Best Ultimate Bunny Modules (Hard)

More Modules can be seen by scrolling horizontally on mobile.

This build is exactly the same as our Base Bunny Build since Ultimate Bunny does not need to change her equipments and modules to achieve the best build.

For Ultimate Bunny's Hard mode build, we'll be focusing on modules that will allow you to continuously spam Ultimate Bunny's Lightning Emission skill for massive DPS. This is possible with Focus on Electric and Singular Specialist for increased Skill Power, and Nimble Fingers for reduced Skill Cooldowns.

You can also prolong the duration of her sprint skill, Speed of Light, by getting the MP Collector, since this module grants you the ability to recover MP upon killing an enemy. In addition, the Electric Transition, Increased HP, and Increased DEF modules should be enough to increase your survivability out on the battlefield.

Alternative Descendant Module for Bosses

Module Change Explanation
The First Descendant - MP CollectorMP Collector > The First Descendant - An Iron WillAn Iron Will Replace MP Collector with An Iron Will for more survivability.
The First Descendant - Nimble FingersNimble Fingers > The First Descendant - Lethal InfectionLethal Infection Replace Nimble Fingers with Lethal Infection for additional Skill Power Modifier.

For bossing, MP Collector may not be that handy as there won't be a lot of mobs in the colossus, save for a few KingFishers. With that said, it may be worth replacing it with An Iron Will, as you'll need all the durability you can get when taking on the most powerful bosses in Hard Mode.

It is also recommended to replace Nimble Fingers with Lethal Infection to get bonus Skill Power Modifiers upon landing Firearm Critical Hits. This is particularly useful since you'll mostly be relying on weapons to deal damage rather than skills in boss fights.

Descendant Module Substitutes for Mobbing

Module Change Explanation
The First Descendant - Nimble FingersNimble Fingers > The First Descendant - MP AccelerantMP Accelerant Replace Nimble Fingers with MP Accelerant for longer Skill Duration.

If you want to use Lightning Emission for a longer period of time, you can swap out Nimble Fingers with MP Accelerant to increase Skill Duration.

All in all, it still depends on whether you want to use Ultimate Bunny's skills for an extended period of time, or if you prefer reduced skill cooldowns. If it's the latter, then you can stick with Nimble Fingers.

Best Weapon Modules

More Modules can be seen by scrolling horizontally on mobile.

For weapon modules, you'll want to equip modules that will improve Critical Rate and Damage, as well as your Firearm ATK to boost the overall power of your weapon.

As Ultimate Bunny, the Electric Conductor is also a must-have module, since it adds bonus damage when firing on enemies affected by her electricity skills.

Note that External Components with set bonuses have fixed main stats.

The Tingling Mechanics Reactor is the best Reactor to use for Bunny in Hard Mode due to the Electric Skill Power Boost Ratio that it has to strengthen your Electric skills, particularly the Lightning Emission skill, which you will often use as Bunny.

Equipping the Supernova Set will further empower Bunny's Electric damage output as the set increases the Electric Skill Power Modifier. You will also be able to activate the Executioner's Thunderbolt to deal additional damage to your target upon hitting them with your Electricity skills.

Ultimate Bunny Playstyle Tips

Ultimate Bunny Playstyle Tips


Charge Electricity by Moving Around

Ultimate Bunny relies on her Electricity skills, but before you can cast any of them out, you'll have to build up Electricity by running around.

Try to make it a habit of moving around in circles even when you have to stay and defend one area so that you'll always have some Electricity charged up in case you have to use them.

Use Lightning Emission and Speed of Light at the Same Time

The time it takes to release each wave of the Lightning Emission skill depends on how fast you are moving around. With Speed of Light active, you'll be able to sprint faster and this will constantly unleash waves of electricity a lot quicker!

Use Reload Cancel

You can cut the reload time in half by reloading, then wait for the reload meter to reach halfway, and then use any of Bunny's skills (except Lightning Emission) to instantly reload your weapon. This isn't only limited to skills, but you can also perform actions such as rolling or using the grappling hook.

These modules are chosen to improve your Skill Damage, reduce Skill Cooldown, help you manage Skill Cost, and extend your skill's Range. Since Bunny's Lightning Emission covers a large area, it's highly recommended to focus on boosting your skill damage and reducing cooldown to make it more spammable and effective for area clearing.

Additionally, decreasing your Skill Cost will help you sustain the Speed of Light, as it rapidly depletes your MP pool.

Since the Thunder Cage is a submachine gun, you will face issues with high recoil and low ammo capacity. However, due to the nature of Ultimate Bunny's kit, you'll be engaging in short to mid-range fights to keep enemies within range of your skills, so recoil control won't be an issue. To address the low ammo capacity, you'll stack magazine capacity upgrades.

Furthermore, this build focuses on increasing your Critical Hit Rate, Critical Hit Damage, and Firearm ATK to maximize overall DPS against any enemy.

Since you will be frequently casting Lightning Emission, which is both an Electric and Singular skill, it is best to use a Tingling Singularity Reactor. This reactor is your best option, as it provides a Skill Power Boost for both of these skill types.

The Battle Aesthetics Set complements Ultimate Bunny's entire kit, as she relies on landing Critical Hits with Lightning Emission to eliminate nearby enemies while using Speed of Light. This set also reduces the MP cost of your skills, which is particularly helpful given the high cost of maintaining Speed of Light.

As for the stat priority, it is highly recommended to prioritize defensive stats to enhance your survivability if you get cornered.

Ultimate Bunny Exclusive Equipment

Ultimate Equipment, Ultra-lightweight Motile Battlesuit 'White Rabbit'

This Ultimate equipment wasn't originally intended for Bunny, but an unexpected 'field test' conducted by Bunny revealed its true potential. The micro-vibrations of the battlesuit boots gave even greater power and speed boosts thanks to the biocurrents generated by Bunny, allowing her to generate even more currents and manifest Arche abilities that are many times more powerful than before. The only downside is that the rare element unique to this Ultimate equipment turns her hair white.
