Holy stuff, I just caught a bronze colossus in one of my cage traps. What the hell am I supposed to do with him now?
If you kill the colossus you get a heug statue amirite?
Did it kill anyone before hand? If it did then taming it would be a very bad idea and I would suggest trying to kill it somehow.If it didn't kill any of your dwarves though then try to tame it.
That works too, but really no matter how you are trapping them, you can avoid losing a dwarf by making sure to do it in the right way.Also afaik the traders don't care how they die, they blame it on you. Except maybe if they are directly killed by a monster.
