My group feels that the d10 is a little too wild. So I devised an alternative method to be used when rolling for abilities and spellcasting. I see others have come up with alternatives, so this is just my contribution to the issue. This system:
- Has a slightly higher average than the 1d10 (roughly +0,25)
- Has a bell shaped curve that reduces the frequency of high and low rolls
- Caps the critics at 20
- Has a slightly higher percentage to give a botch (+0,5% with three botch dices) and it removes the lowest criticals (2-6 with three botch dices).
- Requires less rolls (for criticals and botches)
It's like this:
For a simple roll you roll 2d10 and take the average of the two, round up.
For a stress roll:
- the GM declares beforehand how many botch dices are expected for the roll (n).
- You roll 2d10.
- If the two dices give the same number and that number is n or lower, that's a botch. You then roll n-1 dices and for every dice that gives the same number as the first two, it's an additional botch.
- If the two dices give the same number and that number is higher than n, that's a critical. You sum up the dices.
- If the two dices give different numbers, you take the average, rounded up, as in the simple roll.
