Arcana is a knowledge skill, based on Intelligence, which represents an academic knowledge of magic and how it works. It does not allow a character to sense magic that is otherwise not obvious, but it can be used to understand visible magical effects and the use of magical items, and to recognise magic when it is being worked.
Despite this, Michael Hing as Freezo frequently declares "I make an Arcana check" in all manner of situations where it probably isn't warranted. God/Dave is pretty lenient with this, sometimes giving the kind of information usually only discoverable by casting the spell detect magic, but in later episodes, after giving up trying to explain what an Arcana check is really for, just tells Hing whether something is magical or not.
