Multiattack. The thri-kreen makes two Gythka attacks and one Chatkcha attack.
Gythka. Melee Weapon Attack: +7 to hit (with advantage if the thri-kreen is missing any hit points), reach 5 ft., one target. Hit:13 (2d8 + 4) slashing damage.
Chatkcha. Ranged Weapon Attack: +7 to hit (with advantage if the thri-kreen is missing any hit points), range 30/120 ft., one target. Hit:7 (1d6 + 4) slashing damage.
Leap. The thri-kreen leaps up to 20 feet in any direction, provided its speed isn't 0.
Parry. The thri-kreen adds 3 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.
Thri-kreen gladiators relish opportunities to test their mettle in combat and often paint their carapaces with the blood of their enemies.
