How does the game determine Spell DC for monster spells?

HousePet

Got nothing to do with EE sorry, but I can't find an answer anywhere.
Say for example I have a creature with only levels in the Undead class and I give it a spell (such as Negative Energy Ray) using the Special Abilities tab.
What stat does the game use for determining the modifier to spell DC?

DerpCity

IIRC, it calculates it like its a normal spell, but instead of calculating the Caster Level from the Monster's level it calculates it from the indicated Caster Level and uses the Charisma Modifier as its primary spellcasting attribute. Kind of wish you could set the caster level higher than 15, personally.

Balkoth

10 + Spell Level + Charisma Modifier, IIRC.

Gets different for stuff like dragon breathes as those use HD.

Awesome thanks.
I presume that is Charisma for all races, not just Undead?
I've already got a wrapper function around GetCasterLevel() which now has the ability to be overridden by a local variable on the creature.
Was pondering doing the same for SpellDC.

Its such a hassle making sure the monsters obliterate the players when the spell abilities work in odd ways...
