Reaching 100,000 Arc damage in The First Descendant sounds like a bigger job than it really is. The challenge isn't asking you to defeat 100,000 enemies, and it doesn't require one huge hit either. It simply counts the Arc damage you deal during your runs. That changes the way you should approach it. A fast, repeatable route with plenty of targets will beat a slow mission packed with tough enemies almost every time. You can also use the run to collect gear and materials, much like players who search for ARC Raiders BluePrints while trying to get more value from every expedition. Once you focus on damage uptime rather than flashy numbers, the challenge becomes far less intimidating.

Why Bunny Fits the Challenge

Bunny is the obvious choice for this task, mainly because she can keep dealing damage while moving. You won't need to stop, line up every shot, and wait for enemies to gather. Her electric abilities work around her movement, which makes crowded areas much easier to clear. Keep sprinting through groups and you'll notice the damage counter rising in the background. That steady stream matters more than landing a powerful attack once every few seconds. Build Bunny around Skill Power first, then look for Skill Range, cooldown reduction, and Skill Duration. Energy recovery is useful too, especially during longer farming sessions. If your build runs dry after one group, it isn't helping much. A slightly weaker setup that keeps abilities active can produce more Arc damage over time than a high-power build with long gaps between casts.

Choose Damage Frequency Over Big Numbers

Your weapon still matters, but this isn't the place to obsess over the biggest damage figure on the screen. Rapid-fire weapons and guns with splash effects are usually more helpful because they create more chances to trigger elemental damage. Look for something that can hit several enemies, reload without a long pause, and keep working when the fight gets messy. Electric effects are a natural fit for Bunny, although reliable area damage can also do the job. Try not to spend the whole run chasing isolated targets. If one enemy wanders away from the group, leave it and move towards the next pack. You're trying to create a constant rhythm: enter an area, trigger your skills, fire into the crowd, and move on before the route loses momentum. That rhythm is where the progress comes from.

Build a Route Around Enemy Density

The best farming spot is rarely the mission with the strongest rewards listed on the map. For this challenge, weak enemies are often more useful than elites because they appear in groups and return quickly. Look for compact areas where you can move from one wave to the next without long travel sections. Missions with open spaces and slow spawn cycles tend to waste time, even when the enemies give better loot. Run the route a few times and pay attention to where the next group appears. You'll soon find a pattern. Stay in motion, but don't rush so far ahead that you leave enemies alive behind you. Bunny's speed can make that easy to do. A clean loop is better than random movement, especially when you're farming solo and every spawn depends on your position.

Make Each Run Pay for Itself

There's no reason to treat the challenge as a separate grind from the rest of your progression. Turn on any useful bonuses before starting, and use the opportunity to level weapons or gather materials for later upgrades. Check your reactor and modules when you return to Albion. A small increase in Skill Power, range, or duration can make the next run noticeably smoother. Don't dismantle every item without checking it first, either. Some drops may suit another Descendant or help complete a weapon setup you haven't finished. Bosses can be worth fighting when they're part of the mission route, but going out of your way for a slow single-target battle usually hurts your damage per minute. The challenge rewards consistency, so keep the route simple and avoid decisions that interrupt your flow.

Final Thoughts

The 100K Arc Damage Challenge is mainly a test of efficiency, not raw character strength. Bunny gives you the mobility and steady electric pressure needed to keep the counter moving, while a fast weapon helps fill the gaps between skill activations. Farm dense enemy groups, pick routes with short travel times, and keep moving instead of waiting for perfect spawns. You'll also collect useful gear along the way, and careful players can turn extra drops into materials or future upgrades rather than letting them disappear into the inventory. Once you settle into a repeatable loop, the target comes much quicker than expected, leaving more time to work towards other goals, including ARC Raiders buy Loot when you're ready for another loot-focused grind.
