Minor Exploit, Level ones can get Celestial Treasure Boxes

Pretty much what the title says,
you can get a level one to timeless isle and kill the world boss on a higher level character. Then the level one gets black prince rep and the box that contains gold, motes, and gear. Right now it takes me 6-7 mins to get from the major panda city to timeless so not sure if it's a good gold farm. If anyone has any insight on this let me know. You could use warlock summon but you'd need extra accounts or help from a friend
