Introduction

Completing void reactors is an important part of the game loop in The First Descendant. All void reactors require the use of void shards to summon the boss. You can view where to obtain all the void shards in The First Descendant by checking our All Void Fragment Locations Guide. Each void reactor has associated amorphous materials that can be opened once you defeat the void reactor boss. The below tables list all void reactors and their amorphous materials, so you can easily see where to go to open your amorphous.

The tables also list the shards required to activate the void reactor, and what type of boss you will encounter. An elite is a “yellow bar” enemy or enemies. A boss designates a boss that will have multiple phases. This will be either orbs that spawn, or the additional adds that spawn.
