Reactor and External Components

Tingling Singularity Reactor 

Since we use Thunder Cage, the Tingling Singularity Reactor with electric skill power, and singular skill power is the best choice. The best skill affixes are Skill Effect Range and Skill Duration UP. If you can't have both, it's best to get Skill Duration UP.

Annihilation Set (External Components) 
The set consists of Annihilation Auxiliary Power, Annihilation Sensor, Annihilation Memory, and Annihilation Processor.

2-Set: Enhances skill duration. 
4-Set: Increases firearm attack proportionally to the ratio of max HP to HP lost, up to a 26% increase. 
When HP is 50% or lower, the set provides a 16.4% HP recovery for 10 seconds, with a cooldown of 30 seconds, complementing the build's HP. Although it reduces MP recovery by 22%, it is negligible for this large build with unlimited MP.

You need to get the Annihilation Set from the Void Intercept Devourer(Hard).

Annihilation Set Attributes 
Annihilation Auxiliary Power 
DEF 3,512 
Max HP 898 
DBNO Duration 0.237x

Annihilation Sensor

Max Shield 253

The properties of the suit components are mainly Max HP and DEF, which will work together with Bunny Mods to provide more fuel for Bionic Fuel. The biggest advantage is that it provides a 16.4% HP recovery for 10 seconds, which can effectively replenish Bunny's HP. If you can't get this set, you can try to use modules such as Defense or Max HP instead. You can also choose to buy Annihilation Set, which is currently only $8.9, and you can get an additional 5% discount by using the discount code 'harry'.

Ultimate Bunny Build

The core of Ultimate Bunny Building is how to keep her Lightning Emission skill usable continuously, which requires her MP to be in the best state at all times.

Bionic Fuel consumes HP instead of MP. It is the core mod of infinite MP and allows Lightning Emission to continue. Therefore, we need to maintain health. Agony improves our defense, which has a great positive effect on maintaining HP. And HP Collector will instantly restore 9% of Max HP when we kill an enemy, which means that the higher the maximum HP, the more it will be restored. Therefore, we need to maximize Max HP.

Max HP Boost Mod 
Time Distribution 
Skill Cooldown -14.3%, Max HP +52.4%

Stim Accelerant 
Max HP+234%,Max MP-15%

lncreased HP 
Max HP +218.5%

Time Distribution, Stim Accelerant, and lncreased HP together provide about 505% of Max HP, allowing HP Collector to work efficiently while reducing skill cooldown time.

Improve Lightning Emission Mod 
Focus on Electric 
Electric Skill Power +77.2%, Skill Cooldown-6.1%

Focus on Singular 
Singular Skill Power Modifier +68.2%, SkillCooldown -6.1%

Skill Expansion 
Skill Effect Range +92.3%

Maximize Range 
Skill Effect Range +24%, Skill PowerModifier-5%

Lightning Emission is Bunny's Singular skill. Focus on Electric and Focus on Singular can effectively increase its damage and reduce skill cooldown, and are key modules to maintain Lightning Emission.

Skill Expansion and Maximize Range work together to increase Lightning Emission's effective range by 116%, allowing it to attack more targets. If your Max HP is already high, you can reduce the Capacity Cost of Stim Accelerant to 8, increase the Maximize Range, and add another module that can increase Max HP to the last free slot.

The final effect of these modules working together is not only reflected in HP and MP but also in the Lightning Emission skill, which has a cooldown of 22 seconds and a duration of 23.2 seconds, which means you can keep Lightning Emission working continuously.
