I have a question about this part "A tie follows the Tie rules. E.g. The attacker rolls a d6 and gets 5. The defender rolls a d8 and gets 3, so the defender takes 5-3 = 2 damage." Does that mean you just roll the dice again? Or what would this rule be for ties, because there aren't any ties in the example?
If you see my writing weird, it's because I'm not that good with English, and I used a translator to ask this question.
