Though the road may be harder, you have tempered your might with mercy.
Prerequisites
Ability to weave one or more veils.
Benefit
When you weave your veils for the day, you may select one or more of your veils that deal damage. Any damage dealt by the selected veils becomes nonlethal. This does not change the type of damage inflicted, a veil that inflicts fire damage inflicts nonlethal fire damage instead.
The benefits of this feat are not shared by attacks and abilities used by creatures created by a veil.
