Warlock is one of the most popular classes in WoW, mainly because they seem to be able to do almost anything: easy solo leveling, tanking with their pet, bursting high DPS (damage per second), and using their annoying DoT (damage over time) to own virtually any PvP match. However, there are several WoW Warlock leveling guide tips that you can use to boost your leveling speed significantly:

1. Your Race Selection

There are 4 Alliance races and 5 Horde races that you can pick to play a Warlock. That is plenty of options, nevertheless, there are a few races that can give you some advantages in some particular areas. Listed below are the races:

Alliance

• Gnome: if you like cool appearance, naturally Gnome isn't an option. Nevertheless, they do come with increased intellect, which could provide you with higher mana pool and spellpower.

• Human: possess Escape and Stealth Detection; they are invaluable abilities in PvP. They don’t possess any particular abilities to improve leveling speed though.

Horde

• Orc: if you love to play with your pet a lot, choosing Orc can increase the damage done by your pet. Orc also can resist stun to some point.

• Undead: can remove sleep and charms. These abilities are mostly useful in PvP.

2. Selecting Talents and Abilities

As usual, there are 3 talent trees to choose from and all of them demand different playing style.

Affliction Build

Your main assets are Fear, Drains, and the infamous DoT spells. Your pet won't be as strong as a Demonology warlock's pet, but it only need to buy you time until the enemy dies from your DoT spells. The following are several important talents and abilities in this build:

• Unstable Affliction: a high damage DoT spell with extra "bonuses" for anyone fool enough to dispel it.

• Shadow Mastery: improve your shadow damage by 25%.

• Potent Affliction: increase all periodic Shadow damage you deal.

Demonology Build

You have high damage spells, strong pet, and can turn yourself into a demon. Below are several essential talents and abilities in this build:

• Metamorphosis: you change into a demon for 30 second and get various power ups.

• Hand of Gul’dan: summon meteor that made surrounding enemies to be weaker against your demons.

• Immolate: instantaneous damage spell with DoT after it.

Destruction Build

Similar to a mage, you will burst huge damage spells to eliminate your enemies. Here are some essential talent and abilities for this build:

• Immolate: deliver instant fire damage that followed by DoT.

• Chaos Bolt: send chaotic fire at the opponent.

• Conflagrate: consume immolate effect on the enemy and deal instant damage.

• Incinerate: burst fire damage with some additional damage if the target is affected by immolate spell.

Despite the constant adjustments in Wow, Affliction warlock is still the most popular choice. It's best to stick to the Affliction build for quick leveling. You might not burst high damage right away, however, you have high survivability and will never run out of mana.

3. How You Level Up Your Character

In the normal server, I don’t know any other efficient way to level up your Warlock aside from questing and going through dungeons. If you can take and finish several quests at the same time whenever possible, you already on the right track. Dungeons can come occasionally for some additional XP and gears.

From the 3 WoW warlock leveling guide tips that I've mentioned, tip #2 and tip #3 are holding the most crucial part in your leveling speed. Take Affliction or Demonology build as I'm not recommending Destruction build for fast leveling. Also, make sure you know the most efficient way to accept and finish several quests at the same time whenever possible.
