Cerberus

The third descent boss, an infernal possessed form of the three-headed Hound of Hades, fought in the fast and deadly Fields of Mourning.

Cerberus is the third boss of the descent and the gate at the bottom of the Fields of Mourning, the fast, dangerous region below Oceanus. This is not the friendly Hound from the Crossroads. Chronos has corrupted him, and you face an infernal, possessed variant of the three-headed beast. Defeating him does not kill him. It frees him from what is controlling him.

The fight

Cerberus is a melee brute with three heads and the speed of the region he guards. Where the earlier descent bosses test your reading and your attention, Cerberus tests your reflexes. He closes distance fast, and the Fields of Mourning has already trained the run to deal with quick, aggressive enemies, so this fight is the payoff of that lesson at boss scale. The research does not detail a fixed multi-phase script, so treat him as a high-pressure aggression check rather than a puzzle to solve in a set order.

Do not try to out-trade Cerberus by standing your ground. He is built to overwhelm a stationary target, so the players who lose here are usually the ones who plant their feet and swing instead of moving.

How to approach it

Mobility wins this one. Hold Sprint to keep moving and create space, then turn and punish in the gaps rather than committing to long stationary combos. A weapon with fast, reliable hits suits him better than a slow heavy swing you can get interrupted out of, though a strong Omega burst still works if you only fire it when you have made room. This is a good fight for a high-damage core that ends rooms quickly, for example Zeus Blitz or Hestia Scorch, so you shorten the window in which his speed can catch you. Keep your Magick for burst openings, not panic casts.

What makes it hard

Cerberus is hard because he is fast and you are deep in the run. By the third descent region your health pool has usually taken hits from earlier rooms, and his aggression does not give you the recovery time the earlier bosses did. There is little room to think. You either have the reflexes and the positioning down, or his speed closes the gap before your damage does.

What beating it means

Beating Cerberus frees the Hound and opens the way to Tartarus, the fortress of Chronos and the final descent region. He is the last test before the run’s true endboss, the point where the descent stops easing you in and starts demanding that your build actually performs under pressure. Clearing him reliably means you are ready to take on Chronos.
