The First Descendant: 3 Ultimate Bunny Builds

IMPORTANT READ: WITH THE CHANGES TO REACTOR MOUNTING ON OCT 10TH, THE MOUNTING CAN BE CHANGED TO A WEAPON OF YOUR PREFERENCE, LIKE A LIGHTWEIGHT WEAPON SUCH AS SIDEARMS OR SMG

Best Bunny Reactor Sub-stats
Critical Damage + Singular > For Bossing/Invasions if using Crit Bunny build
Electric + Singular > For Mobbing if using Non-Crit damage build

If you wish to use Bunny for Colossus
For Crit Bunny – Critical Damage + Colossus Damage
For Non-Crit Bunny – Singular + Colossus damage
On the Math side of the game, Singular Boost on reactor will give a higher increase in burst and total damage than a Electric Boost would. But only a small % between, 5% to 8% increase
8k HP and 9k DEF is enough to survive Invasion Bosses

Have enough Range with a single mod for 17meters, for more than that some damage or survivability will have to be lost.

Similar to the full crit bunny, but instead, lost a little bit of HP to go for maximum range, since this is designed for mobbing and not invasions/bosses, 5k HP is enough to not worry about enemies.
And i still decided to go for all 4 crit mods, since i didnt want to utilize more crystals to change the slots, you could change one of the purple crit mods for Electric Syncthium for extra electric base damage.

For the Electric Transition build, the transcendent mod gives extra survivability by regenerating Shield, while also keeping a good damage and range (21meters)
