There is a bug with modification of Eder Defender abilbity on levelup. If levelup is used and Wary Defender is chosen, when Defender mode is active, the tooltip doesn't change. It still shows info about unmodified ability. Moreover, the ability can't be deactivated after such modification. The only solution, I could find, was deactivating Defender before its modification on levelup. Everything works and shows just fine, if done that way.
