The Attributes used are what were supposed to be in place for my homestuck rp. To generate them you use 2 d10 (ten-sided die). One will be your "high" die the other is your "low" die you roll both and that is you score for said attributes. Say the score is 57. For an ability check you would subtract 57 from 100, and the difference is how high you need to roll(minimum) to succeed( in this case, it would need to be a 43 or higher to  achieve success.) Certain situations , However, would need a table to more accurately Show an outcome (this is done with a D20 [twenty-sided die] and the table below.)

Like This:
Atrib. score     Modifier   
01-05                 -5
09-10                 -4
11-20                 -3
21-30                 -2
31-40                 -1
41-50                  0
51-60                 +1
61-70                 +2
71-80                 +3
81-90                 +4
91-99                 +5
(doesn't 
go to 100
as I think there should
at least be SOME chance of failure,and that is how high the dice go.)
