We were pondering this card and how the bag might conceivably be lost, according to the rules.

It "may not be taken by a character's special ability or spell."

So that would definitely argue that the thief and the Acquisition spell can't take the BoH.

A little more vague for Gust of Wind. That isn't taking the bag -- but that is taking it away, so probably that wouldn't work. Opinions?

I thought instead that compiling a list of ways the bag *can* be taken would be easier.

1. Kill the character and take his stuff. (This would definitely work.)

2. Toadification (because that causes the character to drop the bag, and that would definitely work).

3. I'd think the tinker imp could teleport the bag away. As could that obnoxious whirlwind card, I guess?

4. How about the Tricks and Treats card, hmm? That's not a spell nor a character's special ability.

Those look fine. There is an Enemy, Trickster I think he's called, that when you defeat him, allows you to take an Object from a character in the same region IIRC, that's a nasty one against the Bag. Shatter Spell destroys the Bag and works (again IIRC). Gust of Wind and Whirlwind would also work.
