How to Get Reactors

Buy from Deslin

Reactors can be bought from Deslin, the Weapon Lab Director. However, the reactors he has available are only level 1.

Complete Missions

Reactors can be obtained by completing missions, which is arguably the best way to get them since you can get high-tier and high-level ones. You can see what reactors can be obtained when you complete a mission in the Reward Info before you initiate the mission.

Missions List

Target Farm Reactors in Hard Mode

You can target farm specific reactors in Hard Mode. Simply go to your map and choose Difficulty Level Rewards (press F), then select a region that offers a high drop chance of a specific reactor you're after.

Hard Mode Guide

How to Equip Reactors

Go to the Inventory Screen

To equip reactors, open first the Inventory screen. From there, select the Reactor slot at the upper-right to go to the reactor screen.

Select a Reactor to Equip

In the Reactor screen, just select and drag a Reactor to the Reactor Slot to equip it.

How to Dismantle Reactors

Mark Reactors as Junk

In the Reactors screen, mark all the reactors for dismantling as junk. Reactors that have a trash can icon on them are marked as junk.

Press the Dismantle Button

Once reactors are marked, just press the button for Dismantle Junk.

Obtain Materials After Dismantling

Dismantling reactors gives you Superconductor Cores and Solenoids. They are research materials that can be used to craft weapons or make descendants, so they're valuable resources.

Reactors Explanation

Name Indicates the Bonuses

Although reactors might seem to have random names at first, they follow some naming format. You can have a good idea of the reactor's Skill Power Bonus Ratio stat just by looking at its name.

Knowing this naming format allows you to quickly determine whether you want to keep the reactor or discard it.

Reactor Name Table

Name	Element Skill Power Bonus Ratio
Burning	Fire
Frozen	Chill
Toxic	Toxic
Materialized	Non-Attribute
Tingling	Electric
Name	Skill Type Skill Power Bonus Ratio
Phase	Dimension
Mixture	Fusion
Mechanics	Tech
Singularity	Singular

Skill Power Boost Ratio Checkmarks Depends on the Character

In this image, we can see that there are no checkmarks in the reactor's Skill Power Boost Ratio because Lepic is not a Toxic-element character, and he does not have any Fusion-type skill.

In this image, we can see that there is only one checkmark in the reactor's Skill Power Boost Ratio because Lepic is not an Electric-element character, but he does have a Singular-type skill.

In this image, we can see that both have checkmarks in the reactor's Skill Power Boost Ratio because Lepic is a Fire-element character, and he does have a Tech-type skill.

The checkmarks under the Skill Power Boost Ratio Depend on the character you're using. If your character has Fire as its element, then any reactor that has a Fire Skill Power Boost Ratio will always have a check on it.

Moreover, your character's skill types also follow the same rule. So if your character has Tech and Singular skill types, then any reactor that has Tech Skill Power Boost Ratio or Singular Skill Power Boost Ratio will always have a check on it.

Skill Power When Equipped is Fixed to the Character

Just like the checkmarks, the skills displayed under the Skill Power When Equipped are fixed to the character you're using. So if you're using Lepic, you'll always see the character's skills displayed there.

They Only Really Differ in Tier and Level

In the images above, although the Reactors are different, all their Skill Power and Sub Attack Power stats are the same since they are all level 7 and are all Rare reactors.

Reactors only differ in their tier and level. The higher the Reactor's level the better its Skill Power and Sub Attack Power stats are. The higher the Reactor's tier (Standard, Rare, or Ultimate) the more bonuses it gives in general.

Ultimate and Rare Tier Reactors have Optimization Conditions

Ultimate	Rare

Ultimate-tier and Rare-tier reactors have Optimization Condition as part of the bonuses they give. These conditions refer to weapons that you need to obtain or wield. By fulfilling this condition, you can further boost the reactor's bonus. In the image for Ultimate reactors above, the reactor only gives a 100% boost to Skill Power, but if the condition is fulfilled, it jumps to 160%.
