Blizzard has hotfixed in a new Earthen racial called Quiet Contemplation, that allows them to restore health and mana without food items.
Earthen previously had issues with restoring health and mana between pulls or in arenas thanks to their unique racial, Ingest Minerals, which gives them a permanent Well Fed buff at the cost of being unable to eat food.
While Blizzard recently addressed this by fixing their stat issues and adding in a vendor with cheap gems to eat as a replacement, they now have a built-in racial that accomplishes this task — Quiet Contemplation!
In addition to its effect as a replacement for food and mana restoration, Quiet Contemplation also comes with a small unique animation, showing the player Earthen nibbling on a gem and reading a nice book.
