The Witchers' medallion is a silver symbol of the witchers' profession. It is sensitive to magic, vibrating and tugging on its chain when spells are being cast or magical beings, like genies, are present. This magic medallion shaped like a wolf's head is given to every young witcher candidate who has passed the Trial of the Grasses. The origin of the first medallions is unknown, though it is assumed they were made in the magic forge at Kaer Morhen. The medallions vibrate in response to magic in all its forms, including curses, charms and spells. They also warn of lurking monsters born of magic or magic experimentation.
Notes
- According to Γκέραλτ in the short story Ο Κόκκος της Αλήθειας, no monster can touch a witcher's medallion.
- Leo Bonhart boasts a collection of three witcher medallions: a cat, a griffon and a wolf. After Bonhart's death in Pani Jeziora, Ciri claims the cat medallion for herself and gives the wolf one to Γκέραλτ (whose own original medallion was destroyed near the end of Ο Πύργος του Χελιδονιού).
- In Η Φωνή του Λόγου, part 4, Γκέραλτ refers to his as "the Sign of the Wolf's School".
- A wolf's-head keychain was part of the packaging for some editions of the original game.
Στο παιχνίδι The Witcher
In The Witcher, Γκέραλτ's medallion can be tuned to detect either monsters or Μαγεία. This particular screen can be found while Γκέραλτ is meditating, by clicking on the Inventory icon.
If the medallion is tuned to detect Τέρατα, it will vibrate whenever a monster is near. When the monster is very close, there will also be a red haze around the left side of the screen, and the medallion will vibrate quite violently.
If the medallion is tuned to detect magic, then it will vibrate in the same manner when in proximity to a Πεδίο της Δύναμης.
Finally, the ring around the medallion in the game interface (upper left corner) shows the icons for active effects and a progress bar for XP.

- Ζωτικότητα – indicates Γκέραλτ's health level. Reduction to zero results in death.
- Vigor – necessary to cast signs and/or block enemy blows.
- Toxicity – increases for the duration of each potion consumed, effectively limiting how many may be active at once.
