As per Three's suggestions in the Skill Review survey, I've taken a look at how Aura/Shadow Form, Aura Shield and Shadow Cloak are written out in comparison to similar skills Elemental Manipulation and Elemental Shield and decided to combine the Anyeli elemental skills with the Nymph/Zanaryan elements. (As the game's developed, Light/Shadow have become extra elements anyway, so this made the most sense.) Now, instead of upgrading Aura Form, you'll need to upgrade Elemental Manipulation.

This grants you more freedom with the light/shadow abilities and opens the skills up to a broader interpretation, but they're still restricted to Light for Apali and Shadow for Skotadi.

I've already updated the skills of those Apali/Skotadi with the previous form, so you don't even have to do anything. Just remember next time you want to upgrade that you're looking for the Elemental skills instead.
