The Giga Ant is a common enemy, it is weak and has neither an element nor special attack, though it has a slight immunity to the death affliction. It looks like the other ants of the game, except it's black-grey.
Upon defeating a giga ant, you will recieve approximately 17 experience and 4 dagols. You also have a 3% chance of recieving an Herb Extract. (Please note, this may change depending on your party's luck scores and any items you're wearing.)
