If a spellword uses words of two different schools (conjuration & evocation for example), does a character that has both relevant Spell Focus feats increase the DC by one or two?
Likewise, does Elemental Focus stack with Spell Focus?
You can gain this feat multiple times. Its effects do not stack.
They're untyped bonuses though, so Spell Focus and Elemental Focus should stack with each other.
"Wordspell Schools: If a wordspell has more than one effect word, it can belong to more than one school, although it never benefits from effects based on school (such as Spell Focus) more than once. It can take penalties based on school more than once; for example, if a target has a bonus on saving throws against necromancy and illusion spells, that character would add both bonuses on the saving throw if the wordspell is of both schools."
Thanks Aurete; I find the Words of Power interesting, but something about the way it's layed out seems to make it hard to find the relevant rules bits.
VRMH, that's good to know; I'll get rid of my Evocation Focus but keep my Fire Focus feat.
