- Purchased from the blacksmith, Andre of Astora, for 20,000 souls.
- Andre of Astora drops the Crest of Artorias if it wasn't bought from him already.
It is used to open the magical door in Darkroot Garden that leads to the Forest Hunter Covenant and the Great Grey Wolf Sif. Though an impression for the crest resides on both sides of the door, unlocking of the door can only be accomplished from the Darkroot Garden side and not the Forest Hunter Covenant side.
- The in-game description of the Crest of Artorias gives some hints about what lies behind the magical door in Darkroot Garden. The local bandits refer to the Forest Hunter Covenant members that attack the player when they go through the magical door. The uninitiated refers to people who are not part of the Forest Hunter covenant because if the player joins the covenant, the bandits will not attack anymore.
