In Itachi Edo's chase, which has the name Amaterasu, add the Amaterazu debuff. It doesn't make sense for the ninja to have a skill with the name Amaterazu and not cause this debuff. And of course it's Itachi, he uses Amaterasu, so it's only fair to implement this. I also think it's feasible to do this with Sasuke Rinne since it's the same situation.
