Buy nuema chests from 2nd tab in gods giving and keep opening and using the items from it until you are unable to use any of them. Other things like that that are easy to miss is meridian which is maxed instantly from account panel and titles from novice title stone (2nd tab in gods giving) if your char was made before it got given by the book that levels you to 150
This ^^, use Nuema chests and get the soulprime and life prime nuema orbs.Once you open the war avatar window.You see the tier level. Max tier is 8. If its not 8, you have to use the lifeprime and soul prime nuemas to increase it.
