I happen to have a D12 and D6 just here…
OH yeah, 12 whole sides princess.
6 weeks, minimum two edges a day is your result.
Each unauthorised ruin will add an extra edge required for the next 5 days.
But if you manage 7 days without a ruin, doing TWICE your minimum edges (so four a day) you get to knock a week off your total.
Cum, even once, and it goes back to the full amount.
Good luck sweetie!
