecagon layer has eleven Trapper auto turrets. It has extremely high health and resistance to damage.

Legionary Crasher[]

LegionaryCrasherRender

The Legionary Crasher has 2 layers. The bottom layer has 3 sprayer turrets on the sides and 3 pillbox launchers. On the top layer, there are 3 Elite Gunner turrets on the corners and 6 spawners on the sides which do nothing. There are also spawners underneath the Sprayer turrets which spawn Elite Crashers. The Elite Crashers it spawns are larger than the usual elite crashers. The minions are referred to as Elite Legions in their kill notification (the only such notification that comes from a drone). Elite Legions are largely based on Elite Crashers. Other than by size, the Elite Legions also have some differences from regular Elite Crashers. The Machine legion is the counterpart to the old Elite Sprayer, with 3 machine (instead of sprayer) turrets. The Battleship variant has 2 turrets instead of 3, and the Gunner variant auto-spins like the older Elite Gunner.

Rouge Celestial[]

Rogue Celestials are generally weaker and smaller than regular Celestials. They are the rarest bosses to spawn. They cannot spawn in TDM, FFA, Maze, or Sandbox. They are colored the same as Rouge Palisades as well. They got removed on January 29, 2022. But after some months later they got re-added again.

Trivia[]

  • The Summoner is the only boss with a direct counterpart in Diep.io and Woomy Arras.io.
  • Before any of the non-Elite Crasher bosses spawn, a special notification will be sent.
    • When the strange bosses spawn, a notification “A strange trembling...” is shown .
    • The Celestials also have their own unique notification: “The world tremors as the celestials are reborn anew!”
    • The Rogue Celestials also have their own unique notification: “The darkness arrives and the realms are ripped apart!”
      • Each of the Final bosses in Siege are also shown to have their very own unique spawn messages as well.
      • Ragnarok’s spawn message: “Do you believe in Ragnarok?”.
      • Kronos’s spawn message: “The sky darkens as the ground slowly begins to crumble... The end is near.”.
      • The Legionary Crasher’s spawn message: "The Elite Crasher’s were all but disciples for what you have awoken... What have you done?"
  • The only Bosses to not use any types of Drones as of yet are the Elite Gunner, Elite Sprayer, and Elite Skimmer.
  • Bosses can earn XP when they kill tanks. This is easily noticeable in Siege, particularly with stronger Bosses like Ragnarok.
  • Bosses are on the same team with Polygons, and such, cannot be hurt by them, and vice versa.
    • Sentries and Arena Closers also cannot kill them, due to also being part of that team.
    • Because Polygons can reside in a player team’s Base unharmed (unless a Base Protector is present), bosses can attack players inside a base. Most cases happen in Assault, due to the lack of Base Protectors for the blue team, as well as Bosses mostly spawning fairly close to them.
      • Bosses, however, will not target players in bases, only their ammunition and turrets will.
  • Out of all the bosses in arras.io, the Elite Gunner is the only boss that doesn’t auto-spin as of an update.
    • Out of all the bosses in arras.io currently, the Legionary Crasher is shown to use lesser bosses (Elite Crashers) as minions.
      • The Elite Spawner Legion actually spawns very large Sentries.
        • Due to this, the Legionary Crasher is the only boss in Arras.io to have minions that spawn more minions.
  • The Elite Sprayer is the only boss to be fully reworked.
  • If you kill an unnamed boss (most notably in Siege), the message will say “You killed a visiting [type of boss].”
  • Ragnarok is formerly considered a Celestial variant, before becoming its own Boss type.
  • Kronos was previously known as Eternal, back when it was not officially added as a final Boss for Siege.
  • Alviss, Tyr, and Fiolnir, all called Rogue Celestials, are the rarest Bosses to spawn outside of Siege.
  • If an Elite Gunner spawns without a target, it will face right. This could apply for all bosses, however all other bosses have auto-spin enabled so it’s hard to tell.
  • There was once a bug that made every boss’s Auto Turrets grey, even if the base was colored. This was especially apparent with Celestials, however other bosses were effected as well.
  • Until a recent unmentioned update, the kill notification for the Celestials was "You killed a visting <celestial name>". Now, it’s "You killed <celestial name> the Celestial".
