Innate Spellcasting (Psionics). The githyanki's innate spellcasting ability is Intelligence. It can innately cast the following spells, requiring no components:
At will: mage hand (the hand is invisible)
3/day each: jump, misty step, nondetection (self only)
Multiattack. The githyanki makes two greatsword attacks.
Greatsword. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit:9 (2d6 + 2) slashing damage plus 7 (2d6) psychic damage.
The warlike githyanki and the contemplative githzerai are a sundered people-two cultures that utterly despise one another. Before there were githyanki or githzerai, these creatures were a single race enslaved by the mind flayers. Although they attempted to overthrow their masters many times, their rebellions were repeatedly crushed until a great leader named Gith arose.
