Spellcasting (Psionics). The githyanki casts one of the following spells, requiring no spell components and using Intelligence as the spellcasting ability (spell save DC 15):
At will: light, mage hand (the hand is invisible)
1/day each: contact other plane (as an action), plane shift, telekinesis
2/day each: detect magic, invisibility (self only), mage armor (self only), tongues
Multiattack. The githyanki makes three Astral Bolt attacks.
Astral Bolt. Melee or Ranged Spell Attack: +7 to hit, reach 5 ft. or range 60 ft., one target. Hit:20 (3d10 + 4) radiant damage.
Astral Step (Recharge 4–6). The githyanki teleports, along with any equipment it is wearing or carrying, up to 30 feet to an unoccupied space it can see.
Githyanki star seers believe that the stars are the eyes of the multiverse. They use their magic to contact ancient stellar entities such as Acamar, Caiphon, and Hadar, hoping to learn their secrets, then record these secrets in journals. They scour Wildspace in search of new entities as well, hoping to be the first to contact them.
