The Eternal Laboratory

For information on the map device, see Map Device.

The Eternal Laboratory is a subarea of The Solaris Temple Level 2 in Act 3. It contains two pieces of environmental lore: the Reverie Device and Malachai's Journal.

It used to be a separate area instance, but it is removed in version 3.0.0.

Despite the layout of The Solaris Temple Level 2 in Act 3 and Act 8 is largely the same, this subarea is absent from Act 8 version. The door to the subarea is closed and not interactable.

It contains a crafting bench recipe to unlock.
