around 34 minutes ago i told you the spirit behind Nero was Akkiude. so he wouldn't have a different DT for each weapon. and because it is a form of devil trigger it would be treated the same as any other(at least in my game idea).
my idea involves akkiude slowly gaining more influence over Nero. (Devil Bringer spreading,more powers, personality changes, Akkiude becoming more solid etc.) that is somewhat slimier to your idea but it=n my idea it is a slow process as part of the story.
your idea is good but it won't work in my version of dmc5.
(that and i don't think Kyrie would like it very much if Nero looked like phantom
. Ziz would love it though:lol:.)
