Hephaestus hammer boon

From An Open 3k Wiki

This boon will increase the Durability of your wielded weapon by a lot, making it basically unbreakable.

This is the message when the boon is granted:

<wizard> takes up Hephaestus' hammer and brings it down upon the anvil of
time.  Terror takes hold as silence surrounds you and time stands
still.  Blinding blue sheets of energy fly from the point of impact as
time lurches forward once again. You stumble slightly as the shock of
the sound wave reaches you.

A brilliant blue light engulfs your weapon.  It pulses with renewed
power in your grasp.
