Yeah, my macedwarf champion gave the titan a boubou on his leg, and it collapsed in pain. A crossbowdwarf hits both its lungs, a human caravan guard hits it with an arrow, the maceman bashes its head in.
Total dwarven casualties: None
Total human casualties: None
Total traps used (he was killed 3 squares from my trap wall): None
Animals killed (I surrounded my trade depot/ entrance steps with war dogs): None
I was waiting for a semi or full megabeast, but now one has come I'm a bit dissapointed. Still, a nice thing for my macedwarf to have on her CV.
EDIT: OMG. Just had first dragon. Ordered dwarves to stay inside, but for some reason the same macedwarf who killed the titan casually wandered out. Resisted a firebreath, hit the dragon in the tail, stunning it. Then (this is the bit I don't get) he seemed to kill the dragon. In one hit. Without wounding it, or making it faint. Just killed it, instantly, in one hit. Now that was quite something. No damage or casualties (well, the dragon injured a stray war dog and a stray bull in its fire, who subsequently died when they hit traps, but I don't think that counts) in 2 mega beasts, and they both go on the CV of this macedwarf (who also apparently killed 5 goblins in the last siege). Do previous kills make dwarves stronger?
Now "Daskot Snakelashed the Armored Urg-". Hmm, is there anyway to see the rest of the name? She's also got 2 more names on the unit screen, and I can't see what job she's doing. Also, I'm giving her my artifact iron mace.
Oh yeah, and it melted some random zinc I had lying around.
