Looks like there are lots of spoilers in here so I will ask my question. Sorry I don't know how to make a spoiler thingie.
In the sorcerers dungeon, if someone starts filling the plates but doesn't finish them, is there a way to reset ( IE empty the plates) so someone else can summon the master?? Or can a different person just finish filling the plates? It seemed like the empty plates became inaccessible when some plates were filled by another person (who left). Sorry if this doesn't make sense, my head is still spinning from that dungeon!!!
