meh, I have to disagree. Its nice to have some energy back. But thats only 3 netto at 16 scythe. And activating it costs 10 e. So in this build its impossible to use propperly. A zealous scythe with 5e scythe skills works much better. That way you can spam your attack more often.
And I'm not a big fan of avatars (accept for AB). When activating there good. But they have a 2 minute downtime. In which there useless. Avatar of balthazar is IMO the best skill for running purposses. Not for normal PvE. Hmz, maybe against summoned creatures because of balthy's holy damage.
You can better take an attack skill which doesnt have a huge down time. Like my Elite : [skill]Reaper's Sweep[/skill] , +42 damage with 16 scythe. and Deep wound under 50 % health.
Offcourse this is my oppinion. If you feel balth. suits you. I'm not going to stop you =P. Just told you an alternative.
