Throne and Liberty. AOE curse explosion. Wand/Staff.
The rotation i do is:
1. On 1 mob I stack 3 Touch of despair .
2. Followed immediately by Cursed Nightmare.
3. Once I see the mob sleep i cast Time for Punishment 1 more Touch, then Karmic Haze. (This will pass the debuffs to the other mobs, including the sleep).
4. Then Corrupted Magic Circle for additional curse.
5. And finally Curse explosion.
