The last party member to be introduced to Etrian Odyssey 2 Untold is Chloe the War Magus.
War Magus possesses some of the most devastating debuffs in the game. Central to a War Magus’ strengths are the War Edge skills.
When equipped with a sword, War Magi can apply a seven-turn debuff that reduces an enemy’s Attack or Defense, as long as the enemy currently has an ailment. Devastating for boss fights, especially when followed up by the Sovereign’s Ad Nihilo skill to convert the debuffs (on their last turn, naturally) into Almighty damage.
Check out the War Magus’s strength in the trailer below.
