The Rockwell Arena is featured in the DLC: Aberration where survivors must defeat Rockwell.

The King Titan Arena, Desert Titan Arena, Ice Titan Arena, and Forest Titan Arena are featured in the DLC: Extinction as part of the map rather than a separate section. All of the bosses (Titan) summoned are within the map, rather than being found in their own Arenas.

The Moeder Arena is featured in DLC: Genesis: Part 1 where Moeder, Master of the Ocean resides during the mission.

The VR is featured in DLC: Genesis: Part 1 where Corrupted Master Controller resides. Survivors must have cleared enough mission to trigger the fight through HLN-A.

This is the last canon boss before ARK 2 takes place.

Harder difficulties in a particular boss will award the engrams from all previous difficulties.
²Ragnarok Arena contains Manticore and Dragon, which give their Tekgrams upon death. Defeating both unlocks the exclusive Tekgram listed.
³ This is the level required to enter the Easy Arena for Broodmother Lysrix, the lowest level arena.

Compatible Tamed Creatures[]

_{These restrictions do not apply to Extinction arena as the boss fight takes place inside the map rather than in a separate section of the map}

Entry Restriction:

A maximum of 10 survivors and 20 creatures are allowed to enter the arena. In the case of Tek Cave, a maximum of 10 survivors and 40 creatures are allowed, but only 20 creatures can be warped in at any point of time to the arena itself per warp.
Most Arenas restrict survivors to ground-only creature. There are a few exceptions:
- Scorched Earth - Flyers are permitted in this arena.
- Aberration - Climbers are permitted in this arena. This includes Enforcer, Megalania, Thylacoleo and Rock Drake
- Genesis - Sea Creatures are permitted in Moeder arena, and its drag weights are not considered when warping to the arena.
Exceptions for certain arenas are only valid for the listed arenas. E.g. Manticore Arena refers to the Manticore Arena in Scorched Earth but not Ragnarok Arena where you also have to fight against the Manticore.
A creature's "drag weight" must be less than 560. This is how much the creature itself weighs, not its carrying weight seen in its inventory.

To see this value in-game, place the creature on an

Elevator Platform with an empty inventory and no saddle.

Notes[]

Entering / Leaving the Arena[]

Others[]

Cryopod cannot be used in any parts of the boss arenas.

PC version

To be teleported into the arena AND out of the arena, you MUST be dismounted.

If you are mounted when you teleport into the arena, you teleport and dismount
If you are mounted when you teleport out of the arena, you teleport and dismount

Xbox version

If you are mounted when you teleport into the arena, you teleport and dismount.
If you are mounted when you teleport out of the arena, you don't die, but your dino gains a large amount of torpor.

Extinction and Genesis[]

Teleportation to the Titan summoned area or bosses in Genesis does not require you to dismount.

Equipment and Structure Restrictions[]

No structures may be placed in the arenas. So avoid forming plans that revolve on building. If you attempt to place anything, the message "No ground or snap point available" will be displayed.
- Grappling hooks may be taken into the arena, but once equipped in a crossbow they cannot be fired. (May be related to why Thylacoleo does not teleport into arena.)
- Quetzal, while itself can be warped into Manticore Arena, may not warp inside if it is wearing a Platform saddle with at least one structure.
All Tek gears and Tek saddles are banned from mainly the island Boss arena (Excluding Tek Cave/Overseer Arena) and Manticore Arena, and attempting to wear it inside when entering will either force unequip it, or drop at where the boss was summoned)

Item Losses[]

You will lose summon items and dinos only upon running out of time or dying within the arena. Similarly, if no survivor are inside the arena when the portal is pulling dinos in, all the dinosaurs will die immediately. This excludes the arena at Extinction and Genesis: Part 2.

Multiples changes[]

Due to the harsh consequences of a failed boss fight (see bullet point above), it is extremely advisable to prepare before attempting a boss fight. Watching online videos of other ARK players completing the Boss fight is a good way to elaborate your strategy in advance. However, there have been a lot of changes to the Boss Arenas during the development of the game, so ensure you are watching videos recorded after the last patch changing Boss Arenas. Also Singleplayer Bosses are weaker than Multiplayer Bosses, but never underestimate the Bosses.
