Hi Enhancement Shaman,

A change is coming next week to how Windfury Totem works. These changes have no impact on the Windfury Weapon imbue, nothing is changing with how that works.

For some quick context, in Shadowlands, Windfury Totem can only activate from main-hand auto-attacks, and causes a main-hand auto-attack swing when it activates.

The next build you receive should have Windfury Totem changed to work this way:

Main-hand auto attack interaction is unchanged, except for the miss note below.

Off-hand attacks can proc an off-hand Windfury attack. This is an actual real “auto attack”, which means things like Flametongue Weapon, or whatever other effects may activate from off-hand attacks, can now potentially happen from this bonus attack.

Windfury Totem extra attacks can no longer miss. This has very little impact on 2h users, as an Arms Warrior or Retribution Paladin almost never see a miss in their combat log, however dual-wield users have a high miss chance. In Shadowlands, this miss chance both applies to the chance to get the Windfury Totem’s extra attack, and the extra attack itself can then miss. Targets can still dodge or parry these attacks, they are just no longer able to miss.

Bonus bug fix: Enhancement Shaman who are under the effects of Ascendance can now benefit from Windfury Totem if they are auto-attacking from outside of melee range range with Windlash.

We will be monitoring any unintended side effects from this change, but this should help make Windfury Totem more valuable to more specs within the game.
