The rune for Spirit Barrage, Phantasm, deals damage over time in a small area of effect. If I overlap them and an enemy is standing on 2 or more at once, does it take double, triple, etc. damage? Or can an enemy only be affected by a single Phantasm at a time?
I've tried this pre-1.0.4 (since my main was a WD), and it stacks, adding another Phantasm on the area. Most likely it still works.
