A core component of every build inThe First Descendantis your character’s reactor. This is a small piece of equipment that determines the base damage of your skills as well as your melee attack damage, otherwise known as sub damage. Getting a strong reactor is critical to min-maxing your damage in Hard mode.
Farming for a good reactor is surprisingly easy if you know where to look. Today, we’ll be showcasing how to farm reactors quickly and efficiently in Hard difficulty. We go over how target farming works, all the reactor affixes you can chase, and give some tips on how to quickly earn a strong reactor for your build.

Finding The Perfect Reactor
Before you start farming for reactors,you need to beat the main campaign.This will unlock Hard difficulty, which gives you access to target-farming strategies that are impossible to replicate in Normal mode. You’ll also be able to earn Level 100 reactors in Hard mode. If you haven’t gotten that far in the game yet, don’t even worry about reactors. Use whichever reactor gives you the highest ability damage and ignore the rest.
After you beat the campaign, set the game’s difficulty to Hard. you may do this from the map menu. Once set,press “F” on M&K or “Start” on controller to bring up a reward menu.This menu showcases every unique drop table in Hard mode, notably every unique combination of reactor you can farm for this week.

Drop sources for reactors and external components rotate every Tuesday at 12:30 UTC. This does not apply to mission rewards or enemy drop tables.
Reactor Tags
Each zone in the game will have a set reactor that drops throughout the week. These reactors are broken up into three subtypes:
Elementdetermines the reactor’s base damage type. If a zone says it drops toxic reactors, then every reactor is going to benefit toxic Descendants. This hasnobearing on affixes, however. Potential elements include electric, toxic, chill, fire, and non-attribute.

Ammo typerefers to the reactor’s weapon usage bonus. For Ultimate Reactors, this will be a specific Ultimate weapon you’re holding. The ammo type determines which Ultimate weapons can roll on the reactor. General only rolls General ammo weapons (such as Divine Punishment and Last Dagger), Special only rolls Special ammo weapons, etc.
Skill typeis one of the 20% buffs you get for using a skill that matches the listed skill type. Every Descendant skill is tagged as dimensional, singular, fusion, or tech. This bonus only applies to skills with a matching tag. If you get a singular skill and your character has a mix of singular and tech skills, then only the singular skills will see any benefit.

You can filter for each tag at the top of the reward menu. Select any of the drop-down menus near the top of the UI and select the exact element, ammo type, and skill type you’re targeting. For example, if you were farming for a good Bunny reactor, you’d want an electric reactor tuned for singular skills. For an easier farm, you might opt for Impact ammo since it has a small pool of weapons to roll from.
As you can see, we can find that exact reactor type in Fallen Ark this week. Selecting the drop source will bring you straight to that location on the map.Every enemy in the zone has a high chance of dropping that exact reactor type; the modifiers you selected are set on those monsters. Affixes and the chosen weapon are still random, but everything else is static. This makes farming for a perfect reactor quite easy, if a little tedious.
Reactor Affixes
Rare and Ultimate reactors always drop with two randomized affixes, both of which are listed on the bottom of the item’s description. In the above example, our reactor rolled with more Skill Range and Toxic Skill Power.Affixes are entirely random andcannotbe rerolled,unlike weapons. If you’re looking for a certain affix combination, you’ll need to farm for duplicates of the same reactor.
