I've been thinking about working on the Periodic Table elementals (titanium? chlorine?)
However, I just wanted a suggestion for one of the powers that a Large carbon elemental could use. Maybe it could somehow gain a bonus to attack or damage (or both) rolls if it were on fire (coal?) We're going to meet it in an abandoned mine.
My party is a stereotypical group of 4 with a ranger, wizard, fighter, cleric arrangement, if that helps.
Any difficulty level welcome.
