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 main effect of the perk is currently unknown. Mod Moltare hinted that the function of the perk can be discovered by analysing timestamps[1] and that the perk does not do anything that would make it mandatory for high-level players.[2] After he left Jagex, he posted one more hint on Twitter stating that the perk triggers under the same circumstances as other perks, and when it does, it rolls a number between 0 and 19, which is then compared to the perk's rank.[3]

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.[4]

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.
