Spell resistance

[Xandor Loriland]

Does anyone know the actual formula used to determine if a caster can penetrate spell resistance.  I am interested in knowing the factors that go into it to figure out how best to train a character to be good at penetrating spell resistance.  Thanks.

1d20 + caster level + any feats

[LoganGrimnar]

d20 + caster lvl

[LoganGrimnar]

*grins* beat me by a second

[Xandor Loriland]

Ok so level and feats are all you can do then.  Thanks for the quick answer.

[LoganGrimnar]

there are also a number of spells that lower SR if you cant beat it, such as Spell Breach and MD, hit something with one of thouse then your chances are alot better.

[Xandor Loriland]

Thanks again.  Good info to know.

Clerics can't cast Mordekainen's Disjunction, though.

[LoganGrimnar]

good point, well they can still cast greater dispelling, so if the SR is a spell, you can dispell it. im pritty sure disspells pass trhough SR. But clerics can also just run up and hit things if they cant get past the SR.

I thought also the level of the spell you cast, adds up.

[FlameStrike]

Yep, Spell Breaches and Dispels pass through SR and even Spell Mantles last time i saw. And yeah the penalties to SR stack if you cast multiple Breaches or Mordekainen's .

[LoganGrimnar]

i dont think so, but feel free to test it and let us know

[Filatus]

Hmm yeah, spell level is only used for the DC, I looked it up.

I also read somewhere that you can't lower a monk's spell resistance.

[FlameStrike]

Could be because a Drow's SR is granted by a subrace skin, but when Spell Breached, or Disjunctioned, Syn's SR was lowered more than once.

 I don't know about Monks, but it doesn't make much sense if their SR can't be lowered, though if that's indeed the case, more power to them.
