I'm playing Valheim Plus, I think this is the only mod I'm using, but I looked at wikia, it isn't up to date, but it says Flametal is vanilla. Are you sure about what are you talking? The version of the game is 0.212.9, while wikia is around 0.146.11:

So... IT IS vanilla, I think it's already in-game, so my question remains... Why I learned and why he didn't?
