Sneak Attack

[Saliarie]

If Im a fighter in sneak mode and swing a sword that says "Sneak attack" in the suffix will it do sneak attack damage?

What about when I use my cleave option?

[Partisus]

Sneak attack bonuses, whether from class granted abilities or from weapon properties, apply to any attack on an enemy that is not targetting you. Fortification/crit immunity will stop sneak attack damage, as it is crit based.

Sneak attack works with cleave too, so you can do a sneak attack on multiple mobs with once cleave. The animation is pretty slow when using a 2 hander or two weapons but is more effective with sword and board as its much faster.
