Prometheus

Prometheus is the third boss of the ascent and the gate near the top of Mount Olympus, the region where Melinoë climbs toward the gods. He stands between you and the Summit, the final surface area, which makes him the last boss before the run’s surface endboss. The research is thin on his specific patterns, so this guide describes how to approach him rather than inventing an attack list the source does not support.

The fight

Prometheus guards the upper reach of Mount Olympus, the source of the Adamant reagent, and he is the penultimate test on the surface ladder. The research does not lay out his phases or a fixed move set in detail, so treat him as a late-surface boss: a fight you reach with a built-out run, expecting boss-tier pressure rather than the gentler patterns of the early surface. Read his attacks live, react to telegraphs, and do not assume a script the game has not shown you.

Because the public detail on Prometheus is limited, scout him on your first attempts rather than committing to a memorized routine. Treat the early goes as reconnaissance, learn what he actually does, then bring a plan back.

How to approach it

Bring a build that has already proven itself against Eris and Polyphemus, because by Mount Olympus you should be running a committed damage engine backed by your Arcana Cards and a deep boon stack. Sprint to stay mobile and dodge his telegraphs, spend Magick and Omega on the openings, and keep a Selene Hex charged for the moments the fight gets crowded or you need to spike his health down. A flexible, reliable core matters more than a hard counter here, since you are reading him live rather than exploiting a known weakness.

What makes it hard

The difficulty is depth plus the unknown. He sits near the top of the surface path, so you fight him with a run that has already spent resources and taken hits, and the limited public detail means you cannot lean on a memorized solution the way you can with bosses you have studied. You have to actually play the fight in front of you, which is harder than executing a rehearsed pattern.

What beating it means

Beating Prometheus opens the Summit and the path to Typhon, the final surface boss. He is the last step before the climax of the ascent, the equivalent of Cerberus on the descent: the gate that confirms your build is ready for the path’s endboss. Clearing him reliably means the only thing left on the surface is Typhon himself.
