question regarding 34 orb run.

Sooo im on my first god run trying to do a 33 or 34 orb ending. Im pretty unkillable at the moment(100perks, unlimited healing and digging and such) at 29 orbs in new game +. So why would i need to do the great treasure chest thing for that 34th orb? cant i just dig myself into another parallel world to pick up the 34th there? if thats Not the possible for whatever reason then i wonder the following: Can i obtain the spell End of Everything within new game plus or should i have visited the robotic egg to get that spell before i went to new game +. Im not sure if i unlocked it ever before, or if that is even necessary

p.s. here is a video from earlier in the run. anyone that wonders what several instances of trick greed, blood money etc looks like. wouldnt recommend cuz of fps issues when something dies.
