How to beat Ophion (final boss)

The final boss. ~10 minutes of bullet hell across multiple phases. The fight rewards patient DPS and punishes greed.

General tips

Adrenaline level 5 is the goal. Don't take a single hit if you can help it. Level 5 grants free reloads which doubles your DPS.
Two Astronaut Figurines + at least 3 Silphium Resin before entering. Anything less, restart.
Use Reconstructor in safe rooms before the boss door.

Phase 1: orbital lasers

Long, slow beams sweep the arena. Dash sideways through them with i-frames, don't try to outrun.
Ophion fires homing red orbs — strafe perpendicular.

Phase 2: tentacles + teleport

Ophion teleports to one of three positions. Watch the screen for the marker — it tells you where she'll appear.
Tentacles slam down marked zones. Stay out.

Phase 3: bullet hell

The hardest phase. Dense patterns, multiple layers. Stand in the arena center, not the edges — the patterns thin in the middle.
Use your Alt-fire offensively here, not defensively.

Loadout that works

Hollowseeker with Portal Beam + Critical Hit — best in slot for the final boss.
Pyroshell Caster as backup — Phase 1 melt.

If stuck: if you die in Phase 3, your DPS is fine — your survival failed. Stop trying to dodge by running away. Center of the arena, dash through patterns, accept that you'll take 1-2 hits.

Then the credits roll. But it's not really over — there's a true ending.
