Spell Resistance???

[Ogrork the Mighty]

How come I can't find the rules for how to calculate Spell Resistance for a monster?

I've checked the Monster Manual, the Rules Compendium, the DMG, Savage Species, and can't find zip.

Can someone point me to a rules reference?

SR isn't capped by level, CR, ECL, or any other quantifier. If you're creating a new monster, go with a number that makes sense and tweak with it in play until you get it perfect.

It's not a formula for some monsters, just assigned.

It's often around CR+10.
