Illithid’s Kiss

5-level Transmutation

You grow four tentacles from your face, similar to those of a mind flayer. For the duration, you gain the following attack, with which you are proficient: Make a melee spell attack against one creature. On a hit, you deal 2d10 psychic damage plus your spellcasting ability modifier. If the target is Medium or smaller, it is grappled (escape DC 15) and must succeed on an Intelligence saving throw or be stunned until this grapple ends. If you begin your next turn grappling the stunned creature, make another melee spell attack against that creature. On a hit, you deal 10d10 piercing damage. If this damage reduces the target to 0 hit points, you kill the target by extracting and devouring its brain.
