Question about WF wep + totem

Does WF wep stack with WF totem. They seem like they do, but do they? WF totem giving 10% chance at extra AA, WF wep doing 25% x2 set damage hits based on AP. Seem completely different, and im getting the WF totem buff while its down.
Anyone know?

They are two separate procs. Windfury Weapon can not proc Windfury Totem because Windfury Totem can only proc off Auto Attacks, but Windfury Totem’s proc CAN trigger Windfury Weapon if it procs an extra Main Hand Auto Attack.

Example: Doomwinds Leggo grants 100% proc chance and damage for Windfury Weapon, but does not affect Windfury Totem because Windfury Totem is just a free auto attack.

Fun fact when we could grab Windfury Totem as a PvP Talent in Legion it’s affect was Windfury Weapon, but at a 40% chance to proc and hit three times. You could combine this with Legion’s Doomwinds Artifact ability to do some nutty damage.
