Yes, he can be caged and tamed. He doesn’t vanish: a knocked-out native comes round after a while (about 2.5 minutes on the ground, up to 5 on your shoulder), gets off and walks back to his village. A save keeps the time he has left, so after loading he may wake up almost at once. Build the cage close to the village before the fight, or carry him straight to it.
Maybe you misunderstood me? I wasn't referring to a simple native, but to the boss: their leader, the black, horned mask, drops his special loot, is located in the north of the island. While I was waiting for your answer, I already tried to enslave him by putting him in a cage that I built not far from his village. As a result, he disappeared into this cage after a while.
Killed her alone
Fought her with lethal weapons, finished her off with a club
Aaaand yes, she has a few
I fought her a few more times, alone and in a crowd, and tamed her twice to test it out, and as long as you finish her off with the club, it should work
Maybe the cage is bugged? idk
her fur color changed out of nowhere, I liked it white way more :'c
