Dispel refers to the general game mechanic of removing Buffs and Debuffs. All of these effects belong to a Dispel Type. Most dispel abilities remove effects from a specific dispel type, but in some cases they remove depending on a specific mechanic (for example, Luffa removes bleed effects).
Dispels can be resisted. In fact, there are two different types of resist-like effects:
- Resists (caused by spell hit and resistances)
- Fails (caused by what is commonly referred to as "dispel resistance")
Normal resists do only exist for offensive dispels and follow the same rule as any other spell. When a dispel is normally resisted, it does not remove any buffs.
Fails are treated differently. They are calculated per buff and can also occur when dispelling friendly targets. There is an innate chance that this happens (however, this might be a bug). In addition, dispel resistance can be used to increase the chance, such as from Silent Resolve. Due to fails being calculated separately for each buff, a dispel which would remove two buffs could eliminate one buff while retaining the other. On spell hit procs are not affected by fails. As such, a Dispel Magic (rank 2) can trigger a proc even though it fails at removing both buffs.

Dispels diseases and poisons. (Can spec into dispelling defensive magic)
Dispels diseases (outside of Shadowform), offensive magic, and defensive magic.
List of class talents that counter the Dispel mechanic
Note: The most common dispel-countering mechanic is dispel resistance; talents which provide it have a specific tag in this list. The remaining spells and talents have individual effects.
- Death Knight
- Virulence (Dispel resistance)
- Arcane Subtlety (Dispel resistance)
- Vile Poisons (Dispel resistance)
Dispel Fodder is the act made by any player when they keep up as many buffs as possible. This is done to prevent the enemies from dispelling all buffs, so that they'll need to dispel a lot more, i.e. a huge mana consumption and also a waste of time since generally any dispel spell will trigger GCD. Dispel fodder is also useful to save important buffs because the more buffs one has, the more time it will be needed to dispel all and also probability that the important buffs will be dispelled will be lower since there is no priority for dispel mechanics. For example someone wants to keep trash buffs up to save important ones like Heroism/Bloodlust.
