Hargate's Mysteries

This is a small Act 6 side quest, available on encountering a Strange Crystal Formation in The Infestation, if the player has completed The Origin of the Slith and kept Hargate's Formula.

The strange crystal hums with unusual energies, and resembles a phenomenon described in Hargate's Formula. Perhaps comparing the notes with the formation will help make sense of some of the late Hargate's work.

Objectives

 * Study the Crystal Formation using Hargate's Formula

Guide
The Strange Crystal Formation can be found in the final section of The Infestation. Choosing to study the crystal will destroy it and complete the quest. The reward on Ultimate will allow the player to summon a floating Aether Crystal pet.
