Characters with this skill can detect the presence of a magical artifact by touch in the same way as Magical Sense. However, this ability is not a magical one; it is simply a matter of experience and knowledge.
Should characters encounter a magical artifact of unknown type, they may use this skill to try to find out something about it. The gamesmaster should make a test against the character's Int. Success indicates that the character remembers reading or hearing something potentially useful about the object and the gamesmaster can provide information accordingly.
