The criteria for this trophy is the same as the 4 sub trophies. Collect 20,000 gold, collect 150 Orbs, do not die at all and complete the game in under 2hrs 30mins.
There's no other way to do this apart from practice, keep replaying the game and getting your completion times down and figure out your best paths for avoiding death, don't forget that if you die you can just dashboard and close the app and it will still count. The hardest part of this is getting the 20,000 gold within the time limit, I'd advise leaving all of the minerals on the first level as they're not worth very much, and just concentrate on clearing all of the 3rd level along with part of 2nd to get the required amount. Keep exiting back to the main menu when you save so you can check your time when you reload. I'd also advise backing your save up to a usb or the cloud before you go and face the final boss incase you are short on any orbs, that way you can just reload and go and get the required orbs before finishing again, as long as you're clearing all of the caves and finding all of the secret areas then you should get the orbs pretty comfortably. Good luck!
