Is released to open the rings, why not release its use at level 50-59
if you want to wait for the event to boost the eudemon lvl you can, but if you want to use eudaemon crystals to boost the morphs you can actually do that anytime you want. if you double click a completed morph it also takes you to the eudaemon page and you can use the crystals there, but my advice is don't actually activate the new morph until you get another one that way you can keep accessing the page.
Since they released the enchanted rings, why do not they soon enable them to level 50-59?
Very good this update
