The 100K ARC Damage Challenge in The First Descendant can look like a serious grind at first, but it becomes much more manageable once you stop treating it like a normal kill-count mission. The game is tracking damage dealt, not just the number of enemies you defeat. That changes the best approach completely. You want crowded areas, repeated waves, and abilities that keep hitting while you move. It is also a good chance to collect materials and gear for other projects, much like a run focused on ARC Raiders BluePrints, where every trip is better when it serves more than one purpose.

Build Around Constant Damage

Bunny is still the easiest Descendant to recommend for this challenge. Her speed lets you move from one group to the next without wasting much time, and her electric skills can damage several enemies during a single pass. You do not need to stand still and aim at every target. Keep running through the area, circle back when the groups gather, and let the skills do their work.

For the build itself, skill power is useful, but it should not be the only thing you chase. Skill range helps Bunny reach more enemies, while cooldown reduction keeps her abilities available between waves. Duration is handy too, especially when you are clearing a packed room and do not want the damage to stop halfway through. Energy recovery can make the rotation feel much smoother. You will notice the difference quickly. A build that looks slightly weaker on paper may perform better if it lets you stay active without constant pauses.

Choose Weapons That Keep the Screen Busy

Your weapon does not need to compete with Bunny for the top damage number. It needs to support the pace of the run. Fast-firing guns, electric effects, and weapons with splash or chain damage are usually better than slow rifles built around single-target hits. The challenge rewards frequent damage events, so a weapon that tags several enemies in a short burst can be more useful than one that delivers a huge critical hit to a single target.

Reload speed matters more than many players expect. Losing a few seconds after every wave adds up over a long farming session. Look for a comfortable magazine size, steady recoil, and enough range to hit enemies while you are moving. You can use your gun to finish stragglers, soften tougher targets, or keep the damage counter moving while Bunny's skills are recovering. There is no need to force one perfect weapon if another option feels more reliable in actual combat.

Farm Dense Enemy Waves

The best location is not always the one with the strongest enemies or the most impressive rewards. For this objective, density and spawn speed are more important. Areas with compact layouts and weak enemies tend to produce better results because you spend less time travelling between fights. Clear one group, move towards the next spawn point, and keep the route flowing. Waiting in an empty room is one of the easiest ways to slow the challenge down.

Try to avoid getting distracted by isolated elites unless they are already part of your route. They may have more health, but that does not necessarily mean they provide better progress for your time. A large pack gives you many targets for one skill rotation. That is the real advantage. If the area starts to feel quiet, reset the mission or change zones rather than standing around hoping the next wave appears soon. A clean, repeatable route will usually beat a more difficult area that leaves you with long gaps between encounters.

Make Each Run Count

There is no need to rush blindly. A few small habits can make the whole process less tiring. Activate useful experience or resource bonuses before you begin, then keep an eye on your reactor, modules, and weapon upgrades. Even a modest improvement to skill damage or cooldowns can remove several rotations from the run. If your inventory fills up, take a moment to check for useful components instead of dismantling everything automatically. You may find an upgrade for another Descendant or a weapon you have not finished building.

It also helps to play around Bunny's movement rather than fighting against it. Do not stop in the middle of a group unless you have to. Run wide circles, pull enemies together, and pass through the pack again when your electric damage is active. If your energy runs low, use your weapon for a few seconds while you reposition. This keeps the combat rhythm intact and prevents the challenge from turning into a series of slow starts and stops.

Final Thoughts

The fastest way to complete the 100K ARC Damage Challenge is to create more damage opportunities, not simply to chase bigger numbers. Bunny's mobility makes her a natural fit, while skill range, cooldown reduction, duration, and steady energy recovery keep her damage running. Pair that setup with a quick weapon and a dense farming route, and the target should arrive far sooner than expected. You will also leave with materials and gear that can support later builds, including runs where cheap ARC Raiders Items help stretch your wider game budget, so the farming time does not feel wasted.
