Reach Neural Sanctum
Follow this route with Alloyed Collective enabled:
Access Node → Conduit Canyon → Solutional Haunt → Computational Exchange → Decrypted Portal → Neural Sanctum.
Supply the required Sentry Terminals with Sentry Keys in Conduit Canyon and finish the Alloy Hunter teleporter event. Activate both Heat Vents in Solutional Haunt and defeat Solus Wing. Collect Encrypted Cerebellum and use the teleporter at the boss’s eyes to enter Computational Exchange.
Find Wandering CHEF beside the waterfall to the left of SPEX. Craft Exposed Cerebellum with an accepted component, offer it at the Charity Shrine, and enter the Decrypted Portal. Attack the orb in Neural Sanctum to start Solus Heart. Defeating Solus Wing alone does not reach this encounter.
Handle the fight
| Threat | Response |
|---|---|
| Red projectiles | Move sideways around them or destroy them |
| Blue homing shots | Destroy them promptly instead of focusing only on the boss |
| White bombs and beams | Keep an escape route; they can destroy the platforms beneath you |
| Purple electric zones | Move out when the warning appears |
Around each third of its health lost, the boss changes phase, grows, and becomes temporarily invulnerable. Avoid the central slam, then move through the gaps between paired columns of beams. Do not trade your safety for attacks during invulnerability.
Area damage helps clear destructible threats. Save movement and jumps to preserve a safe position when platforms are damaged.
Accept or reject the offering
When the boss first reaches 0 HP and falls to the bottom of the arena, Offering of the Collective creates the decision point:
- Accept: interact with the offering to end the run with Decompiled.
- Reject: keep attacking and finish killing the boss. Collect the legendary drop and use the subsequent exit to continue.
If you want to reject, do not interact with the offering. If you want the ending, stop attacking and accept it.
