I couldn't finish 'em. Looks like this's gonna get complicated.
The Elder Treant is an enemy in Final Fantasy IV: The After Years. Elder Treants are powerful foes, as they have high physical power and can further it by casting Berserk on themselves. Berserk is sometimes cast as a counter to magic, so if one uses magic, they should make sure it deals enough damage for the rest of the party to finish off the foe.
Treants are creatures found in the Dungeons & Dragons roleplaying game.
