The skill "Jack of All Trades" is a special case. It allows re-rolling of unskilled tasks. So, for instance, if I'm trying to do emergency repairs on the ship's artificial gravity generator and lack either "gravitics" or "engineering", I do so as unskilled. If I have J-o-T 2, I potentially get two re-rolls.
Dice mechanics are simplified from what we got used to on Tavern_Keeper, but should work well. As follows:
Dice should be in the format
(number of dice)d(die type)(modifier)
Separate rolls should be separated by commas or on new lines.
Example: 2d4, 3d6+4
.
Rolls
Experiment - (2d6+1)
(63) + 1 = 10
