You may not have noticed, but I'm pretty big, as far as orcs go.
I make sure that my two pals here don't get into too much trouble. They're small, and they don't have a big shield like me. I'm big, and I can handle a few monsters hitting me! Plus, if I'm careful, I can usually get them to hit my shield instead!
I can protect you, too. Come on, let's go practice for a bit. I'll make sure the enemies attack me, and not you.
