Bag of Precise Essentials

A fabulously decorated pouch made from fine purple silks, drawn closed by a glistening golden cord. Whoever made this spared no detail and clearly had a taste for opulence. 

Once per day, someone may reach inside of this pouch to pull out exactly what they need. Whoever it is that is determining what they need is a total mystery but the player may use a bonus action to reach inside of the bag and pull something out. Before reaching inside, the player must roll a d20 to determine just how much they need whatever it is the bag is about to give them.

There is a note on the bag containing various different scribbles in numerous different handwritings that seems to list things people have pulled out of the bag: arrows, a health potion, a giant rat, three goblins, a magic greatsword, a pint of ale, a dirty sock, a scroll of ray of frost, a map of the city, 300 marbles that fell on the ground, a powerful magic ring, a very confused orc... The list goes on and on until the writing is too small to read.
