I'm trying to figure out how to straighten out my Arcane Circle, since the base is kind of warped. I'm aware of the method of hot/cold water with small minis (to straighten out sword tips), but I'm not sure how to apply it to this big boy. Any confirmed methods to flatten the base? (I'm reluctant to glue it to another flat surface.) I tried to look through the forums and couldn't find anything explicit. Thanks!
