Tavern Riddles!

The hooded stranger across from you has barely spoken all evening. Then, without warning, he slides his tankard aside and leans forward, a faint grin appearing beneath the shadow of his cowl.

“You look like someone who enjoys a puzzle.” His fingers drum slowly against the table. “Solve mine, and perhaps the next drink is on me.”

Tavern Riddle

I follow you wherever you roam,
Through castles, caverns, and places unknown.
I shrink when struck, yet grow when restored,
And when I am empty, your journey is floored.

What am I?
