Kamień drogi are obelisks which act as magical portals allowing travel between two different places. They are activated by a combination of three witcher signs. W grze Wiedźmin, wayfarer's stones are used to enter and exit three starożytnych kryptach located in the swamp cemetery and each pair is activated with a unique combination of Igni and Aard.
There is also a pair wayfarer's stones which feature in one of the quests in the module. These stones allow passage from the magazyn in the slums to an elven ruin and back. These are activated by casting the Znak Aard three times in a row.
