nrj +5 takes the place of the damage mod, if that sword is max dmg its worth a lot imo.
Free bump as i'm not experienced enough to give a price range and it is a really cool item.
I'd say at the moment 200k+... haven't seen too many +5 zodiacs yet.... and have seen a few askin for them... put it on high end startin at 100k and see where it goes
it is max...
