Shared in the temple study, found in a box on the shelf.

This artifact is for active usage, by advanced users. It will light a flame of hell-fire in your dantian - lower abdomen field.
'Warning
The process once started will be very difficult to halt, do not put this ring on your finger unless you are prepared to maintain and control the flame 24/7.
The purpose of this is to burn away your karma from inside, letting the fire spread inside your body. You will feel physically hot and may experience physical pain in any part of your body. The flame burns your karma, letting it loose in an unpurified body will result in a situation out of control.

It works well in combination with qi gong practice or double lotus position meditation. The purpose of this artifact is to share the method of igniting the flame, it is not a mere trinket.
Use this to get rid of your last difficult karma which you couldn't budge using other methods.

As any artifact, you can make a copy and store it, then put it on your finger to active at a later time.
