Marvelous Magic Marbles

These bags of magic marbles have 20 marbles when created. They can be
scattered on any flat surface forcing anying who steps on them to
make a balance check DC (20). They each also have the one spell in
them. They can be thrown at a target as a ranged attack, if
successful hit is scored the spell inside is released. Though each
time a marble is used in this way the balance DC is lowered IE: 20
marbles = DC 20, 17 = DC 17, 7 = DC 7 and so on. Placing the bag 1
foot away from a marble will force them to roll back into the bag.
Roll on the following chart to randomly create a bag of these. Each
roll adds 5 marbles to the bag so rolling four times is required for
a new bag. For a bag found in a dungeon or on something the PC's have
slayed roll a d10 to see how many have been used up. Save DC for a
thrown marble is the normal save for the spell of that level +2.
