Death knight is world of warcraft’s first hero class. It is a name shared by several organizations of powerful necromancers. These orders share a few things in common, including riding horses with horned skulls and many of the same abilities. Playable death knights, however, are specifically death knights of the Scourge. A death knight is a type of fictional creature that appears in a number of role playing games.The death knight can be considered a hybrid melee class that combines damage ealing and tanking, somewhat akin to Warriors. They wear plate armor and are able to dual-wield or use two-handed blade weapons. Like druids, they tank without shields. Their tanking mechanics involve high armor and a high chance to parry. Death knight tanks depend on a combination of high damage abilities and high threat abilities, such as Decay and Death and Rune Strike.
My wow account is a death knight which has three talent trees that enhance certain aspects her specialties. However, the differences between the trees are not as clear-cut as those of other classes, both for PvE and PvP environments. Obviously, death knights can tank or deal damage regardless in which talent tree they specialize, although a careful talent selection is still required to bolster their preferred role.
Every wow account has its special ability. You should know that Blood enhances the death knight's melee abilities and damage and vastly improves the ability to heal itself. Blood also provides healing utility to party and raids and has some very useful buffs and debuffs that the death knight can cast on others. Frost enhances melee abilities and focuses on increasing both AoE and single target damage. It also enhances or provides useful emergency damage mitigation abilities like Icebound Fortitude. Unholy enhances the death knight's diseases and damage over time spells, making them effective at AoE DPS.
The death knight class has its own special weapon enchanting ability called Runeforging, which replaces the need for conventional weapon enchants-- Rune of the Fallen Crusader for example. And it is a very unique damage-dealing class in that their damage is dealt by both melee abilities and spells. If you want to begin your wow with the hero of death knight, you will have a lot of different choices on farmer100.
