11 extra damage

was looking at some more skills
if we each used barbs on enemy and had a winnowing and predatory season thats 20 extra damage for our attacks with 5 of that coming back as health
barrage also doesn +1 damage with no marksman skill so thats +21 so far, and a monk/necro with 12 blood using order of vamp would be 13 health steal for each hit so thats 34 extra damage from arrows and swords with no skill in them minimum. You will also be doing a little damage normally with your attacks. so lets say about 40+ damage per hit with each hit activating mark of pain for 42 damage.

Now lets do an example

1 N/R uses 100 blades skill with 6 W/R's and there pets around him, all the spirits are up 6 of those guys are mark of pained and barbed, order of vamp is up. All by him self he will do with my rough estimation 502 damage to each enemy around him if they all ganged up and sorrounded him, thats including all the health steals he's getting with order of vamp and that predatory season which is a steal of: 216 if he hits every W/R, if he hits all there pets too that is a steal of: 432 health. Now add a couple barrages from the N/R's and whats left of that very shocked group is dead.

edit: Btw with predatory season and order of vamp you wont need self healing lol. just use a barrage or 100 blades to get some health back
