Unified Theory Feat 15
Prerequisite(s) legendary in Arcana
You’ve started to make a meaningful connection about the common underpinnings of the four traditions of magic and magical essences, allowing you to understand them all through an arcane lens. Whenever you use an action or a skill feat that requires a Nature, Occultism, or Religion check, depending on the magic tradition, you can use Arcana instead. If you would normally take a penalty or have a higher DC for using Arcana on other magic (such as when using Identify Magic), you no longer do so.
