The Aion site has been updated with a great preview of all of the new content coming with the Ereshkigal's Wrath update on March 27th. Players will find a number of new instances for endgame players as well as a revamped Glory Points system, some class and skill updates, and some new Transformations.
Class & Skill Updates
There’s a slew of changes coming for each class! Along with changes to class balancing, each class is also getting three new Legendary Daevanion skills. If you have extra Skillbooks laying around, you’ll be able to use them in new ways! Use the new Daevanion Skill Enchantment system to charge up Skillbook abilities you’ve already learned or use Daevanion Skillbook Synthesis to turn your unused Skillbooks into a new one at random.
