Foul scents are produced whenever a criminal action occurs, and can be used to try to track down the perpetrator, the perpetrator's hearth fire, and to recover stolen property. Scents last a certain amount of game days before disappearing.

To see scents go to Adventure > Toggles -> Toggle Tracking.

Most scents allow you to summon the criminal at their hearth fire by left clicking the scent, right clicking the hearth fire, and selecting "Force summon"(Needs Rage skill). This allows you to summon their character even while they are off-line. Note that this can be done at a distance - as long as you can see the hearth fire, force summon will be possible. NOTE: If the criminal has no hearthfire, they can be summoned anywhere in the world by rightclicking the scent on the ground.

Leaving a scent gives you two debuffs:

1.Redhanded - lasts for a short period of time, you cannot log off or use travel function while it lasts.

2.Outlaw - lasts for the period of scent (look below for the table).Your character can't log off while it lasts and also you can't use charterstones travel function.

A scent can be taken an unlimited number of times before it expires. However, a container (including your inventory) can only hold 1 scent for a particular crime at a time. Scents do expire in your inventory or containers.

Scents can also be used to craft a Nidbane Fetter which if used in conjunction with Runed Dolmen, will sumon a Nidbane and allow you to take revenge on a player.

Note: You cannot use scents of assault of trespassing when crafting a Nidbane Fetter

See the Stealth page for more info on leaving/tracking scents.
