EDITED OUT so people can not exploit this bug.

This is a bug indeed. I'm gonna fix it.

And Is there different keystone drop in Blackfire?
The green keystone, the blue keystone and red keystone?
I've got the green one, but never seen the other two color style of keystone.

The blue one drops from floor 20 onwards.
