Variables
To represent the chaotic nature of our world we use variables to help determine the outcome of events. These (v:X) are modified by attributes, buffs/debuffs, situational adjustments, abilities, equipment, magic, and skills.
(v:4) (v:6) (v:8) (v:10) (v:12) (v:20) (v:100)
A specific check will show the variable range and whatever bonuses or penalties are added to it. For example (v:20 Strength) is 1-20 +/- Strength.
