Clustered Shots for Energy Resistance

[Dark Sorcerer]

Is there an equivalent to Clustered Shots for Energy Resistance?

I want to total the damage from Flaming on arrows before applying the demon's fire resistance. Is there a feat for this?

Not that I am aware of.

No game feat, but certainly a feat that you could request to play in a home game. It would be just as balanced as clustered shots. Give it all the same prerequisites a clustered shots.

Many people forget that one of the rules in Pathfinder is that GMs can make feats, classes, etc... Unless you are talking PFS, I think that is the way to go.

This is actually sort of how it worked in 3.5; Energy Resistance was per round. So if you blasted a monster multiple times (or you and another mage teamed up to do it) before his turn came around again, he would ignore the first 10/20/30 and eat the rest. PF changed it to per attack.

I don't mind the change personally, but since it worked the other way in 3.5, that may help you convince your DM to change it back if you feel strongly about it.
