The 100K ARC Damage Challenge in The First Descendant sounds like a huge grind when you first read the requirement. In practice, it is more about choosing the right enemies and keeping your damage rolling than chasing one massive hit. You do not need to spend the whole evening fighting bosses. A fast route through crowded areas will usually get you there sooner, while also giving you materials and gear to use later. That same "get more from every run" mindset works well when collecting ARC Raiders BluePrints, where a good route can matter just as much as the equipment you bring.
Why Bunny Makes the Challenge Easier
Bunny is still one of the most comfortable choices for this objective. Her kit rewards movement, and that fits the challenge perfectly. You can run through a pack, trigger your electric skills, and keep moving before the next group has even settled into position. There is very little wasted time. You are not standing still, lining up every shot, or waiting for a long cooldown before doing anything useful.
When tuning Bunny, focus on Skill Power first, then look for Skill Range, Skill Duration, and Cooldown Reduction. Range is especially useful in crowded missions because it lets your electric damage touch more targets without forcing you to run directly into the middle of every group. Duration helps keep the effect active while you travel between spawns. Energy recovery also deserves attention. Running out of energy halfway through a route can ruin your rhythm, and the challenge is much quicker when your abilities stay active for most of the session.
You will notice the difference almost immediately. Instead of treating each enemy as a separate target, you start thinking about the whole group. Sprint through the area, let the damage tick, and turn only when you need to gather the next wave. Bunny is at her best when you keep the pace high.
Weapons That Keep Damage Ticking
Your weapon does not have to carry the entire build, but it should support the way you are farming. Fast-firing guns are generally more useful here than slow weapons with impressive damage per shot. A weapon that hits several enemies, applies an elemental effect, or produces small area explosions can add a steady stream of damage while Bunny handles the main clearing.
Reload speed matters more than many players expect. A long reload creates a dead moment, and those small pauses add up over a full run. Look for a comfortable magazine size, reliable accuracy at close and medium range, and effects that activate often rather than occasionally. Electric bonuses are a natural fit, though consistent area damage from another element can still perform well if the weapon has better mods and stronger overall stats.
Do not feel pressured to copy a setup designed for boss damage. A bossing weapon can be excellent in the right mission but awkward for this challenge. You want something that lets you shoot, reload, and move without breaking your flow. If a weapon kills one tough enemy quickly but struggles against a dozen weaker targets, it probably is not the best choice for building the meter.
Picking a Farming Route
The best farming location is rarely the one with the strongest enemies. Look for compact areas with frequent waves, short travel distances, and enemies that fall quickly to skills. Dense groups create more damage events, which is exactly what the challenge tracks. A route with several small packs can outperform a slower mission filled with elite targets, even if the elites award better individual drops.
Keep moving instead of waiting in one spot for the next spawn. Clear a group, push forward, and return through the route once the enemies have started coming back. If the area has a nearby mission loop or repeatable activity, use it. The aim is to spend as little time as possible running through empty corridors.
It is also worth paying attention to enemy placement. Some groups stand close enough for one electric burst to reach nearly all of them. Others are spread across awkward terrain and force you to waste time repositioning. After a couple of runs, you will know which sections are worth clearing and which ones can be ignored. That small bit of route knowledge often saves more time than another minor module upgrade.
Small Changes That Save Time
Before starting a longer session, check your modules, reactor, and weapon enhancements. You do not need a perfect endgame build, but weak or mismatched upgrades can make the challenge feel much slower than it should. Add experience or resource boosts when you have them. The extra rewards are useful, and there is little reason to farm without taking advantage of available bonuses.
Try not to get distracted by isolated bosses unless they are part of the route or another task you are already completing. A single boss may take longer than several waves of regular enemies, and the damage gained per minute can be disappointing. The same applies to inventory management. Pick up useful materials, but do not stop every few minutes to dismantle ordinary drops. Finish the run first, then sort everything in one go.
There is no need to restart after every imperfect run, either. Even a messy clear still adds progress. Keep an eye on your energy, avoid unnecessary deaths, and use cover when the area becomes crowded. The challenge rewards steady play more than flashy moments.
Final Thoughts
Bunny gives the 100K ARC Damage Challenge a straightforward rhythm: move quickly, keep your electric abilities active, and lead enemy groups into the same damage zone. Pair her with a rapid-fire weapon that handles crowds, then choose a compact farming route with frequent spawns. You will soon find that the number looks far less intimidating once the damage is coming from several targets at once. The extra materials and gear from each run can also support future progression, especially if you are building toward ARC Raiders BluePrints for sale and want every farming session to provide more than a single reward.
