Also Dec, mind posting your Psy build?
This is theoretically her max damage build if you're building her as a hybrid, which is her current top damage spec.
(not my screen cap but stolen from the forums...my ultimate is only rank 7)
All her own uniques are the best choices, though you could pick up a perfectly rolled slot 5 that might win out.
- The Power Cosmic
- Cosmic Hood Medallion
- Good artifact choices include: GOK, advanced Meta, Doop Ecto, ACCoC, Tasky, etc
- Atlantis or maybe Asgard for relics
- Power Doop runeword
Rotation is straight forward and twitchy: lay down your mental AOE dot and lotus bleed, spam Kirisute Gomen (left mouse button for me), use signature on cooldown or as needed for spirit and defense, Typhoon every three seconds, and use Assassinate as you heavy hitter but only after hitting Psionic Projections to buff it to OP levels.
So: Psionic Assault, Falling Lotus, Typhoon, Projection into Assassinate, Signature, Kirisute spam while dots tick and everything is on cooldown.
You're going to be hitting Typhoon every three seconds followed almost immediately by Projection and Assassinate (four second cooldown). Keep your two dots refreshed and keep spamming Kirisute.
