Very similar to Ran and Latio, Wiz's Skill is a 3x Strong Elemental attack that hits the enemy's Elemental weakness. This makes her quite effective as a universal attacker, though obviously she falls a little short compared to some other Elemental attackers with the trade-off being that she can hit anyone equally. That said, she's quite potent when it comes to dealing with multiple enemies with varying elemental weaknesses.
Taking cues from Rouge , Wiz can Lifesteal the damage she inflicts and Heal the Party accordingly. Given that Wiz can hit the enemy's Elemental weakness, she can Heal quite a bit of HP (especially if used with Enhance Cards)!
Unsurprisingly, she gets hit with the nerf bat for Colosseum and Duel Match, making her Skill quite weaker. So it's probably not entirely best to use her there. Aside from that though, she's a great card to have, especially since the Green versions of Ran and the like are pretty rare. Also notable is that Wiz does have a bit higher Attack than similar Cards, making her great for putting out damage.
A fantastic Sub, Wiz grants an Unconditional 30% Skill Boost to ANY card! And if that wasn't enough, if you target a single foe, you can further increase it to 35%, though this comes at the cost of 5% HP Recoil damage. (Fairly similar to Reika in some regards.)
Needless to say, Wiz is an amazingly powerful Sub to utilize for almost any Card in your deck!
Wiz is a powerful lich wizard and formerly one of the Devil King's generals. She was tasked with maintaining the barrier surrounding the King's castle, though she eventually leaves her position under a neutrality agreement which prohibits her from interfering with the King's army as long as non-combatants are not targeted by his forces. She is a timid and kind woman who uses her powers to assist civilians and lead lost spirits to the afterlife. She runs an unsuccessful magic shop in Axel which is later managed by Vanir, in which she is treated like a slave worker.
