The Eternal Laboratory is an area where players can take part in end game content (in the form of the map system) by using the Map Device.
It can be accessed once you have completed the quests for Lady Dialla in Solaris Temple Level 2 in Act 3 on Merciless difficulty. You can then use a waypoint to get there.
After completing a quest for the master Zana, she will reside in the Eternal Laboratory. If you invite her to your hideout, you can place your own map device there.
- The Eternal Laboratory has been visually revamped and is now present in the Solaris Temple. In Normal and Cruel difficulties, it contains lore.
- The Eternal Laboratory is now available in Act Three rather than Act Two. You get access from Lady Dialla.
- The Eternal Laboratory was added to the game.
