Auril crashing from the ceiling?!

Big DnD finale collab with sir https://www.artstation.com/quinnnn
We're playing in a Rime of the Frostmaiden campaign and made it all the way up to her tower, we crashed the place with a galleon ship that came from a Robe of Useful Items patch, and she later came landing down on top of it.
then proceeded to beat our asses shortly after.
