Ambush (4e Feat Type)

Ambush Feats: Ambush feats are only available to characters with a class feature that increases the amount of damage you deal when you fulfil specific requirements, such as Rogue|sneak attack]] or ranger|hunter's quarry]] (these class features are refered to as "extra damage class features" in the feat descriptions). They allow you to apply extra effects to your attack when you use such a class feature, at the cost of one or more dice of extra damage. You must declare your intent to use any ambush feats before you roll your extra attack damage dice from your class feature. You cannot use an ambush feat if it would reduce the number of dice used for this class feature to 0. You can apply more than one ambush feat to any one attack, so long as you still deal at least one dice of extra damage from your class feature.
