FEATS

Sneak Attack (Expert)

When you make a surprise attack (see Surprise Attack), you do +2 damage. You cannot surprise attack an opponent you cannot perceive (due to concealment or some other effect), and opponents immune to critical hits suffer no additional damage. Opponents who cannot be surprise attacked are also immune. You can take this feat multiple times, increasing your damage bonus by +1 each time, to a maximum of +5.
