How does the Burning Spell metamagic interact with spells that have additional effects triggered "when the target takes damage"? For instance, would a Burning Sirroco exhaust someone even if they left the area agter taking damage the first time?
If you are a multiclassed spellcaster and a feat has a caster level as a prerequisite, is the caster level the combined lever of all your spellcasting classes? Or just one?
