I couldn’t find it in the book but what do you roll when you bash someone with your shield? In Burning Wheel Gold on pg 555 it list the weapon stats for a shield, but I couldn’t find what skill to use for that.
Also, block says to test your weapon skill, but what if you have been disarmed or otherwise don’t have a weapon? Would you roll brawling/boxing? It doesn’t make sense to me to roll those if you are just blocking.
