We used to roll a a 1d6 for the ten's digit, 1-3 is 0 and 4-6 is 1, and then the 1d10 for the one's digit.

So a 1d6, 1d10 roll of 3, 8 would be an 8. A 5, 8 would be 18...6,1 would be 11. So a Nat 20 would be 1d6, 4-6 and a 1d10 thrown a 0.

We played Palladium, we liked throwing dice. And when there was a critical parry to be made or some other high value roll, we could roll one of the dice first and to see how big of a chance there was to succeed with the second roll. So if I just got whacked big time that could kill me and they rolled an 18 or something, then I could roll my 1d6 first to see if I even got into the teens. If I did, then there was a bigger drum roll for the 1d10 roll to see if I parried.

I wonder if the odds were better that way or if we were fooling ourselves.
