This question has the tag mastersummoner, which should be master-summoner per the guidelines that spaces should appears as dashes in tag names.
Seems stupid to ask a mod for something so simple, but the site won't let me fix this tag:
You are attempting to create the tag [master-summoner]; however the tag [mastersummoner] already exists! If you think this new tag should be allowed, raise it on meta
(This is assuming that we need the tag at all, which I'm unsure of but was going to leave for someone who's more Pathfinder-y to worry about.)
