| Overview | Combat |
This page focuses on The Netherbrain's behavior during turn-based combat gameplay.
Spells and abilities
Range: 30 m / 90 ft 
Honour Mode
Recharge: Per turn
Conditions
- - After using Karsus' Compulsion on the Netherbrain
- - If a natural 20 was rolled on the final check to dominate the Netherbrain at the Morphic Pool it will have this condition, which will greatly reduce its HP.
Enemy allies
- Dominated Red Dragon
- Illithid Arcanist x4
- Tentacle x16 (hidden under the brain's surface until approached)
- Nautiloid (Creature) (appears after a 4 turn countdown and begins summoning Mind Flayers and Intellect Devourers)
Conditional enemy allies
- The Emperor (if the player chose to free Orpheus)
- Dream Guardian x4 (if the player chose to free Orpheus)
- Countermeasure x4 (if the player chose to trust the Emperor)
Encounter
Atop the brain
- Dimension Door, Arcane Gate and Misty Step are all useful spells to have assigned or distributed as scrolls for moving from the entrance Atop the Netherbrain to the Crown of Karsus.
- Stepping directly on the brain's surface will summon hidden tentacles, so it may be easier to approach from the two platforms on either side. Otherwise, if intending to sprint across, it is helpful to use a character who can avoid Opportunity Attacks, such as one with the Mobile feat.
- Globe of Invulnerability is also useful for protecting the caster of Karsus' Compulsion. However, the nearby Mind Flayers will still be able to
creatures inside the globe, which ends the spell prematurely.
- Tossing Mind Flayers over the edge with moves like Telekinesis will not kill them, as they will just reappear atop the Netherbrain.
- Only party members and Orpheus or the Emperor can enter the Netherbrain's psyche (or The Unbreakable Will of the Netherbrain), so once the portal is open it is no longer necessary to continue fighting other enemies.
Inside the crown
- On Tactician, the Netherbrain will have 450 hit points.
- The Netherbrain's hit point total can be reduced by 20% for the final fight via if the player rolled a natural 20 for the final skill check to dominate the Netherbrain in the Morphic Pool.
- The first attack each round against the Brain will cause it to use Retributive Brainquake, which will damage and potentially
everything in range. - The Brain will use Orb of Negation to summon several orbs which cause damage at the end of the next round. These orbs will destroy the platforms beneath them, so it is important to move characters off of any marked platforms. Further, the brain should be quickly killed since every platform will be destroyed in only a couple of turns.
- It is strongly recommended to have one's entire party near the portal before casting Karsus' Compulsion. Once the final fight against the Netherbain begins, it is possible for the Netherbrain to negate all platforms near the portal, preventing party members caught outside from entering.
