Demonology Warlock leveling guide
Demonology makes your demons stronger and you tougher. 
Demonic Embrace adds Stamina, 
Fel Stamina and 
Unholy Power turn your Voidwalker into a real tank, and 
Soul Link at level 40 moves part of the damage you take to your pet. It is the safest Warlock spec, though it kills a little slower than Affliction.
Strengths and weaknesses
- Very hard to kill with Demonic Embrace, a strong Voidwalker and Soul Link.
Master Demonologist gives you and your pet a bonus that depends on the demon.
Demonic Sacrifice and 
Fel Domination save a fight in which your pet dies.- Less damage of your own, so fights take a little longer.
Talents by level
Level 10 to 30
- Demonic Embrace 5/5,
Improved Voidwalker 3/3 and 
Improved Health Funnel 2/2. - Fel Domination and Fel Stamina 5/5.
- Unholy Power 4/5, then Demonic Sacrifice at level 30.
Level 31 to 40
- Unholy Power 5/5,
Master Summoner 2/2 and 
Improved Healthstone 1/2. - Master Demonologist 5/5, then Soul Link at level 40.
Level 41 to 60
- In Affliction:
Improved Corruption 5/5, 
Improved Life Tap 2/2 and 
Improved Drain Life 5/5. 
Improved Curse of Agony 3/3, 
Amplify Curse, Nightfall 2/2 and 
Grim Reach 2/2.
Rotation
One enemy
- Send the Voidwalker, then Curse of Agony, Corruption and
Immolate. 
Shadow Bolt or your wand while the Voidwalker holds the enemy.- Life Tap after the fight, and Health Funnel when the pet gets low.
Two enemies
Suffering from the Voidwalker draws both enemies to it.- Curse of Agony and Corruption on both, then Shadow Bolt on one.
Seduction from the Succubus, from level 20, keeps a humanoid out of the fight.
Staying alive
- Soul Link from level 40 sends part of your damage to the pet.
- When the Voidwalker is about to die, Demonic Sacrifice gives you health over time, and Fel Domination summons a new demon quickly.
Fear, a Healthstone and 
Death Coil from level 42 buy time.

Stats, weapons and tradeskills
- Stamina and Intellect. Spirit matters little with Demonic Embrace. Shadow Damage matters more at level 60.
- The wand finishes enemies and saves mana, so upgrade it often.
- Enchants: Mana or Stats on the chest, and Stamina on the bracers.
- Tradeskills: Tailoring for cloth armor and bags, with Enchanting to craft your own wands.
