Affliction Lock

Rotation:

• Haunt
• Bane of Doom
• Corruption
• Unstable Affliction, OR Drain Soul (when below 25% target)
• Shadowflame (only if in range)
• Demon Soul
• Shadow Bolt or Drain Life (preference)

Basically, using Demon Soul on cooldown is important, preferably with on "Use" trinkets. After that it is simply a case of keeping Unstable Affliction, Corruption and Bane of Doom up as much as possible, while casting Haunt on cooldown to keep 100% uptime on the debuff. After that, simply spam Shadow Bolt or channel Drain Life.
