<onlyinclude>The Arcana skill represents dedicated study into the workings of arcane magic. While that study manifests itself most strongly as the ability to better understand and recognize arcane magics, those who study Arcana also learn the underpinnings of creatures created and maintained with those magics, constructs and the undead. Characters with substantial training in Arcana can even use arcane spell completion trigger items containing spells not normally accessible within their class and ignore attribute requirements on magical items.
