We can't find any source for this item (quests reward, drop, etc). It's highly probable this item is not obtainable right now. It seems that the New Ever Giving is obtainable.
Does anyone know if this level 62 mob can drop this 600gs?
Jasmine the giver/Dau-shen the Unstoppable (Same location on map) did indeed drop the evergiven as an epic. https://i.imgur.com/B0Cru2q.png
Its epic in game, without Refreshing passive, also mob is called Dau-Shen
