Apart from resetting Descendants to maximize power in the endgame, you’re able to also improve those module capacities using Energy Activators inThe First Descendant. These are some of the hardest enhancement materials to farm in the game, but we’ll give you the best strategy to farm each material to craft the Energy Activator. Here’s how to get Energy Activators in the First Descendant.
Where to Get Energy Activators in The First Descendant
There are two main ways to get Energy Activators. You can research them through Anais or buy them from the in-game shop withthe premium currency Calibers. To buy Energy Activators, go to the shop tab and look for the Support Material category. Scroll down and see Energy Activators going for 1,200 Calibers each.
Most players won’t buy the Energy Activators with real money (rightfully so), and even those who are willing to spend money shouldn’t because these are easily farmable materials when you know where to get them. To research or craft Energy Activators, you need the following materials:

These are some of the hardest materials to farm, which may be why they are 1,200 Calibers each. But instead, we’ll show you the best ways to farm each material.
Low-Carbon Activators – (Hard mode) Zone Recon Mission Fallen Theater: Vulgus Strategic Outpost in Kingston

Conductive Metallic Foils – (normal or hard mode) The Timberfall battlefield in Vespers
Heat Plasma Batteries – (normal or hard mode) The Haven Duty of the Descendant in Hagios
Polyatomic Ion Particles – (normal or hard mode) Aurora Forest Snowy Heights Supply Mission in Fortress
Out of all the strategies, the Conductive Metallic Foils are quite possibly the hardest. I also suggest farming those for last since you’ll need to farm some Codes to open those Encrypted Vaults. However, if you go through all the strategies, you should get enough codes, especially from the Snowy Heights supply missions.
Note: Research time takes 1 day and 16 hours, so it is best to farm this immediately to start the research.
How to Use Energy Activators in The First Descendant
To use Energy Activators, go to your Descendant Module menu and look for “Module Additional Settings.” Tap it and select “Max Capacity Up.” you’re able to only do this once per Descendant, and it’ll give you an additional 20-module capacity, which is one of the biggest power spikes in the endgame.
These Energy Activators are alsoneeded for Ultimate Weapons. They act the same way as Descendant modules, but you’ll need one Energy Activator for each weapon.
When using Energy Activators, make sure you are committed to using the Descendant and/or the Ultimate Weapon. This enhancement material is extremely hard to farm, so you need to be thrifty using them.
If youreset your Descendant’s level through Crystallization Catalysts, the Energy Activator bonus will still remain. So, you only need one for each Descendant you are planning to use.
You get two for free after finishing the campaign and one of the subquests. I made a mistake using it on my starter Descendant (not my planned main character), so I had to farm more.
