really... it isn't about the physical damage, the barb is going to take poison damage per second and the barb hasn't got enough psn resistance to counter it per second.

Go back to 1.09 builds to figure your shit out.

if ama uses 37 x 451psn over 12 seconds:
- Ama will have so low life u can finnish here before u ever die from this damage.
- 451 x 37 = 16687 damage.

If u have -100plr and 75pr in hell:
Damage over the total duration which is now 24 seconds: 16687 * (1-(-100/100)) * (1-(75/100)) * 0,17 = 1418 damage over 24 seconds. Barb has like 7,2k life if BVA. 7400/1418 = 5,217164 * 24 = 125 seconds for psn damage to kill you...
DPS: 16687 * (1-(-100/100)) / 12 * (1-(75/100)) * 0,17 = 59 life per second.

So will you take the 59 DPS from psn scs over the the DPS increase forexample 37 x 3max/ar/life scs would give u??? Go back to 1.09 urself, psn scs don't work well anymore.

The wisp is to misslead GA's and to abs a little vs that bolt dmg.
