This article is about the perk. For other uses, see Mysterious (disambiguation).

Mysterious is an Invention perk. It can be created in weapon, armour, and tool gizmos.

The perk was made to live up to its name of being mysterious. Jagex have not confirmed any theories of what that effect is or how the perk activates, though they have confirmed the effect is neutral[1], and isn't useful for high-level players.[2]

When the perk activates, it gives a message in the chat box: You feel something mysterious take effect.

A secondary effect of the perk is that it drastically increases the drop rate of the Mysterious egg (item) from monsters inside the Dragonkin Laboratory.[3]

This combination is more likely to give Mysterious 6 on a tool gizmo compared to weapon or armour gizmos, however it is paired with Confused 3 perk which should be avoided.

History[edit | edit source]

The Mysterious perk has been a hot discussion topic since its release, with players spending much time looking for its hidden purpose; some promising finders rewards up to a billion gold coins. When the perk was developed in 2016, the intention was to change its effect whenever the players were close to figuring out what it did. After Mod Moltare's departure, this design was not maintained. The perk's main effect has remained the same, as developed by Mod Rowley.

Various hints have been released over time to discourage players from finding the perk. Jagex claims its effect is boring and not worth looking for.[5] In 2017, Mod Moltare made the following comment: "Those testing it: you may find it helpful to keep some screenshots with timestamps, for later reference."[6] The validity of the comment was later questioned by Mod Moltare.[7]
