Death Knight is a new class for Wrath of the Lich King in World of Warcraft. It is World of Warcraft's first Hero class, is not your average adventurer seeking to prove his or her worth on Azeroth's fields of battle. It is a good character that can help players gather more World of Warcraft gold, items, equipments and WoW experience (WoW power leveling) easily. Here, we will introduce some abilities of Death knight.

Abilities of Death Knight

1. Presences: Much like Paladin Auras or Warrior stances, Presences will be powerful one-at-a-time self-buffs that will probably determine whether the Death Knight is taking on a Tank or DPS role in the group.
2. Blood Presence will increase the Death Knight's DPS and provide a small healing effect when the Death Knight is hit. It means players can save some WoW gold to buy other useful items, not food and drink.
3. Frost Presence will increase the Armor and Threat of the Death Knight.
4. Unholy Presence will provide increased attack speed and decreased global cooldown, and is being billed as the PvP presence. PvP is the best way for players to collect experience which help players to achieve WoW power-leveling quickly.
5. Death Coil: It will not fear like the Warlock version, but will act like the WC3 version also used by Death Knights in that game, damaging enemies or healing friendly undead targets. It looks like Death Knights are still very useful in a team or group. It can bring members more loot and rewards, of course, players have a chance to finish WoW powerleveling as soon as possible.
6. Army of the Dead: This ability will temporarily summon a small army of Undead that will fight for you. It will apparently be channeled, which makes me think it will be closer to an AE attack like a Druid's Hurricane than an actual pet ability.
7. Raise Dead: This will raise an actual nearby corpse, including one of a fallen ally (even in Arenas) to fight for you as a Ghoul. An ally so resurrected will have the option to control their character as a Ghoul. Ghouls will get abilities to cause diseases, stun, and fear among other things, but it seems like they will be temporary pets all the same - at least, I assume PCs will eventually be allowed to resurrect rather than stay slaves of the Death Knight.
8. Grip of Death: Pulls the enemy toward you and forces it to attack you (Probably a taunt effect, though It'd be great if the pulling effect works in PvP).
9. Blade Strike: Attacks the target and applies a disease.
10. Blood Strike: Deals Damage based on how many diseases are on the target.
11. Chains of Ice: Roots a target, then applies a snare that lifts gradually until the target regains full mobility
