Shadow Priest: Rotation

Level 40–60 with Shadowform (projected)

1. 
   Shadowform always on; drop it only to heal. Unconfirmed
2. 
   Shadow Word: Pain kept up on every target that will live through it.
3. 
   Devouring Plague on cooldown; with Devouring Contagion it spreads when the target dies.
4.

5. 
   Shadow Word: Death at or below 20% health with Early Demise, or while moving if you can take the backlash. Unconfirmed
6. 
   Mind Flay as filler between everything else.
7. 
   Vampiric Embrace when the party takes damage.

Packs

1. 
   Shadow Word: Pain on each mob. Mana-hungry before Shadowform.
2. 
   Psychic Scream to scatter the pack while the DoTs tick.
3. 
   Power Word: Shield on yourself, then Mind Flay the one that comes back.
4. 
   Devouring Plague with Devouring Contagion, on the mob that dies first.

Cooldowns and emergencies

While leveling

1.

   Mind Blast to pull, from 30 yards.
3. 
   Shadow Word: Pain straight after.
4. 
   Mind Flay from 20 (22 with Wand Specialization) as the mob closes; it slows it. Watch your mana.
