if you macro detox as in /use detox. it says you haven’t learned the spell even though the spell works fine on its own
The issue seems to be related to there being two Detox abilities, one is locked in the Brewmaster spec and for some reason the game is trying to use that in a macro instead of the learned Detox spell for MW.
I’m having the exact same problem, instead of getting the Mistweaver Detox we’re getting the Brewmaster one which uses Energy instead of Mana, rendering our macro useless.
I can’t find a way to select the Mana Detox ability instead of the Energy one unfortunately.
Seems to work fine for me with this macro:
#showtooltip
/cast [@mouseover,nodead,exists] Detox
