||Mana Sphere (x2)
The Wraith is a fiend that can be found in the later portion of Inside Sin, as well as in the Omega Ruins. Its elemental affinities change from battle to battle, so you never know what it will be weak or strong against until you try. Its first turn will be spent casting Doom on a single character, after which, it will cast Doom again, Death, or one of the tier 3 elemental spells. Despite the lack of physical damage, it is not actually armored, plus it is immune to Breaks. You can use attacks with delay attached to them to make battles easier.
