Seeing that both the oil of sharpness and a +3 weapon are both classified as very rare items and are on the same spots on both the arcana and armament treasure tables I think it was designed on purpose.
I think the oil of sharpness was designed so that you can turn a family heirloom, inherited regular weapon, or weapon of a rare type into a magic item.
My issue is why there's no oil of hardening for bludgeoning weapons.
it would be nice to have:
lesser oil of sharpness: +1
oil of sharpness: +2
greater oil of sharpness: +3
for blunt weapons, it can be; lesser, standard, greater gem of impact that merges with the weapon.
I had an awakened tree with a face that would eat magic items that were fed to it and spit out other, requested items of the same rarity.I have done stuff like this, but usually involves a temple and some sort of holy font or blacksmith fire.
