The Wild Magic Grab-bag is a small brown sack with light blue accents. It contains 50 unique pieces of magical ammunition. The rounds reshape themselves to fit whatever weapon they are loaded into. When you load a round into a weapon as a bonus action, the next attack you make with that weapon will have a random magical effect that the DM determines by rolling on the sorcerer's wild magic table. If you miss the attack, the DM will still determine an effect, and decide weather it will apply to a missed shot or not. Weather or not the effect is created, the round that can create it is consumed. All of the spent rounds are magically replenished after you finish a long rest.
