Bunch of summoners have been trying to farm Conversion Rolls in Ultimate Naverius after the update, given that Dia + Ares weapons are in.
Conversion Rolls seem to be forgotten in this. No one has found one, but they should be dropping here. As a matter of fact they should have been dropping for a while now. Even moreso, it'd be really nice if we could have the rolls in the Unique Weapon Badge shop since Nemesis and Raven are already there.
I'd use the item log to back my claim up but candy doesn't show up there anyways so.
I would also assume Substitution Roll is not dropping from Ultimate Lillipa. This roll is able to be gotten via title rewards, but is not possible outside of it right now.
