Repair Dice
The dice chain is d2, d4, d6, d8, d10, d12, d20, d100.
Resources
Resources use Repair Dice, and have an Interval. Every time the Interval's Time Pool expires, roll the Repair Dice. If the result is 1, the Repair Dice become one size smaller. When a d2 rolls a 1, the resource is exhausted.
Normal resupply means the Repair Dice becomes one step larger.
