This table definitely needs work ... but we'll try it as is for today.
Here is the idea.
You roll checks against your various abilities: wisdom, strength, dexterity and constitution.
To start with, the table above is completely blank. When you miss a check, the amount that you miss it by creates random possibilities. Thus, you make a wisdom check, you miss your wisdom by four, it creates four of the above possibilities on the list.
You accumulate increased chances of getting something by missing your ability checks. Miss a total of 20 on your ability checks, and the table is completely filled out.
For every ability check you miss, you roll once on the table.
Let us say that you miss ALL four of your abilities by 1 point. Let's that creates item #6, #11, #15 and #19.
Because you missed on all four abilities checks, you roll on the above table. If all four of your rolls do not hit any of the numbers described, then you've succeeded despite your errors.
