LINK: Here is my gearset. It's pretty sub-par, but it's worked very well for me so far.
For Atmas, I used Lion, Beyond, and MM, but I recently got Blinding Horn, so I'll drop MM for it.

You should try setting Whirl of Rage. It's nice to open the fight with, and lets you use CA+Efflux on something. It usually does ~1.5-2k and stuns everything. After that I use Dream Flower, Ascetics Tonic (Which does NOT stack with Memento Mori), wait for Whirl cooldown then I BA+Charged Whisker and Whirl of Rage again.
I have Actinic, Yawn, and Thermal Pulse set for emergency use, but I haven't ever needed them yet.
