The Chaos Temple hut in Level 38 Wilderness.

The exterior of the temple.

The Chaos Temple is a structure in level 38 Wilderness, west of the Lava Maze. It contains a chaos altar where players can recharge and train their Prayer.

A wine of zamorak spawns on a table inside the hut, which can only be obtained by casting Telekinetic Grab. Players who have completed the hard Wilderness Diary will receive them in noted form.

Players who kill the Chaos Fanatic may use the chaos altar to recharge their Prayer as it is very close.

The chaos altar

Members can also offer bones on the chaos altar, which grants the same Prayer experience bonus as a gilded altar with two burners lit. Outside, the Elder Chaos druid can unnote a player's bones for 50 coins per bone.

In addition, there is also a 50% chance that the bone offered will not be consumed. The saved bone can continue to roll for the 50% chance to be saved again until the roll fails.

Thus, the expected extra bones per bone purchased can be calculated with the following infinite series,

which evaluates to 1.

On average, players "gain" 1 extra bone for every bone they use on the altar. This results in a 100% gain in experience (i.e. if a player uses 1000 dragon bones, they will average 504 experience per bone).
