Multiattack. The thri-kreen makes two Gythka or Chatkcha attacks.

Gythka. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) slashing damage.

Chatkcha. Ranged Weapon Attack: +5 to hit, range 30/120 ft., one target. Hit: 6 (1d6 + 3) slashing damage.

Chameleon Carapace. The thri-kreen changes the color of its carapace to match the color and texture of its surroundings, gaining advantage on Dexterity (Stealth) checks it makes to hide in those surroundings.

Leap. The thri-kreen leaps up to 20 feet in any direction, provided its speed isn't 0.

Parry. The thri-kreen adds 2 to its AC against one melee attack that would hit it. To do so, the thri-kreen must see the attacker and be wielding a melee weapon.
