Overview

Annihilation gauge · Extreme

Phase 1 passive
↓ +2%/s
Phase 2 passive
↓ +2.7%/s
Large arm hits Lotus
↑ ≈ −16 to −22%
Full in Phases 1-2
↓ 34 s Annihilation
Empty in Phase 3
↑ 25 s Safe Mode

Phase 3 has no passive rise.

Bombardment safe spots

  • Top-leftPhases 2-3 · the default
  • RightPhase 1
  • Bottom-rightPhases 2-3 · knockback risk

In Phase 3, portals link the two safe corners: use them to switch sides when the bombardment comes.

  • Annihilation gauge One per player; rises on its own in Phases 1-2 and from hits. Full means Annihilation Mode's extra patterns.
  • Lasers and arms Hitting you raises your gauge; hitting Lotus lowers it. Extreme adds a large arm after every 10th small one.
  • Per player The gauge freezes while you are dead; in a duo, Annihilation patterns are per player.

Danger

  • Horizontal bombardment Lethal beam; see Bombardment safe spots. The firing cannon itself is safe.
  • Large arm ~1 s warning on Extreme; 70% HP in Phase 1, 80% in Phases 2-3.
  • Darkness Aura Phase 3: stand on Lotus to dodge it, unless orange Gravity Restraint lasers bind you; then it deals 100%.
  • Drill Push and Current Discharge Drill Push into a corner hits twice. Current Discharge: 100% and a 2 s stun unless you leave the floor.
  • Bottom-right knockback Extreme Phase 3 bottom-right can knock you into the beam.

Tips

  • Clear the shield Extreme: a full arm set plus the large arm clears it; drag them through Lotus.
  • Drill Push Duck its rear spawn; never take it in a corner.
  • Ring swap Oz-ring swappers can swap under the shield; damage is cut 90% anyway.

Phases

Phase 1 white shield
  • White shield Every ~40 s: −90% damage for 20 s. Leftover shield heals Lotus, up to 20% max HP.
  • Strip it Aim lasers and arms through Lotus; binding stops only the shield pattern.
  • Clear the shield Extreme: one full arm set plus the large arm clears it; stand where you can drag them through Lotus.
  • Bombardment Safe on the right in Phase 1; the firing cannon itself is safe.
  • Large arm About 1 s warning on Extreme; hits 70% HP in Phase 1.
Phase 3 reversed gauge
  • Reversed gauge Annihilation Mode is the default. Only map attacks on Lotus lower the gauge; empty it for Safe Mode.
  • Drain sources Aim all three tracking lasers, the marked arms (above all the large arm) and missiles through Lotus.
  • Safe Mode burst Burst in the 25 s Safe Mode, then drain again as soon as Annihilation resumes.
  • Darkness Aura Stand on Lotus to dodge it, unless orange Gravity Restraint lasers bind you; then it deals 100%.
  • Bombardment corners Top-left is the default; portals link the safe corners. On Extreme, bottom-right can knock you into the beam.

Strategies

Standard duo

Medium risk · High damage requirement

Two players, the group's usual setup

  1. Phase 1 - stay central and let arms and lasers strip the shield rather than bursting into 90% damage reduction.
  2. Phases 1-2 - burst to phase before your gauge fills.
  3. Phase 2 - play top-left or bottom-right, which double as the bombardment safe zones.
  4. Phase 3 - default to top-left rather than bottom-right.

Payoff Short Phases 1-2 and fewer Annihilation Mode cycles

P3 gauge drain

Low risk · Low damage requirement

Always in Phase 3

  1. Aim all three tracking lasers, the marked arms (especially the large arm) and the missiles through Lotus.
  2. Burst during Safe Mode, then return to draining as soon as Annihilation Mode resumes.

Payoff 25 s Safe Mode windows, the only breaks in Phase 3

Notes

  • MapleSEA v244 changes No Phase 3 ceiling cannon, less bombing and shorter drone fields since Aug 2025; older guides overstate them.
  • Only Extreme tracked Normal and Hard: level 210, 300% PDR, up to 6 players.
  • HP estimates Overdrive HP is estimated from the published KMS reductions.
