I actually want the RAW. Mark of Justice does not initially harm the creature affected, and under most situations, shouldn't do anything at all once the situation was explained. And even then, it doesn't do any actual damage: in this case it just makes the character sick. NOT sickened as in the mechanic, but sick. I don't see what the problem is here, or the conflict to begin with. If the monster is more or less friendly with me, so much that, as written, I'm considered its "trusted friend", why would it doubt me if I said " its not going to hurt in the slightest, and after 10 mins, it wouldn't be like anything has happened." The reason I asked this question, is cause, under the rules for Charm Person, if the creature is threatened by me or an ally, the spell breaks. That is why I want, specifically, some written rule that states casting a spell, regardless of WHAT spell, is considered a threatening action. From what I'm getting from Frankthedm, the creature must feel threatened, which goes back to perception, which we admitted is slanted due to being under the Charm. Unless the rogue spontaneously gained ranks of spellcraft, there shouldn't be any reason for it to resist, and therefore break, the charm. Correct me if I'm wrong.
