Magik Oil

This magik oil can be socketed on any item you don't mind getting oil stains on. The slow drip of oil from its never-closing spout imbues the item to which it is attached with magic, rendering the item much more durable. Metal can't be corroded by acid and wood & clothing cease being flammable. Strong magic, such as that from a 6th-level spell or higher, can overcome this enhanced resilience. If socketed on a weapon, that weapon's damage becomes magical. If socketed on armor, the oil lubricates the joints, removing any disadvantage on Dexterity (Stealth) checks the armor normally imposes.
