Divine Metamagic is allowed in this game. I understand that many DMs think it is overpowered but it does cost at least 3 feats (Extend Spell, Persistent Spell and DMM), perhaps 4 or more if you count extra turning. So it's fairly pricey. Nevertheless I have added a couple of additional limitations in my game. If DMM is something you're considering I will post game information about the feat in the rules section.
