I always make filling the monster chest a priority. Not because the loot has ever been impressive to me, but because the faster I can get them done the faster the cool down ends and may cause rare elemental chest to pop up.
Normal monster chests usually give me things like common herbs and x1 gem. Then this happened so unexpectedly.
I would expect a suprise goody like that from the mystic vision before I would expect it from here. Either this was an extremely lucky chest or I have been unlucky with regular chests the entire time I have been playing
If the regular monster chest has ever given you great loot feel free to share the info with me.
