@ Everyone If you haven't got any residuum on you (I know Fina has ...) I will allow you to swap up to 10% of any gold you find for residuum. So if you find 100gp, you can break it down as 90gp and 10 residuum.
Everyone OK with that ??
Oh, and the residuum swap out is before you take a share, so if you find 1200 gp, you convert 120gp of that to residuum, then take your share (so you could take the whole 120 residuum and 80 gp ... if no one else wanted the residuum ...)
I still think to this day that the ID'ing of magic items was a huge gaping whole they made in the game :0
