Ars Magica stress die
Any chance we can have an Ars Magica stress die in the die roller?
An Ars stress die is a d10. An initial 0 means a botch check must be made -- the botch check is some number of d10s looking for more zeros, which depends on the situation, so I wouldn't have it actually check for a botch. If there is no botch, the die roll is a 0.
If the die is 1, that means to reroll and double the result. Two 1s on a roll mean 4x, then 8 and so forth. If a 0 is rolled after any number of 1s, it counts now as 10.
Any other initial roll counts as its value.
There are a bunch of Ars games out there, which having this die would help.
