Then the GM use the stat x difficulty, A normal roll would be stat x 5. So Strenght 10x5 - Then you have to roll under 50 to suceed. And then we have the exp, one thing thats kinda cool is that you get bonus ep throu out the game on things you use. But the way to calculate it is harsh. To get better on something ( 1% ) you have to roll to fail the skill, and then roll a D3. If you suceed you get a flat 1%. So even if you uhm... suceed fail? you can get stuck with a flat 1% addition. (2/3)
