I read about all the things requireing alchemy to craft the different katana weapons, but note the Sakurafubuki, is an unstable weapon, providing its own alchemic catalyst, calm as a pond, violent as a typhoon. There is a post for the above noted katana that explains its meaning, and is such the derivent for my thinking in thtis way.
OK you guys are driving me crazy why would you post anything if you dont know the info someone said Alchemy i was going crazy trying to find it because i do a lot of alchemy when in actuality it is a Smithing recipe level cap 73 Fire Crystal + Steel Ingot + Sakurafubuki= Muketsu
This is a Smithing synthesis result, trivs somewhere in the mid-50s I believe. As such there is a +1 with a little more damage, little less delay. I'd look up the recipe but I'm feeling lazy. Check mysterytour if you're curious.
