What atmas you using?

I find Griffin Claw + VV + Apoc on /SAM really good and u should get 3-4k when u proc a triple attack.

I had a few 3k with just VV RR and Griffion last night without SA (wasn't at 100% tp tho)

As for Gear i agree on the capping attack with gear then using atmas to boost the base DMG (Griffin/Mounted champ/Smiting blow)
