WoW Retail, Over-Powered Spellsteal Buff (Mage) (Patreon)

(EDIT: According to Patreon Ryan this buff now only lasts for a few seconds outside of an instance, making it only interesting for snapshotting effects)

Older Patreons will know there is a recurring bug with buffs which award an increase damage for certain classes of damage specifically . These can sometimes be spellstolen by mages for gamebreaking damage for short durations. Early in BFA there was a buff I discovered which literally allowed the player to one-shot raid bosses, before it was fixed.

I found another example of this in Serpentshrine Cavern. Around the boss Leotheras there are several "Greyheart Nether-Mages", each of these mobs has a strange self-buff which seems not to show up in any databases. This buff can be spellstolen. This is supposed to award 50 damage for arcane, fire or frost damage, but in fact this increases damage by 50%!

Unfortunately, although you can have one of each (ie 50% damage increase to arcane, fire and frost spells) you can't stack multiple versions of the same buff. However, it does survive through a hearth or port, meaning you can use this in raids (or pvp for that matter). Spellsteal's duration is only 2 mins-however that 2 mins would be enough for a mage to do a record parse. if summoned to a boss. Additionally, as players increase in relative power raid encounters are increasingly shorter duration.
