This skill may see more use now with the DK cost reduction, but it needs some improvement. It's damage is low because it has a strong synergy, but that synergy is almost unuseable. There's two ways the skill could be improved so that it sees use:
1. Open up the synergy to everyone (currently it's ranged only). Since this is a stamina skill it makes sense that at least other melee fighters can use it
2. Increase the damage, area of effect, or make it a dot.
In keeping with the undaunted theme, really the synergy should be made useable to everyone in the group.
