Hmmm. 4x Tama-hagane is way too cheap for these. Probably requires at least 1 adaman or relic steel.
EDIT: Relic Steel has a similar description about "a manner taught in a land far to the south" It isn't listed here on this site, but it is on the auction house. I don't know how to get it.
Does anyone know what monsters drop these? I've heard that King Arthro and the Roc drop them, as well as some of the higher level Burning Cicle fights. Are there any others?
