House of Music guild card states:
"Whenever you use the Tavern, you may also capture a monster from the Forest or fight a captured monster."
Witch's Hut location states:
"Use the ability at the Location of the King's Guard"
So, do I get to capture/fight a monster when using the Witch's Hut, and the King's Guard is at the tavern? I don't know if "use the ability" and "use the location" are synonymous. (Normally' it's irrelevant, because you can't separate the two ideas.)
This Q/A is related, but not the same.
