Tunnel Armor

Tunnel Armor,  It is encountered by Locke and Celes on their way through the South Figaro Cave. It can be heard drilling through the dungeon on the second visit. As the Tunnel Armor emerges from the rear part of the cave, where in the World of Ruin a passage leads to the submerged Figaro Castle, the Gestahlian Empire was likely using the machine to try and dig to the castle before it was ordered to prevent You, Locke and Celes from escaping. The Tunnel Armor attacks using almost entirely magical attacks, casting Thunder, Fire, and occasionally Poison and Magitek Laser. Its only non-magic attack, besides its normal attack, is its special attack, Drill, which does high physical damage to a single target. When the fight begins, Celes warns Locke the Tunnel Armor uses a lot of magic, and says she can absorb its spells with Runic.
