NIKKE Burst System Explained: Burst Gauge, the 3 Stages & Full Burst
Burst Gauge, the I→II→III order and Full Burst — NIKKE's signature mechanic
The Burst Gauge is a shared squad-wide energy bar capped at 10,000. The single most misunderstood point: the gauge does NOT scale with the damage you deal — it scales with your hit count. That means weapon type matters more for gauge speed than raw ATK.
Energy per hit by weapon type (source: the NIKKE community):
- Rocket Launcher: 345–355 energy per shot — fastest fill
- Sniper Rifle: 265–290 energy per shot
- Shotgun: 45 energy × 10 pellets per shot (each pellet counted separately, so total per shot is high)
- Assault Rifle: 20–45 energy per shot
- Submachine Gun (SMG): 10–15 energy per shot
- Machine Gun: only 5 energy per shot — the slowest, offset by a very high fire rate
A few bonus rules worth remembering: multi-hit skills add energy per individual hit; hitting multiple enemies at once (AoE) grants bonus energy; hitting a boss or large target gives DOUBLE the energy of a normal enemy; and for charge weapons, the energy you gain does NOT depend on how much you charged — even a partial charge counts in full.
Once the Burst Gauge is full, the fight enters the Burst Phase, split into 3 mandatory sequential steps — no reordering, no skipping:
- Burst Skill I — only characters with Burst Type I (usually Supporters) can act here. There's no time limit; you can hold this stage as long as you like before activating it.
- Burst Skill II — only Burst Type II characters (usually your main DPS). You get exactly 10 seconds from entering Stage II to use the skill; miss the window and the whole Full Burst sequence RESETS, forcing you to refill the gauge from scratch.
- Burst Skill III — only Burst Type III characters. Also a 10-second window, same reset penalty if missed.
On cooldowns: Burst III's cooldown is fairly consistent across sources at roughly ~40 seconds. Burst I and II cooldowns are usually cited around ~20 seconds, but that figure is a composite from sources that don't fully agree — treat it as a reference estimate rather than a hard number for every character.
Immediately after Burst Skill III lands successfully, Full Burst triggers automatically — a 10-second window where the whole squad gets a damage boost. This is the core tactical goal of every NIKKE rotation.
Timing Full Burst against a boss or large target pays off twice over: the gauge refills faster (bosses grant double energy) and many targets expose separate parts that take extra piercing damage.
Because the I → II → III order is mandatory, a squad missing even one Burst type gets permanently stuck at that stage — it will never reach Full Burst no matter how strong the squad otherwise is. As the NIKKE community puts it: "a squad missing Burst II stalls indefinitely, rendering Full Burst inaccessible."
That's why a standard squad always needs all three pieces: 1 Burst I + 1 Burst II + 1 Burst III (plus 2 flexible slots) — a formula the community calls "1-1-2-Flex" or "1-1-3". Strong players optimize further with cooldown-reduction (CDR) supports to shorten the gap between Full Bursts, ideally repeating one roughly every 20 seconds.
