I'm sad the d30 isn't in the list.
I voted d20 and d8. I love both of those so freakin' much. d8s are maybe the most perfect dice ever. d20 is great too, and I love my d20s, but my d30 is very special. I have whole random charts tied to 1-30 rolls.
I love my d60 as well. So great for tracking time and deciding on random minutes. Alongside my d24, I always know what time it is in the campaign, or exactly when something went bump in the night.
And that "Salable Magic Items" table? Where it says "days to find a buyer?" I up each of those days. instead of 1d4 for Common, I use 1d5. Instead of 1d6 for Uncommon, it could take up to a full week, or 1d7. For rare items, I use 1d10. And for Very Rare, I use 1d14, or a fortnight. There are other cases where it might take time to find something. Depending on how difficult it is to find something, but the players are willing to spend the time, I use those same scales – up to a full working week, up to a full week, up to ten days, and up to two weeks. Rolling two dice for such things would be inelegant – you'd never find something in just one day! No, gotta use those non-standard dice!
