Here's a guide on the best Bunny Build in The First Descendant.

Game Guide by Ragib Rawnak on Aug 10, 2025

Bunny has gotten some big buffs that make her a powerhouse that can handle both groups of enemies and single targets.

These changes make her Electrical Condense ability and Thrill Bomb stronger, which makes her perfect for quickly clearing enemies while keeping her mobility edge.

This guide will help you optimize her new skills by selecting the right Mods, Gear, and strategies for easy gameplay.

Electrical Condense Changes

Two significant changes were made to Bunny's kit in the most recent updates. Thrill Bomb now does a lot more damage in The First Descendant.

It does 683 base damage plus an extra 15% skill power for every 10% of electricity held on to. If you keep all of your electricity, the damage you do could go up to 150%.

Electrical Condense, her fourth ability, changes from a beam attack to a charged explosion because of the bigger change.

This ability now needs to be charged for 5 seconds before it can do its full damage of 4,715 base damage plus an extra 1,550% for every 10% electricity kept.

With a base cooldown of 38 seconds, lowering the cooldown correctly lets you use this deadly ability almost all the time.

Sprint Speed Mechanics

While active, Electrical Condense gives Bunny a 20% boost to her sprint speed, which completely changes how she moves in The First Descendant.

Your base sprint speed is 1,096 when you're not moving, but when you use Electrical Condense, it goes up to 1,256.

When you do this and kill enemies that give you Inversion enhancements, you can run as fast as 1,300 without using her second ability.

Because of this change, she no longer has to keep up her second ability for moving speed all the time.

Her second ability still lets you build up electricity faster, but you don't need it to move at the fastest speed.

You can turn it on when electricity production is needed and off when it's not, which will significantly reduce MP usage.

Build Strategy and Mod Selection

Electric Condense is labelled as Fusion, but your build should focus on Singular Amplification. This method comes from the way modifier estimates work in the game.

Fusion mods add to Electrical Condense's already huge 4,715 base modifier, but the percentage gains aren't huge. For instance, adding a 68% boost only raises the total damage by about 1%.

On the other hand, Singular mods make her third ability, which has a base modifier of only 148, much better.

Adding the same 68% modifier makes this power almost twice as strong. The mods you choose should be Focus Electric, Electric Amplification, Focus on Singular, and Singular Amplification.

For this setting, don't use builds that focus on crit. Electrical Condense does 10–12 million damage and would benefit from crit ratios, but to get reasonable crit rates, you have to give up essential mods like Electrical Amplification and Singular Amplification in The First Descendant.

Because the ability doesn't happen very often, consistent damage is more useful than big hits every once in a while.

Your other mod spots should have Amplification Control to increase range without lowering power, Skill Expansion to cover more range, Double Cooldown with MP Conversion, and Nimble Fingers to increase the frequency of Electrical Condensate spam.

Maximize Conservation is your mod for managing your resources. This choice is better than MP Collector and Potent Collector because it lowers the cost of both MP and electricity for all skills.

Lower power costs make it easier to keep things, which directly increases Electrical Condense's damage output. This is especially helpful when you're meeting with your boss, and managing your resources is key to success.

Weapon Configuration

Since you won't be depending on weapon damage, you should choose weapons with sprint speed cores over damage capabilities.

You should have at least two sprint speed cores, but three will give you the most speed uptime. But keeping one Grappling Hook recharge time core gives you a lot of movement benefit, since grappling lets you move faster when you use a hook in The First Descendant.

This build works well with either Secret Garden or Peacemaker, though Peacemaker has slightly higher sprint speed numbers.

Adding Brisk Walk as a weapon mod will help you reach the moving speed cap more consistently, but you won't be able to go faster than the top speed.

Inversion Reinforcements

Adrenaline Rush is your main Inversion boost. It gives you 16% moving speed for 10 seconds, but then it cools down for 20 seconds.

This improvement helps you maintain your fastest speeds throughout your game sessions.

As alternative reinforcements, you should choose the Prosthetic Recovery System to improve MP recovery and Biodensity Augmentation to boost HP pools.

Quantum Domain gives you damage and range bonuses when you use skills, which lets you hit range caps while still being able to move around.

Arche Tuning Priorities

To get to the range cap quickly, choose Arche Tuning options that lower skill costs, boost skill power, and improve range in The First Descendant.

Enhanced Skill Power increases the damage you do, and more skill delay reduction lets you use Electrical Condensate more often.

Stay away from enhancements that focus on length because your cooldowns already overlap enough without them.

Also, don't use crit and crit damage boosts because they don't work with this build's damage plan. For better sustainability, priorities MP recovery modifiers and HP boosts.

Reactor and Component Setup

Your reactor should be an Electrical Fusion type, and the primary stat should be skill delay.

You can pick either Electrical Skill Power Boost Ratio or Fusion Power Boosts for your spare stats.

It does more damage to Electrical Condense when you use Fusion, but Electrical affects all of your skills in The First Descendant.

The most balanced way to improve general performance is to use electrical skills with skill cooldowns.

For your components, equip a two-piece Ascending Set and a two-piece Hunter Set. This mixture lowers both the cooldown and the cost of skills by 4%.

Both of these effects stack with other sources. The Slayer Set can do more damage, but it gives up the Quality of Life and ability to stay alive that the Ascending and Hunter sets do.

You can easily kill bosses with the current setup, so the extra damage from Slayer isn't needed when compared to the suggested combination's defensive and resource management benefits in The First Descendant.
