Reminder, we actually don't know if Inoda actually can do ANYTHING that causes damage with his abilities, so far the only trade-off of his nonsensical powers is that he's weak as all fuck and can't do absolutely any damage to anyone or anything else, so yeah, no, aside from being a NTR God and a Spymaster, his ability is actually quite useless for the main plots of SAO
(Also, they only exist in FOG's weird-ass unbalanced game-that-would-never-exist-in-the-actual-SAOverse system, they obviously wouldn't have existed in SAO, the god-like Cardinal system would have erased them from existence because of how unbalanced they were, or in any other VR world that made sense :3)
