You hear a deep thunderous boom, which must have come from the ruby! As it
continues to spin, it grows larger, gradually deforming to match the shape of
the belt. It descends, until it finally disappears into the molten metal. With
a final burst of cold air, everything solidifies, and gives no hint of its
previous liquid form.

Ruuben tells you 'CONGRATULATIONS! Few have ever possessed a creation such as
this, I hope you find it of continual aid in your endeavors. I know you will
do the Merchant's Guild proud.' 

Ruuben [merchant]: All hail Fuser!!! He has truly earned the rank of Master
Merchant, and built for himself an incredibly powerful toolbelt!
