Bag of Monster Summoning

When you use this bag, it will summon a hostile monster adjacent to you which will attack you and your companions (and, potentially, anyone you are in combat with). The DM selects the monster at random, of a CR which is half your level, rounded up to a whole number (level 1-2: CR 1; level 3-4: CR 2; and so on). The bag can only be used 3 times before it disintegrates.
