I like shields take damage and can prevent damage. Let’s play more with that!
Feat 6Fighter Stance
Prerequisites Everstand Stance
You’ve practiced with the shield to the point even splinters will save you in a fight.

How about this for a feat to deal with some splash damage?
General
You get used to dodging the collateral damage of most things. When you are subject to splash damage, you may make a Reflex saving throw to negate the damage. The DC is equal to the original effect or if no save is available, it is equal to the class saving throw of the person causing the effect or 10 + the CR of the creature or item level.
