An Abacus made of strange wood with six rods in it, each with 30 small beads on them, 10 of bronze, 10 of silver, and 10 of gold, in that order. On the frame where each rod ends there is an animal carved into it's surface. They are, in order, a bull, a cat, a bear, a fox, an owl, and an eagle. When ever a character holds the Abacus, the beads move on their own to certain numbers, which intelligent characters should be able to deduce are related to their abilities. Bull is Str, Cat is Dex, Bear is Con, Fox is Int, Owl is Wis, and Eagle is Cha. IE if a character has 12 Strength, then the ten bronze beads and two silver beads will stack at the bottom of the Bull rod, with the rest sticking to the top end of the rod. The abacus does not take into account bonuses from potions or gear (like a potion or belt of giant's strength). 

No amount of shaking the abacus will move the beads, but if the character firmly grasps a single bead they can move it to the other side, but a random bead move in the opposite direction (Roll a d6, 1 is Bull, 2 is Cat, etc. If you roll the rod that was moved, the bead will fly back to it's original position). This will affect the character's stats accordingly, and they can move as many beads as they like so long as they are firmly grasping the abacus and the bead they want to move. Other characters can not move beads when another character is holding the abacus, and will find their fingers slip off the beads no matter how firmly they try to hold them.

If a character moves the beads such that there is only 1 bead at the bottom of any stack, they will find moving beads extremely difficult and would need to succeed a DC 15 Str check to successfully move a bead, with the exception of the bead opposite the 1 remaining bead, which can be moved as normal. If the last bead of a rod is successfully moved, the character will drop dead immediately. If the character is revived, there stat points will be randomly distributed (DM can determine how, rolling d6s for each point until they are all distributed is an option) and they will be unable to move abacus beads, their fingers slipping anytime they try,
