Magic Resistance. The mind flayer has advantage on saving throws against spells and other magical effects.
Innate Spellcasting (Psionics). The mind flayer’s innnate spellcasting ability is intelligence (spell save DC 15). ITT can innately cast the following spells, requiring no concentration: At will - deter thoughts, levitate. 1/day each: dominate monster, plane shift (self only) Tentacles. Melee Weapon Attack: +7 to hit, reach 5ft., one target. Hit 15 (2d10+4) psychic damage. If the target is medium or smaller, it is grappled (East ape DC 15) and must succeed on a DC 15 Intelligence saving throw or be stunned until this grapple ends. Extract Brain. Melee Weapon Attack: +7 to hit, reach 5 ft., one incapacitated humanoid grappled by the min flayer. Hit: 55 (10d10) piercing damage. If this damage reduces the target to 0 hit points, the mind flayer kills the target by extracting and devouring its brain. Mind Blast (Recharge 5-6). The mind flayer magically emits psychic energy in a 60-foot cone. Each creature in that area must succeed on a DC 15 Intelligence saving throw or take 22 (4d8+4) psychic damage add be stunned for one minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
If not, are there any non-quick and easy ways?
