With an affinity for Lightning, Wisp Projector is evocative of the Willowisp enemy, and fittingly its Lightning Absorb is effective defense against them. The Wisps it supposedly projects most likely refer to the Spirits it can summon; although not particularly high level, Heart of Wolverine can give a small help to physical fighters, and Oak Sage can give a nice boost to life.
