Duly noted. Though, does that mean, with your correction, that extinguishing Formulae fire is DC 15, and extinguishing mundane fire is DC 20 ?
I think that the only formula that actually functions as normal fire is the 1st-level Ignite formula. Everything else is defined within the formula, and therefore has the standard DC of 10 + formula level + ability modifier. I
think. After writing three hundred formulae, it's hard to keep track of them all.
Devoted Pyromancer's DC boost is really to ensure that your burn ability remains relevant, as well as rewarding you for playing with fire from other sources.
(I'm going to stop invading the thread, I swear.)
