The most recent class addition is the Warlock, summoner of demonic Magic. The Warlock class in WoW can only be played by either Orcs of Humans. The Warlock will have access to all sorts of skills including the ability to summon Infernals, Fel hunters (melee support), imp (will attack at range, cast spells) and void walkers (does large amounts of damage but loses health slowly and he also casts buffs on you. Nice Walker). Also, since they made pacts with the demons they can also draw energies from other players so they can basically steal health and mana.

We were introduced to the Warlocks 'pets' in the demonstration and their pet interface is pretty easy to use. Each pet can be assigned a command, simply click on the pet avatar in the top left of the screen and issue commands such as passive, defensive, wait, follow, attack and dismiss. These can of course be hot-key activated if you so wish.

Pets are ideal for the Warlock because as your pet Imp attacks a target, your Corruption and Immolation sap at the target's health and the burn them to boot. All this time your Imp is working as a distraction while you stand back and weave your magic or use a spell such as Death Coil to steal health and boost your own. The Warlock class will not be able to melee on his own without a pet or skills sapping the target. Should you try it it's more than likely you'll end up dead. Other Warlock spells we were shown included Sleep which puts a target to sleep until it is attacked when it'll awaken and begin to attack. Soul Tap which takes a little bit of your life and gives it to your pet. Shane mentioned that Soul Tap can be dangerous because if you're health is low you could end up killing yourself as you transfer your last dribble of health over to your pet. He actually did this himself and we're sure it was his grand plan to show us how not to use Soul Tap.
