Combat
Mind flayers like to fight from a distance, using their psionic abilities, particularly their mind blast. If pressed into melee combat, a mind flayer lashes its enemies with the tentacles ringing its mouth.

Mind Blast: This attack is a standard conal AOE. Anyone caught in this cone must succeed at a Will save (DC 17 and higher) or be stunned for 6-30 seconds. Mind flayers often hunt using this power and then drag off one or two of their stunned victims to feed upon. This stun can be removed with the Heal spell.

Extract Brain(Ex): A mind flayer that begins its turn with all four tentacles attached and successfully maintains its hold automatically extracts the opponent’s brain, instantly killing that creature (Ignores Death immunity). Since this ability takes some time to perform, they will only attempt to use it on creatures they have successfully mind blasted. It is possible to survive this attack by quickly moving out of melee range before they can complete their animation.

Spellcasting: At will: Hold Monster, Dominate Monster, Lightning Bolt (Save DC 13 + spell level + mind flayers charisma bonus).

Telepathy (Su): Mind flayers can communicate telepathically with any creature that has a language, within a great distance. (Mostly a flavour thing, but this explains why Yaulthoon and some other mind flayers are able to speak to you through your mind at a great distance.)
