Strange rock

The Strange rock is an item from the Shattered Heart Distraction and Diversion. It may be found randomly while training any non-combat skill. Players may get two strange rocks per skill. The first rock is rare. The second rock is faster to obtain. Each strange rock is a segment of the statue of Dahmaroc, a wizard from the Second Age. After the statue of Dahmaroc has been completed, players may then again get two strange rocks per non-combat skill to once again complete the statue. The first time you complete the statue, you are given a statue plinth place in your player-owned house.

If you try to add the strange rock to the plinth for the very first time, Barnabus Hurma will stop you. Speak to him and you will show him the strange rock you have found; he will then say that you need to find its twin before you can add it to the plinth.

Strange rocks will not appear under a player's gravestone when he or she dies and are not stackable in the bank.

The Construction strange rock is obtained simply by standing in your player-owned house for over a minute. This is the only Strange Rock that can be acquired without actually training the skill. When you are doing any skill and you receive the rock while your inventory is full, its message would be: "Something odd happens to the [X] and you are left with a strange rock." While [X] would be the item that was last made or obtained.

Rewards
After using a pair of strange rocks on the Statue plinth, the player gets $$y = x^2 - 2x + 100$$ where $$y$$ = Experience earned and $$x$$ = Skill level of the skill being trained when the rock is added to the statue. The player needs two rocks from each skill to complete the statue. When the player has collected two pieces in one skill, they can be added to the plinth in order to create a section of the Dahmaroc statue. The plinth is located in the Varrock Museum right next to the entrance. Once you complete the statue you get a replica plinth to put in your POH and you get a replica piece of statue to start the statue in your POH and you get to begin the search for pieces again which gives you a shot at the extra exp again.

You can use a Statue list to keep track which rocks you've added to the statue. You have to have two pieces to be able to add to the plinth.

Icons and Descriptions
You can identify what skill a strange rock is by examining it. Also, the different skills' rocks have different appearances. When trying to collect a strange rock by doing any of these, you will hear a small "thud" sound to say you now have a strange rock. ''Note: These are only the examine texts for the rocks themselves, not the only ways to obtain them. For methods of getting them, please check the Shattered Heart article.''
