Psionic Disintegrate, or also sometimes just written as Disintegrate, is a Psionic Ability reserved for the Githyanki race creatures, some of which the game bestows this ability to, mostly from the Baldur's Gate II: Enhanced Edition and Baldur's Gate II: Throne of Bhaal games.
Gameplay[]
The githyanki creature aims this spell at a detected enemy, and it is a ForceSpell cast.
The spell exposes the target to a Disintegrate effect that requires a Saving throw versus Death/poison to negate.
A failed save will kill the target creature, kick the sprite from the party, force all inventory to drop, and if "gore" is enabled, destroy items not flagged as "critical".
This so-called Psionic ability is basically a clone of the Wizard spell Disintegrate.
The spell effect can be blocked by Magic resistance, as well as Spell Protection defenses capable of deflecting/turning Power level 6 effects, such as Spell Deflection or Spell Turning.
Spell Immunity: Alteration can also stymie this spell, as well as the Cloak of Mirroring.
