A tetracompass (unpowered) is an artefact that can be restored with level 50 Archaeology. It can be turned into a tetracompass (powered) by powering it near the mysterious monolith at the Archaeology Campus, granting 970 Archaeology experience, up to ten at a time.

Tetracompass pieces are always dropped in order: left, right, dial, needle.

Ironmen players cannot restore tetracompasses until level 76 Archaeology (although it can be boosted), as this is the requirement to excavate malachite green and Armadylean yellow, both of which are the highest level materials required for its restoration.

Tetracompass value

The average loot value of an ancient casket from a tetracompass, only factoring archaeology materials, is 2,662,550 coins. This assumes an average of 5 material rolls (4-6 is the range for each ancient casket), and that each material has the same drop rate. As with all drop rates, results may vary.

The profit of a tetracompass (as shown in the table below) can be calculated because pieces are given from certain Archaeology collections. The following formula is used:

$T=(C-A)\times n-M$

Where:

• $T$ is the profit from acquiring and restoring one tetracompass (a negative value means the value of the chronotes received in the process is lower than the cost of the materials spent to acquire and restore the tetracompass)
• $C$ is the value of the chronotes given on completion of the collection each time (both for the individual artefacts and the collection as a whole)
• $A$ is the material cost of restoring all of the artefacts to complete collection
• $n$ is the number of times the collection needs to be completed to receive the pieces for a full tetracompass
• $M$ is the cost of the materials to restore the tetracompass (as shown in the table above)
