About Harpoon
The Harpoon is a free-to-play tool in Old School RuneScape.
"Useful for catching really big fish"
Over the last 30 days it traded between 78 and 722 gp on the Grand Exchange, averaging 218 gp. About 1,582 units changed hands per day. The price is down 22.4% across that window. The Grand Exchange buy limit is 40 every 4 hours. Selling one at the average price costs 4 gp in Grand Exchange tax.
Casting High Level Alchemy returns 3 gp, which is 98.6% below the 30-day average price, so alching a bought one loses money.
