It has a 33% chance of countering any attack by using Wrench on itself. When killed, it will use Wrench on a random party member, dealing moderate damage. For this reason, it is suggested that Terra uses Magitek to defeat it, as this stops it from using its final attack. By the time the player must face them without the Magitek Armor, Terra should be at a high-enough level to survive Wrench without taking too much damage.
