Bunny Build Guide — Fastest Farmer in The First Descendant
Bunny is the fastest mob farmer in The First Descendant — here is her electric speed-clear build, reactor, and the weapons that keep her at max sprint.
If you’ve ever watched a 90-second dungeon clear and wondered how, the answer is usually Bunny. She’s the speed farmer of the game: build electricity by moving, then vaporize everything around you.
What Bunny actually does
Her whole kit rewards movement. Light Speeding (skill 2) boosts sprint speed and electricity gain, Thrill Bomb (skill 1) drops an Electro Orb, Lightning Emission (skill 3) damages everything you run past while electrified, and Maximum Power (skill 4) is a single-target nuke that scales with how long you’ve been active. The Rabbit Foot passive charges electricity on movement and double-jumps.
Best weapon pairing
Thunder Cage is the classic — its overcharge shockwave stacks perfectly with her electric field. For pure speed you often don’t even fire: a stat-stick weapon with sprint and grapple-hook cores (Peace Maker, Blue Beetle, Secret Garden, or Thunder Cage itself) gets you to the 1600 sprint cap when skill 2 is active. Afterglow Sword is your ranged weak-point option; Shadow is a fun sword pick.
Reactor + skill match
A Tingling Mixture reactor (Electric + Singular, or Electric + Fusion) is the answer. Match the optimization condition to your weapon — SMG for Thunder Cage. Substats: Electric Skill Power Boost, Singular Skill Power Boost, and Skill Cooldown.
Core modules
Electric Master, Electric Specialist, Nimble Fingers, Strong Mentality, Skill Extension, and MP Collector keep her spinning. Electrical Transition, Electric Condense, and Enlightenment smooth the resource game, with Increased HP or Increased Shield if you’re squishy. For gear, a 4-piece Pulsating Power set pushes you to ~14k HP and 37k DEF for damage and survive-ability.
