The Sacred clay harpoon is obtained from transforming a proto-tool bought from Rewards Mystic with 20 Stealing Creation points. 24,450 bonus experience could be gained from it, which will be stored and used up while training Fishing. A difference from normal harpoons is that this one can be held in player's weapon 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.
