Question about Barrage.

When weilding a vampiric bow and using the barrage skill, do you gain life for each target that you hit or just for one shot?

What I mean is say that if the bow has a 5/-1 vampiric string. If I use barrage and all the arrows hit, do I gain 25 health or just 5 health?

Yes, every arrow that hits you get bamsmack +5, counter that with a dual shot next? can you say usless monks?
