The Sacred clay hammer 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 Smithing or Construction.
- The sacred clay hammer had the normal hammer animation for Smithing until the Stealing Creation update in December 2008. The animation for Construction was updated in February 2009.
- When used with Varrock armour 3 to speed up the smithing process, it used to show the normal hammer in the animation instead of the sacred clay hammer, but this has since been updated.
- If the sacred clay hammer and a regular hammer are both in the player's inventory, while smithing a number of items, it will switch back and forth between the two hammers.
- When there are multiple sacred clay hammers in your inventory, the first one in your inventory is used.
