Black Arrow Style

Prerequisite: Any martial class, trained in Stealth
Benefit: You gain a benefit with any of the following powers you possess.
Deft Strike (rogue): If you move into an obscured space or gain cover before making a ranged attack with this exploit, you can make a Stealth check against your target’s passive Perception as a free action to gain combat advantage against your target until the start of your next turn.
Twin Strike (ranger): While you are hidden, you can use this exploit to make a ranged attack, and if you miss with the first ranged attack, you can choose to cancel the second attack to remain hidden from your target. You can also remain hidden if you are hidden but miss with both ranged attacks this exploit allows.
