This article is about the reward item purchased with Stealing Creation points for use outside of the minigame. For the Harpoons used inside the minigame, see Harpoon (Stealing Creation).
The sacred clay harpoon is obtained from transforming a proto-tool bought from Rewards Mystic with 20 Stealing Creation points. 24,450 bonus experience is gained from it, which is stored and used up while training Fishing. A difference from normal harpoons is that this one can be held in player's main hand slot like a barb-tail harpoon. This item can be stored in the Tackle box. Unlike other fishing equipment, only one sacred clay harpoon may be stored at a time.
The harpoon moves through the "dipping" motion twice as fast as a normal harpoon, but the player waits twice as long between harpoon throws.
On the day of release, there was a glitch that prevented fishing while equipped.
There is a glitch which prevents players from fishing swordfish and tuna; you could only fish sharks. This glitch is resolved by logging out and then back in again.
