Mace Beam Volley or Power Boost?

My undead/pain MM finally hit lvl 44 yesterday. He has the Mace mastery. I'm thinking about the mace beam volley but power boost sounds like a good power because I think that it can help me with my heals. Which one should I get? Is Mace beam volley a good power? Please help. Thanks!

thermal heals, pain dom heals, dark -tohit, and FF bubbles are immensly good with power boost

i think the only secondarys that dont benefit much from power boost are traps and TA since they mostly use pseudo pets which arent affected by power boost

He mentioned that his secondary was Pain Domination.

I would go for Power boost with Pain Domination. As a Mastermind, most of your damage comes from your pets, and your Pain Domination powers like World of Pain, Anguishing Cry, and Painbringer would benefit greatly from Power Boost. I'm not saying MM's shouldn't take personal attacks, but when it's an extra attack versus Power boost, Power boost wins hands down.

Thanks guys. I'm going to choose power boost. Still not sure about Mace beam volley. Is it a decent power? How's the KB on that one? I might get it later on. Just wanna know if its worth getting. Thanks

Yeah, the mace powers are a bit stronger than your average blasts, but the redraw can be a pain. If you've got room in your build and want to add a bit more damage, then by all means take it.
