From all the training my initial macemen had, three of them took on Legendary status and became Champions. I never really needed them for military work, so they continued to spar and grew in experience with Shields and Armor. Not to mention gaining nearly all attribute levels!
Now, recently, my lava channel ran into floodgate troubles (flipping the switch repeatedly is NOT a good thing; lava drained all the way back to the lava fields and I had to rush to kick-start it again). So I had to finally bring my military into action to prevent the trolls and a deadly goblin bowman from ravaging my corridor leading to my seige engines.
One champion came rushing down and took on the entire squad of trolls by himself, only taking a few bumps and bruises. But the bowman managed a few lucky shots and he bled to death. A second champion avenged his death quickly.
My channel still wasn't operational and the next squad of trolls and goblins were coming. That second champion took it upon himself to engage them all in the tiny one-tile channel, smashing troll skulls left and right, stomping goblins when they decided their grunts weren't doing so good, and blocking every single arrow that flew towards him. He came out of there with only a yellow wound and several bruises, where the lava finally flowed to clean the blood (and useless leather/cloth articles).
I wish the rest of my military were this...militant in sparring and getting better. :/
The seige was quickly broken after that!
