Demonology Warlock

Single Target Rotation

1. Implosion (see Note 1)
2. Grimoire: Felguard on cooldown
3. Summon Vilefiend on cooldown (see Note 2)
4. Demonic Strength on cooldown
5. Call Dreadstalkers on cooldown
6. Hand of Guldan (if >4 Soul Shards)
7. Demonbolt (if > 2 stacks of Demonic Core)
8. Hand of Gul'dan (using 3 Soul Shards)
9. Shadow Bolt

Note 1: Only cast Implosion when you have at least 3 Wild Imps up.

Note 2: The cooldown Summon Demonic Tyrant should be cast right after Summon Vilefiend, and it will be available again every-other time.

AoE Rotation

The Single Target Rotation should be continued even when fighting multiple targets. You can swap Summon Vilefiend for more available Soul Shards for Hand of Guldan, which is mostly effective in quick-to-die trash scenarios.
