Potion, very rare
This iridescent, slimy oil is said to have been extracted from the brain of a mind flayer. The oil can coat one melee weapon or up to 5 pieces of ammunition. Applying the oil takes 1 minute. For 1 hour, any spells using psychic damage combined with the weapon (such as psychic blades) are granted an additional +d8 to their damage. Furthermore, once a coated melee weapon applies this damage for the first time, additional standard attacks with the same weapon are granted an additional +d4 to their damage, as the oil retains some of the psychic energy from the spell. This effect also expires an hour after application.
Notes: Bonus: Magic, Damage, Buff, Combat, Consumable
