Bronze reward will never reward anything of note, but silver and gold definitely do.

Odin levels up every time he is defeated, and levels down every time Zantesuken goes off. Silver and gold tier rewards scale based on his level.

I have never gotten gold, but I also have never seen less than 1 mantle from silver.


By contrast, Behemoth silver rewards 1 horn, and gold rewards 5 horns.
