Oil of Sharpening
A weapon oil that makes a telling blow of a lucky one: five uses, an hour apiece
An oil for the edge of a weapon, magical or not. It does nothing to make a blow land. What it does is settle what happens after one has: where an ordinary lucky strike might glance off into an ordinary wound, an oiled edge finds the gap almost every time. An hour to a coat, five coats to the flask, and it will take to anything that cuts or punctures. A bolt spends a whole use on itself.
It was found in Orvayne’s house, on the night the party broke in to cure him of the Wraithblade curse, among the ordinary oils a man keeps for maintaining his weapons, which is why nobody looked at it twice at first. One of them smelled wrong for the shelf it was on, and familiar: the smell of Gwenivere’s shop. It came out of that search alongside three volumes of the Mól Encyclopædia and a bundle of Beltran’s instruction-letters, in a bedroom whose walls were scrawled over with Martyr, please and must hurt me.
It was still in the party’s kit on the day they went after Beltran for the last time, and it went onto the blades that morning with everything else they had.
