In Dungeons and Dragons, Arcana is a skill linked to Intelligence that measures a characters ability to recall lore about spells, magic items, eldritch symbols, magical traditions, planes of existence, and magical creatures. It can also be used to decipher complex magics, magical puzzles, or as a way to interact with magical devices that aren’t strictly magic items. Additionally, proficiency in Arcana is required to scribe scrolls. The skill check for Arcana can be used to gather knowledge on magical related topics. For example, a player can roll an Arcana check to recognize or know of a certain spell or creature of magical origin. However, it should not be used for things that spells like Detect Magic or Identify should be used for.
