question about VSF

why the necro need 1 hp?
what its giving to him if he will die wan he using BiP

Having 1 health and using a skill that sacrifices 33% of your health means you won't sacrifice ANY health. It won't kill you, so you can spam BiP on as many people as you want as often as you want and not worry about getting healed. Only problem with having only 1 health is that any damage you take will kill you instantly. So to run it, you need to know how to manage aggro and stay out of combat.

last time i did VSF, bips are needed to complete VSF in a decent time, but spirits rape the 1hp bip. so the FS ranger needs to take care of it with consume soul. which most of they fail. and so he kills frozen soil. waits mobs get ressed and u can start all over again. which is the main reason i dont do VSF
