If it is the last enemy standing, it will use Thrust Kick (that can also be learned by Kimahri), which ejects one character out of the battle, preventing them from gaining any AP and leaving only two party members left. So players should destroy this enemy first before attacking the other enemies. They will often appear with two Fallen Monks (flamethrowers), or with YAT-97.
The YKT-11 will drop armor with any combination of up to three elemental ward abilities and weapons with Strength or Magic 5% bonuses. These drops are identical to the drops of the other machina in the Zanarkand Dome, YAT-97.
