*0.1 Curse of the Elements (if nothing similar is already on the target)
*0.2 Bane of Havoc (if there is more than 1 target)
*0.3 Demon Soul (if Bloodlust is active)
1. Improved Soul Fire buff
2. Immolate
3. Corruption
4. Curse of Doom
5. Conflagrate
*5.1 Shadowflame (if in melee range)
*5.2 Shadowbolt (if Shadow and Flame or Critical Mass is not on the target)
6. Empowered Imp Soul Fire
7. Chaos Bolt.

How does one Demon Soul as destro?

no use of fel flame to keep immolate on the target all the time? Seems to me that recasting immolate is a DPCT loss over fel flame.
