I honestly wouldn't have any issue with something like has been suggested a few times before, some manner of 'punching bag' to work out how hard you can hit using specific actions. But this will likely satisfy noone given people want these things to use in dungeons and I'd rather keep them as far from dungeons as possible so that DPS harassment won't be as big a problem as the vote systems have become. I mean, look at the threads that pop up every other day about vote abuse. Imagine how many will crop up about this if it ever became a thing.
