Do Soul Drain and Vortex Stack?

[PsiSoldier]

Yeah they are the same effect. They both suck life and fatigue out of the enemy (or anyone else for that matter) and give it to the caster. Its just that Soul Drain does it on a much larger scale where Soul Vortex is only the area around the caster.

There is the possibility that at the point where the caster is healed and reinvigorated that the Health and fatigue gained from the Soul Drain would override any gained from the Soul Vortex rendering the Vortex pointless. But if each affect was applied separately then it should work for sure.
