Seismic Slam
Decent weapon dmg, but that is not the best thing about it. Knockback, insanely good AoE knockback. It will help you survive A LOT. If it were not for seismic slam, I would still be struggling with Belial on inferno. Once I picked Shattered Ground rune, it became piss easy fight and problem of adds on phase 1&2 was solved. Cracking rift rune is also decent, if you want some more weapon dmg at the cost of smaller aoe and worse knockback.
