The Tavern

You can use it evoke rage while silenced, but otherwise it seems like Trog's rage is as good or better.

I know amulets of clarity are grayed out for Ashenzari worshipers. I'm trying to understand why it isn't the same for amulets of rage and berserkers. Is there more to it, or is this simply an oversight?

Unlike Trog berserk it doesn't have any hunger cost on use, only the regular hungering effect when berserk ends, which is a highly important consideration. (Edit: just to clarify because I'm sort of worried, this isn't serious and the hunger isn't important at all).

(Also like you even said, you can use it while silenced, so it's obviously not actually useless).

OK, that makes sense. Thanks!

or if you're under penance assuming you can actually make trog mad at you.
