Is it possible to add a direct essence for growth mechanic to other character like Kanathar has?
If we limit it to characters that have ascended. Tiadane, Ethrex, and Ferro fit the bill.
Or partners which would then include Abel, Leviathan, and Torgar.
Side note: I love the current Leviathan but do also miss the aimless version that grew if you cared to invest the time.
