Depth of Alchemy

This Ring can be only be destroyed in a particular way.

Now, I hid Golem's Ring in the handle of a weapon. When you kill <HFFFA7272>40 Metal Golems<HFFFFFFFF> with this weapon in <HFFFA7272>the East Entrance of Windrill<HFFFFFFFF>, the magic of Ring will vibrate until it is finally destroyed. It is a hard task, but there is no other way. Do this for me.

You might think we can just throw it away but it stayed in Seena's store for a long time, so we have to destroy the Ring itself. I don't know who did this kind of evil…….
Anyway, Kill <HFFFA7272>40 Metal Golems in the East Entrance of Windrill<HFFFFFFFF>.

Show me the weapon. The Ring isn't destroyed. How can that be? Wait!
