Since Improved Precise Shot allows your ranged attacks to ignore any concealment less than total concealment, does a creature with Sneak Attack and Improved Precise Shot have any need for the Sniper's Eye rogue talent in order to inflict Sneak Attack on an opponent with partial concealment? Is there any benefit to having both Sniper's Eye and Improved Precise Shot?
Your ranged attacks ignore anything but total concealment and cover.
Prerequisites: Dex 19, Point-Blank Shot, Precise Shot, base attack bonus +11.
Benefit: Your ranged attacks ignore the AC bonus granted to targets by anything less than total cover, and the miss chance granted to targets by anything less than total concealment. Total cover and total concealment provide their normal benefits against your ranged attacks.
Normal: See the normal rules on the effects of cover and concealment in Combat.
Benefit: A rogue with this talent can apply her sneak attack damage on ranged attacks targeting foes within 30 feet that benefit from concealment. Foes with total concealment are still immune.
The rogue must be able to see the target well enough to pick out a vital spot and must be able to reach such a spot. A rogue cannot sneak attack while striking a creature with concealment.
