Thanks for the answer.
It's a bit weird. How does the minotaur lose its greataxe and get a battleaxe while running after Janira ? And why is it broken ? Indeed, Janira doesn't know the spell Shatter and she gives away her Scroll of Shatter to the PCs.
Logically, the only difference between the minotaur before and after should be its hit points. What do you think ?
Thanks
EDIT : Sorry, I made a mistake. Janira keeps her Scroll of Shatter.
