We're just a few days away from the release of Etrian Odyssey IV now, but there's a few classes left to cover. The Arcanist is weak against enemies as far as dealing direct damage goes but specialize in crippling enemy parties with their diverse range of attacks, including a Releasal spell that hits them again and again.
Unlike other classes, the Bushi is a beast-like character whose specialization is in hitting the enemy hard. Their Blood Surge skill sacrifices HP and TP every turn in order to increase their offense, and they also receive further bonuses for having low HP.
Etrian Odyssey IV: Legends of the Titan releases next Tuesday (February 26) on the 3DS eShop and in retail.
