Jeweler graver behavior

Format: use graver object

Drills one socket into the item, if it has room for another and your jeweler level allows it.

Format: use graver object stone

Sets a stone into the next free socket. Only a jeweler can do this, the stone is consumed, and the setting is permanent -- an item never carries two stones of the same kind.

Format: use graver object clear

Tries to pull every stone back out of the item: a rough stone survives the extraction a quarter of the time, a cut stone half the time, a flawless stone always. A stone that doesn't survive crumbles to dust. Either way, the sockets themselves are left empty and ready for new stones.

Drilling the first socket is a one-way choice: a socketed item can no longer be enchanted, the same way an already-enchanted item refuses the graver. Only weapons, shields, body armor, helms, gloves, rings and earrings have socket slots at all -- neck, wrist, waist, leg, foot, arm, cloak and other clothing-type gear never do, and each socket past the first also waits on a higher jeweler level. Limited items, items that cannot be purged, and anything owned by someone else refuse the graver outright. See sockets for the full count per slot and what each stone does.

A graver can be bought at the jeweler's own shop in Midgaard.
