Just to signal a bug where you can infinitely farm a boss (and his drop), I explain myself:
Right before accessing “The end of Time” for the first time, you fight that boss anomaly (which I don’t recall the name sorry) and after you kill it you talk to the “plant” speaking of the Epoch.
But if you create a teleport instead of taking the “???” rift, first it brings you to the new zone “end of time”, but it also reset that boss when you take the TP back.
I know it’s not very clear and I apologise for that
I hope it’s clear enough tough.
Thank you !
