how do I enter zigguart map ???

yeah the changes to the end are just great , I'm too stupid to figure out how to enter zigguart map

its in the bottom left corner of the atlas. after you kill eater/exarch

yes but how do I enter it ? my eldrich voidstone is equipped , when I clicked on the map slot nothing happens , do I have to put something in Absence of patience and wisdom and Absence of symmetry and harmony slots ?

Use a nightmare map

"Progress" for areas outside of the normal Atlas, such as the Pinnacle Bosses, wasn't automatically unlocked for players. Even if you already have the Voidstone, that didn't confer completion status for the Eldritch bosses, which is required to access Nightmare maps--same mechanic as unlocking maps on the normal Atlas, have to complete an adjacent connected area first.

The areas for Pinnacle Bosses are complete when the socket they're in looks charged/blue. In this screenshot, Exarch has been completed, while Eater has not:

ok thank you very much , finally it makes sense
