Luther's BB is a single target that can cause paralysis. but it does take 15 BC to fill up. Instead of using Luther for arena, it would be better suited for Deemo as she can generate 34 BC with just normal attacks.

Luther can serve better in Frontier Hunter considering that he has the same buff on his SBB as Douglas with the spark DMG increase. He can generate 28 BC with his SBB, which is lower than Douglas, but he doesn't have the penalty of reduced BC generation.
