I wish they'd create a D12 substitute for the fortune/misfortune dice. It gets a bit tedious when you roll upwards of 10-15 dice sometimes and its time consuming to subtract that many results from each.
A D12 with 3 blank sides, 4 hammer results, 2 boon results and 1 of each double hammer, hammer + boon and double boon would be almost the same. the only significant difference is the double boon/bane result has a 5x increased chance of occurring. But the you can switch two dice for one. I'd like that.
