Need a good AOE

Im currently using a dual wield mace build, but I cant seem to find a good AOE. I've tried Infernal Blow, but I haven't taken much of a liking to it since its only an AOE when you kill the opposing enemy. I cant use cleave since I need a sword or axe. Is Lightning Strike any good?

I think ground slam should work fine with dual wielding maces. Haven't tried out lightning strike yet so don't really know about that one.

I thought ground slam was only 2 handed maces?

Edit: And staves?

Well you can use Leap Slam, but it only uses the main hand weapon. Ground Slam will work the same way, only your main hand weapon will be used, and it must be a Mace (or 2 handed mace, staff). Another choice is Lightning Strike, LS would alternate weapons used while dual wielding, so it might open up some interesting, clever uses of different weapons used.
