The 100K ARC Damage challenge in The First Descendant looks tougher than it really is. The counter doesn't care how stylish the kill was or whether you dropped an elite in a single burst. It cares about total Arc damage, so repeated hits and crowded encounters matter far more than flashy numbers. That changes the way you should approach the event. Instead of chasing bosses across the map, build around constant combat, quick resets, and enemy packs that stay close together. You'll also pick up materials and gear along the way, much like a good farming run for ARC Raiders BluePrints, where every minute needs to produce something useful.

Build Around Bunny's Movement

Bunny is still the easiest Descendant to use for this challenge, mainly because her damage follows her movement. You don't need to stand still and line up every shot. Run through a group, keep your skills active, and let the electric damage do its job while you reposition. That rhythm feels much better than slowly picking off enemies one at a time.

When tuning the build, skill power should come first, but don't ignore range or cooldown reduction. A little more range lets Bunny tag enemies before they spread out, while shorter cooldowns keep the damage running between waves. Skill duration is useful too, especially in missions where enemies spawn in several small groups instead of one large mob. Energy recovery can make the setup feel smoother, although the exact balance depends on your modules and how aggressively you move. If you're constantly running dry, the build may look strong on paper but still waste time during actual farming.

Use Weapons That Keep the Counter Moving

Your weapon doesn't need to replace Bunny's abilities. It needs to cover the moments when enemies survive the first pass or spawn just outside your skill range. Fast-firing weapons work well because they create more damage events and let you finish scattered targets without breaking your route. Electric effects are a natural fit, but reliable area damage is usually more valuable than chasing one perfect elemental bonus.

Try to avoid weapons that force you into a slow, stop-and-start playstyle. A hard-hitting rifle can delete one target, yet it may be a poor choice when ten weaker enemies are standing in the next room. Shotguns, rapid-fire rifles, and weapons with explosive or chaining effects tend to feel better here. Reload speed matters more than many players expect. Every long reload is a quiet interruption, and those interruptions add up across a full session. Carry something that lets you fire, move, and get back to your skills without fuss.

Pick Farming Routes, Not Just Missions

The best location isn't always the mission with the highest enemy level. For this event, dense spawns and short travel distances are usually more important. Look for areas where weak enemies arrive in groups, respawn quickly, and can be pulled into Bunny's range without much effort. Once you find a route that works, repeat it instead of jumping between random activities. Familiarity helps. You'll learn where the next wave appears, when to turn, and which corners let you catch several targets with one pass.

Keep moving whenever the mission allows it. Waiting beside an empty spawn point is one of the easiest ways to slow the challenge down. Clear the current pack, head towards the next trigger, and use your weapon on anything that survives. There's no need to chase a single straggler halfway across the map. If an enemy wanders too far away, leave it and keep the route flowing. The objective is not to create the biggest individual hit. It's to produce a steady stream of Arc damage over the whole run.

Make Each Run Count

Before starting a longer farming session, check your reactor, modules, and weapon enhancements. You don't need a perfect endgame setup, but small upgrades can make a noticeable difference when they reduce the number of attacks needed per group. Activate useful experience or resource bonuses if you have them. The challenge itself may be your main reason for playing, but the same run can also provide proficiency, crafting materials, and equipment for later builds.

It's also worth managing your inventory as you go. Keep items that support Bunny or another Descendant you actually plan to play, and don't let a full inventory interrupt a good farming loop. Bosses can wait unless they're part of another objective you're already completing. Spending several minutes on a durable target often gives less progress than clearing several waves of weaker enemies. After a few runs, you'll usually know whether the route is paying off by how rarely you stop to reload, recover energy, or search for the next group.

Final Thoughts

The quickest way through the 100K ARC Damage challenge is to treat it as a momentum test. Bunny supplies the movement and sustained electric damage, while a fast weapon handles stragglers and awkward spawn points. Choose a compact farming route, keep the enemies coming, and resist the urge to turn every encounter into a boss fight. You'll reach the target sooner if you focus on damage instances rather than dramatic kills, and the extra materials can help you prepare for future content or buy ARC Raiders Gear when you're ready to improve another loadout.
