This spell is used to add a weapon to the riftwalkers weapon store ('gem
weapons' to list your available weapons). The weapon needs to be in your
inventory, and not in your keep list. Once your weapon is consumed, it will
remain in your weapon store for as long as it has energy. Unfortunately while
your entities make use of your arsenal, the entity will drain the weapons
power. Hence the more powerful the weapon you use, the longer it will last.
Spell chance effects the weapons maximum energy value.
You will be prompted [Y/N] before the spell completely consumes the weapon.
WARNING: The weapon will be PERMANENTLY DESTROYED!
Syntax: cast consume weapon at <weapon/shield>
