(Roll High) Characteristic Saves in Classic Traveller

I don't really care for the roll under Characteristic value saves in a game where players always want to roll high. Classic Traveller already has a good system that insinuates what advantages high or low stats might give in a situation, the advantageous/advantageous DMs for weapon handling and experience. These mostly apply to the three physical stats which would be the most likely candidates for saves like this, though I can see Intelligence being used for psionic or magical effects. They would also dovetail nicely with the combat stunts presented here. Characteristic SavesWhen facing a situation where a player character's characteristics define the chances of their success rather than their skills define a TN for the PC to roll equal to or over. The DM table lists the Dice Modifiers that the Characteristic gives to the save, but other DMs relevant to the situation should be applied. Characteristic Value DM 1 thru 2 -2 3 thru 5 -1 6 thru 8 0 9 thru 11 +1 12 thru 15 +2
