When an area attack detonates around you, you use the chaos and flash of energy to duck out of sight.
Prerequisite: Hide 9 ranks, evasion.
Benefit: If you are caught within an area attack whose damage you avoid completely due to your evasion or improved evasion ability, you can make a combined Hide check and a 5-foot step as an immediate action. You can attempt this check only if there is cover suitable for a Hide check, and you can take your 5-foot step into cover before making your Hide attempt.
Special: If you have the hide in plain sight class feature, you do not need cover near you to attempt the Hide check allowed by this feat.
