Overview

Two states

  • Normalregular patterns
  • Insanered only · she takes +30%

About 30s each with no hits.

Gauge and lives (solo values)

Red hit (Easy/Normal/Hard)
↓ −200/400/600
Purple hit (Easy/Normal/Hard)
↓ −80/80/160
Any red hit · lives
↓ −1 Death Count
Clean Insane window · lives
↑ +1 Death Count
  • Red attacks cost a life Red hits take 1 Death Count and cut the gauge hard; purple hits cut it a little.
  • Shared gauge 0–1000, party-wide, moving about 31 per second: roughly 30s per state.
  • Insane mode Red attacks only; each one hurts her, and she takes +30% damage.
  • Clean Insane, +1 life Survive a whole window un-hit to regain a life (that player only). Any hit heals her.
  • Sigils start Berserk Three sigils trigger a three-weapon attack chain.
  • Binds skip a state Outside her rampage, a bind flips to the next state.
  • Hidden markers Normal and Hard hide most ranges; Hard is faster.

Danger

  • Double-axe Berserk Hands fill the map (Phase 1 under 50%, all of Phase 2). Bind it or use invincibility.
  • Phase 2 below 50% Pinball adds a final slam (up-jump); the border sequence adds a bottom-centre charge.
  • Hits snowball One hit invites panicked follow-ups; failed runs lose lives in a row.

Tips

  • Vanish? Crouch first Upright somersault: crouch. Inverted: jump. In Insane, wait for the full red form.
  • Horizontal, vertical, X Crouch, dash through on time (never early), stand still. Call Phase 2's triple tell aloud.
  • Bottom-centre charge Up-jump. Axe raised: dash behind her. Axe to the side: stay crouched.
  • Pinball Default to the left side.
  • Read sigils in binds They show the next Berserk sequence.

Strategies

Dodge first

Low risk · High damage requirement

First clears or below the minimum cut

  1. Stop attacking during every tell; add damage only once dodges are consistent.
  2. Treat each Insane window as a no-hit check; a clean one refunds a life.
  3. After a hit, reset and focus on the next tell instead of chasing damage.

Payoff Clean Insane windows come about once a minute and refund lives; slower clear

Share spare lives

Medium risk · Medium damage requirement

Duo or trio where one member has spare Death Count

  1. The gauge is shared but the Insane refund is personal; the member with spare lives may take a pattern on purpose so others can finish Insane clean.
  2. Hits during Insane heal Bellona, so only do this when a teammate is short on lives.

Payoff Teammates may refund lives more often (unconfirmed interpretation of the source)

Notes

  • MapleSEA Overdrive Announced for v255 in Easy, Normal and Hard. HP and mechanics use KMS data.
  • Entry and credit Post-OVERDRIVE only. Level 280 and [Solatum] The Truth of Solatum; break the Ark after the kill.
  • Spec unconfirmed From a Namu Wiki summary and a pre-release estimate.

Recommended · Easy KMS solo minimum about 45-51k (Aug 2026, unconfirmed).
