It's no good, $N!  No matter how many coals I put to the fire, it's just not enough heat.$B$BThere's only one thing I can think of that is hot enough to temper this key and it is the insides of the Legion's fel reavers.$B$BI've only ever seen one downed once.  I remember seeing its insides fuming, shooting fire and steam as it fell.  Take this mold and plunge it into a fallen fel reaver.  I recommend you get yourself some friends if you plan to take one down.
