Red Garnet Salvage
From Drunkapedia
Chips of red garnet material salvaged from old items.
Apply this material to a treasure-generated weapon or magic-casting implement to imbue the target with Fire Rending. Fire Rending gives the weapon the ability to make its opponent vulnerable to fire attacks. The amount of vulnerability depends on the attack skill of the wielder. This effect does not stack with Fire Vulnerability spells.
Uses Weapon Tinkering skill to apply.
