Fanatic

These monsters have a similar moveset to the Temple Masters, although they don't have access to the Blessing skills, and instead, they have access to a Lv. 2 Stored Attack called Soul Drain, which heals them by the amount of damage they caused with it. Due to this, make sure to protect your Reyvateil whenever she gets targeted, and dispatch them as quick as possible so they can't heal their allies.
