Question on spell DC bonuses

[Comett]

If you specialize in a specific field, i.e. Illusion. And you have Spell focus illusion trained, Greater spell focus illusion trained, and have an illusion modifier item (sceptor of illusion +1 say). Will all three of these stack? So now you would get +3 to the DC of an illusion spell?

Now do these bonuses also stack with those given by an item that gives spell penetration, so if I have a penetration item +2 for that appropriate spell level. Would I get +5 for that spell?

And my final question is how do I find this stuff out for myself?


thank you in advance.

I is my understanding that they will stack and it seems you have the formula correct.

the above link is a couple of posts down from yours as to how to find out for yourself. I dont know if you click it will work but I tried.

This is my greatest pet peeve... Spell Penetration (SP), despite its misleading name, has nothing to do with Spell DCs.

Spell Penetration is used to overcome a creature's Spell Resistance (SR). Only a handful of monsters have SR; Demons, Devils, Drow, Thaarak Hounds, Rakshasas and Vampires... off the top of my head.

The formula for SP is: Your caster level + SP Feats + SP Enhancements + Any SP item.
The formula for a Spell DC is: 10 + the level of the spell you're casting + Your casting stat modifier (Cha, Int or Wis).

And finally, to answer your question, yes SF: Illusion, GSF: Illusion and an Illusion Focus will all stack to grant a total of +3 to your spell DC.

Well I stand corrected and thank you for the excellent explanation. I know those pesky flesh golems in the orchard have insane SR that I feel is more likely spell immunity.

Well, Golems in pen and paper are generally immune to magic(except some conjurations). So the insane SR of DDO golems is an attempt to mimic that.

Which is fine if that is how it is meant to be then so be it, I was just throwing them in there as a monster that no matter what you equip forget about damaging them with spells.

feats and items stack.

You can get up to +4.

+2 from feats and +2 focus item

By the way OP, +2 school focus items are not common or available in all schools. They only come on the items Staff of the Petitioner (gtr necro, gtr ench) from abbot raid and Black Dragon Scale Robe (gtr evo) from gianthold scale turn-ins.

And the Dreamspitter from the Reaver (greater enchantment).
