Nemesis staff deals smashing damage and has a hell of a knockback. Proposed "Lightwand" deals straight up energy damage on par with the Blackwand's negative damage. I offered the suggestion as a thematic alternative to darkness based attack. I'm certainly not against additional ideas, but I'm not sure what would be a good fit for a mutant based equipment power as the prestige powers are pretty much equipment based (magic axe, magic sand, magic wand, tech staff). In addition to trying to expand the options, I was also trying to maintain whatever balance exists with the original powers by expanding the choices without giving more power variation... as in, no healing or buff/debuff effects... just damage effects comparable to the existing choices.
