Exiled Survivors Demon Lords Guide: All Nine, Ranked by What Kills You

The end of Exiled Survivors is a gauntlet of nine demon lords, each named in the game’s own achievement list: Satan the King of Hell, Acheron the All Seeing, Mephistopheles the Death Bringer, Balrug the Fiery, Belphegor the Ever-Watching, Lucifer the Duke of Metal, Beelzebub the Glutton, Mammon the Undying, and Phlegethon the Otherworldly.

The lords split by theme — fire, frost, lightning, poison, metal, undead, void, beholder and the king — and each theme demands a different answer. This guide covers what each theme does to you and what to bring.

The general rules for every lord

Three things are true of all nine fights:

They are damage races with a clock. Runs in this game are timed, and the lord fights are the longest encounters in it. A build that cannot sustain damage for the full fight loses even if it hits hard.

Telegraphs are everything. Every lord attack is telegraphed — growing zones, charging lines, spawning circles. The deaths that feel unfair are almost always players who panic-dodged into the second attack instead of walking out of the first.

Status effects decide the elemental fights. Frost lords slow you, fire lords burn you, poison lords stack miasma on you. Against elemental lords, the matching elemental Focus tier and a status-cleansing or status-immunizing plan matter more than raw damage.

The lords, by theme

Satan, The King of Hell — the final encounter and the closest thing to a mechanics exam. Expect a combination of the other lords’ attack patterns: zones, projectiles and slams in rotation. There is no trick; bring your most complete build and play clean. If you can beat Satan, the game is done.

Acheron, The All Seeing — the beholder fight. Gaze attacks and projectile barrages, with the extra cruelty of attacks that track you while you are out of position. The answer is constant movement in wide circles and never stopping to finish a cast. Standing still is the only way to lose this fight.

Mephistopheles, The Death Bringer — the void lord. Teleports and space-warping attacks that punish the kiting habits you learned earlier in the game, because the safe distance you memorize stops being safe. Fight it reactively: wait for the teleport, then commit to damage.

Balrug, The Fiery — the fire lord. Sustained burn zones that force constant repositioning. Burn damage over time is the killer here: a build that ignores its own health bar dies to the floor, not the boss. Bring damage that works while moving.

Belphegor, The Ever-Watching — the lightning lord, and the most mechanically demanding of the nine. Fast arcs and chained strikes mean your movement has to be unpredictable — wide circles, direction changes, no rhythm. This is the fight that separates good players from players who memorized one dodge.

Lucifer, The Duke of Metal — the metal lord. Heavy armor phases where armor break and single-target damage decide the fight. This is where the armor-dissolving skills earn their place: Caustic Shuriken’s acid burst and Basilisk’s Gaze both shatter armor, and against Lucifer that is worth more than any horde skill you own. Bring your single-target line.

Beelzebub, The Glutton — the poison lord. Swarms and plague zones; an attrition fight, not a burst fight. The damage race is long and the floor is lethal, so healing and sustain matter. Do not try to end it quickly — outlast it.

Mammon, The Undying — the undead lord, and a straight sustained-damage race. Bleeding and damage-over-time builds shine here because the fight rewards total damage dealt over the whole encounter rather than burst windows. If your build is all burst, this is the lord that exposes it.

Phlegethon, The Otherworldly — the frost lord. Slows and freezing zones shrink your movement options, which turns every other lord’s mechanics up a notch. Against Phlegethon, Movement Focus and any slow-resistance you can find are defensive necessities.

What to bring into the gauntlet

One armor-break source. Lucifer’s metal phases are the hardest wall in the game for builds without armor break.

One strong single-target skill. Every lord is a single target for most of the fight. Your horde clear does nothing here.

Movement and defense passives. Movement Focus and Defense Focus are passive investments that pay off exactly once — in the lord fights — and that once is the end of the game.

A committed element. The elemental Focus tiers are what let you actually race a lord’s damage output. A mixed build does not have the multipliers to keep up.

The one thing to remember

The demon lords are not a mechanics check — they are a build check. Each one punishes a specific deficiency: no armor break, no single target, no sustain, no movement. By the time you reach Satan, your build either covers all four or it does not, and no amount of dodging fixes a build that cannot win the damage race.
