Strange.
I assume you are correct, it seems to fit in the calculations.
Everywhere I look (on the Internet) it's a matter of additions and substractions. Not a matter of percentages multiplications. But that would explain it.
I you're right (and the more I think about it and the more I think you're right), it means what whatever scores you have on your primary attributes, if someone has 5 in his resist skill he'll reduce your % to hit to sh**. Even if you hit 200% to hit you end up with only 50% with your final chance to apply the status (-75%).
For a game that says itself to be a tactic one, it would be quite random... even punishing.
THANKS A LOT for taking time to explain this !!!
