Eh, when it comes to puddles, I am quite sure there are already mods to remove those from certain spells. I don't like how puddles are implemented - they adhere to D:OS2 ruleset, not D&D ruleset, feel out of place and don't play nice with other mechanics, like concentration.
They also really mess with evokers. Even though an evoker is supposed to be able to shape their invocation spells to avoid damaging allies, the giant burning puddle on the floor says otherwise.
