changes:
added a set difficulty feature. Difficulty levels for rolls variy from 1-10, with each level being multiplied by 25 to determine the actual difficulty.
players have fatigue in each attribute equal to their stat. Whenever they fail a roll, the difficulty goes up by 1 level and their fatigue decreases in the attribute they used by 1. For each level of fatigue below 3, they take a penalty of -1 from their roll. If they hit 0, they can no longer attempt rolls of that attribute.
added critical success at 50 beyond difficulty and critical failures at 50 below. Critical success grants a bonus and critical failures give an additional negative event or debuff. If you crit fail, you can’t try again with that attribute for this encounter regardless of fatigue.
after testing, I’ve found that this system works fairly well for scaling difficulty of encounters. If a player can’t beat something with one stat, they have to use their head and find another way around. Test scenarios included moving a heavy object and scaling a cliff. When fatigue became too high for one player in the first one to try and move the object, the player elected to destroy it. When the same was true for the cliff, they decided to stack objects at the base of it to boost themselves.
