Your Subterfuge Skills create an attackable Shade Totem for [6.0 - 8.0] seconds. Any damage it takes is replicated onto surrounding enemies at 50% effectiveness. This effect is treated as a Trap Skill. You may only have 1 Shade Totem active at a time.

One of a pair of twin daggers, forbidden from ever meeting. Bitter voices whisper from the blade.
