How to play:
This build require to calm down before taking any action. Blood is a Power takes 33% of your life when casted and with 0 recharge time you can kill yourself immediately. Try to not use this skill more then two times at once or...you will die. :)
Every skill in this build, except Blood is a Power, is to heal you after using BiP. Use those skills as often as you can to keep your health at max level.
Try to avoid any direct contact with opponents (I mean - run ;)). On warriors use Enfeeble.
Stay behind your team and cast BiP on casters from time to time. Especially on Monks.
