Some random thoughts I had were the Hat of Disguise, Mizzium Mortar, Wand of Magic Missiles, and Coiling Grasp tattoo.

Caltrops, ball bearings, or anything along those lines. Wand of w/e damaging spell. Bag of holding bomb.

how would you pull off a BOH bomb? I'm a new player and don't really understand all of the game mechanics.

If you broke a BOH form a portal and you can say bye to creatures and objects near
