Only just saw the entry on how to report for bugs, though, I'm not sure this is one as it may be intended to work like this (read above posts)
Name: Cyrus Mehdad
Where: Anywhere.
When: Any time
What: Combat feat: Combat Absorption
Recreate: Read above, but also, What's the point of having energy resist and Combat absorption if the Energy resist is considered the only feat and absorption treated as an item?
Ideas: One of two options: That both feats should stack, since I've chosen Resist Acid (+5) and combat absorption (which is +8 atm, will max at +10), they should give +13 (+15 eventually) for Acid as a base. This makes sense to me, while other combat absorptions should be +8 [+10 eventually] (also, this is only while the Combat Focus is active, so it makes sense that it should be additive).
Second option: That the combat feat could override the resist feat, and thus give that as a base, but would obviously make the resist feat pointless for that given element.
