Thanks, JoRo. That's what I wanted to hear!
So, wood shields work great for defense, not so much as weapons. Since I'm supplying proper weapons to my lil guys, that's a non-issue.
I'm assuming shields also add to your overall armor, so it helps to use better materials in that respect, but I'm still struggling just to equip everyone in iron, so as long as the wood shields block properly, I'm happy.
What with bucklers being worse, what's the point of them? Why would I ever build a buckler instead of a shield?
