You must have forgotten that CR, the issue at hand here, is only pertinent to combat itself to begin with!
If it's an RP modifier, it doesn't belong on the CHALLENGE Rating.
Bluff, Sense Motive (Feint)
Tumble
Hide, Move Silently (surprising opponent flat-footed)
Listen, Spot (Avoiding getting surprised)
Perform (Bardic music abilities)
Ride (AC for mount)
Concentration (casting on the defensive, avoiding losing a spell)
Spellcraft (Identifying a spell for purpose of counterspelling)
Knowledge Arcana, Nature or Religion: Number of Epic Spell Slot
There are plenty skills useful in combat, even from a strict fighting challenge approach. Granted, Knowledge: Hyperstring Theory or Craft: Pottery will not affect combat, but that don't mean none of them has influence on the fray.
And then again, the
Agressive Pseudodimensional Translation spell may require a K. Hyperstring Theory check in order to successfully phase out of the universe a target; while building clay golems is cheaper if you don't have to hire a potter.
Speaking about CR, Craig (hello!), could you send me that document ? It may helps me finding a correct CR for a certain creature I'm working on...
