Your critical hits are more effective while you attack from the shadows.

Prerequisite(s): Dex 15, 5th-level shadowdancer

Benefit: Whenever you score a critical hit while both you and your target are within a dimly lit (or darker) area, you gain a +2 bonus to your attack roll to confirm the critical hit and the damage multiplier increases by 1 (for example, from x2 to x3).
