In World of Warcraft, the following classes are able to cast spells:
Mana, a magical power resource used when casting, is available to all of the above classes. Death Knights can also be partially classified as casters due to some ranged abilities, however they use runes and runic power instead of mana, and, like hunters, none of their abilities scale with spell power.
In Cataclysm EditThis section concerns content exclusive to Cataclysm.
The Cataclysm expansion changed the hunter's resource from Mana to Focus. Hunters previously used mana for their abilities, but were generally not considered casters because of their focus on physical damage, and their abilities did not scale with Spell power.
Other meanings Edit
Occasionally, the term caster is used contextually in a more restrictive sense than the one offered by the dictionary definition above:
- In relation to large raid dungeons, i.e. Molten Core, 'casters' often refers to players that do not need to be within melee range of enemy targets and which are reliant upon mana (and thus have specific requirements with regards to mana regeneration).
- In relation to smaller dungeons, "caster" is usually used synonymously with nuker, typically mages or warlocks, since other classes with spell casting abilities would be referred to specifically as healers.
- In relation to PvP, a "caster" is often synonymous with a character wearing cloth armor and relying on spells as their primary damage capacity, namely mages, warlocks and priests.
- In relation to PvE, a "caster" is often synonymous with a magic-wielding mob, usually singled-out because of their low armor class, high damage potential and difficulty to tank, as in "Target the casters first."
- In relation to Hunter pets, certain tameable beasts (those with a mana bar while still wild) are sometimes referred to as "caster pets". These pets have higher intellect and spirit, and lower health, armor, and DPS than most other pets — and as such are regarded by some as inferior to other pets.
