then i doubt any of us would know the only way i can think of is to fletch and alch yew longs you make a profit if you make either the bow strings nats or cut the yews yourself.
its prolly one of them odd ball items that no one thinks about but i do know that you can alch adamant plate bodys and loose very little the only problem is you can only buy 100 every 4 hours
I know how u need to be in the ship of somthing, and there drops this tar which can be sold for 200gp each. Spawns every 30 sec. So it's free/profit.
You should use search button
I've heard the only items that can give profit while alching are Adamant Plates, which are low loss if they don't profit, and a certain kind of pouch, idk what one.
