Daemonium Bestiary

Daemonium Bestiary

Know your enemy. Then harvest it.

The corridors of the Endless Dungeon are patrolled by a roster of ten custom demons, collectively the Daemonium. They appear from trial spawners scaled by player count and drop unique trophy materials.

Shared Behaviors

Every Daemonium shares a handful of mechanical tells.

• Spawn invulnerability. For the first 50 ticks (2.5 seconds) after spawning, a Daemonium plays a spawn animation and cannot be damaged. Trial spawners drop their occupants directly on top of you; do not waste your first sigil charge.
• Attack self-stun. Heavy attacks freeze the demon's movement for the duration of the animation. This is your tell and your window.
• Layered sound design. Spawn, attack, hurt, and death events stack several vanilla sounds at once. The audio is the cleanest indicator of which attack is incoming.

Fodder Tier

Daemonium Cruoris, The Blood Demon

30 HP, 5 damage. Three attacks: left claw, right claw, and a leap attack that closes a 3 to 10 block gap at 1.5× damage. The leap fires roughly 40% of the time at edge-of-melee range; bait it, sidestep it, and the demon eats 75 ticks of self-stun. Its walk/run stance shifts visibly when committing to a charge.

Drops: Gore-Clotted Fang, Tainted Flesh, Rotten Flesh.

Daemonium Pestis, The Pestilence Spider

30 HP, 6 damage, negligible armor. Two attacks: a fang bite and a shadow lunge that dashes through the gap and bites again at the far end. Both inflict Poison II for 5 seconds. Individually fragile, but they swarm; the poison stack will kill you faster than the bites do. Bring milk or a flask.

Drops: Venomgland Sac, Tainted Flesh, Spider Eye, String.

Daemonium Rancoris, The Spite Phantom

The dungeon's common ranged threat. Most archery-flavoured trial spawns produce Rancoris; roughly one in ten produces a Slime of Vitae instead.

Spectral ranged attacker, 45 HP, 6 damage. Two attacks: a spectral bolt (single tracking projectile, Slowness I for 3s) and an ectoplasmic burst (AoE at the target's feet, 1.5× damage, Slowness II for 5s). Will kite across the room; close the gap or you take the burst point-blank.

Drops: Ectoplasmic Residue, Tainted Flesh, Arrows, Bone.

Daemonium Animaris, The Soul Wraith

Flying, partly-phasing, 30 HP, 7 damage. Drifts through walls and through your guard alike, charging straight through targets and reorienting on the other side. Awkward to hit cleanly. Its low health is the main mercy.

Drops: Animus Mote, Phantom Membrane (rare).

Slime of Vitae

Sometimes summoned in place of Rancoris from the same trial spawners.

A blood-red slime of coagulated Essentia Vitae. Touch slows; death detonation deals raw magic damage in an AoE. Magic-immune; bring physical attacks. If four small slimes gather, they merge into a larger variant. Kill them faster than they clump.

---

Standard Tier

Daemonium Voraxis, The Voracious Oni

60 HP, 8 damage, 6 armor, 0.28 movement. The first demon that genuinely tanks. Two attacks: left slash and right slash, both apply Hunger II for 5 seconds. Extended Voraxis fights force you to eat mid-combat, which is exactly when their friends close in.

Drops: Hollow Gut, Tainted Flesh, Leather, Raw Demonite (rare).

---

Elite Tier

Daemonium Corrodis, The Wither Knight

100 HP, 8 damage, 15 armor, 0.28 movement. Three attacks: a sweep, a double sweep, and a two-phase slam with wider arc. Every hit applies Wither, and the slam adds Weakness for 5 seconds. Armor-piercing weapons or anointments are the cleanest counter.

Drops: Blight Marrow, Raw Demonite, Tainted Flesh, Bone, Wither Skeleton Skull (rare).

Daemonium Fervidis, The Undying Brute

150 HP, 12 damage, 10 armor. Three modes: decay swing (basic melee), revenant smash (leap slam at 1.5× damage), and the bear stance, a defensive posture granting Resistance II for 2.5s and near-invulnerability. Wait the stance out; do not waste cooldowns into it.

Drops: Revenant Plate, Gore-Clotted Fang (rare), Raw Demonite, Tainted Flesh, Gold Ingot.

Daemonium Doloris, The Wendigo of Pain

Also the species of the dungeon boss; see "The Foreman" below.

200 HP, 10 damage, 8 armor, 0.24 movement, two-phase. Phase 1 cycles Combo 1, Combo 2, and a leap slam at 1.5× damage. Below 50% HP, Phase 2 opens Combo 3 (upward slash + spin, applies Wither II) and the ghost howl, briefly phasing Doloris out of reality before counter-attacking. The phase transition has a distinct sound layer; back off when you hear it.

Drops: Frozen Marrow Shard, Ectoplasmic Residue (rare), Raw Demonite, Tainted Flesh, Ice.

The Foreman

The Foreman is a unique Daemonium Doloris variant that spawns once per dungeon, inside the sealed Foreman's chamber. Vital statistics:

• 600 HP, 25 damage, 16 armor, 8 armor toughness.
• Hosts a vanilla boss bar while alive.
• On death, drops a clutch of Mine Dungeon Keys, which open the deeper sealed doors inside the Mines. The trial spawners inside the Mines can drop them too.

Treat it as a boss fight, not an elite encounter. Bring sigils and sentient weaponry; attempt it under-equipped at your peril.

Apex Tier

Daemonium Ignis, The Fire Demon

60 HP, 6 damage, 7 armor, fire-immune, permanent Slow Falling. Three attacks chosen by range and arc:

• Fireball at long range: Large Fireball at 1.5× velocity.
• Ground Slam when in front and within 4.2 blocks: AoE at your feet, ignites for 5s.
• Sword Slash at other ranges below 25 blocks: Slowness IV for 3s, then four hits over 16 ticks, each resetting your i-frames and refreshing fire. The slowness locks you in the multi-hit.

Stay off-arc when close. Stay behind cover when far. Anywhere in between is the kill zone.

Drops: Cinder Heart Fragment, Tainted Flesh, Blaze Rod (rare).

Daemonium Glaciaris, The Ice Colossus

The single most dangerous creature in the dungeon.

250 HP, 10 base damage, 8 armor, 0.2 movement. Six attacks:

• Basic ice projectile: 10 damage, Slowness II for 2s.
• Ice Beam: channelled ~5s, 0.25 damage/tick + Slowness III refresh. Locks disengagement.
• Rose Toss: thrown ice rose, 10 damage, Slowness III for 3s.
• Shards Burst: close-range AoE, 15 damage, Slowness IV for 3s.
• Wall Summon: temporary ice wall and ice golem as area denial.
• Mist Phase: 20 seconds of full invulnerability while repositioning.

Drops the rare Permafrost Core required for the most powerful Hellfire Forge recipes, including the Sigil of the Damned. Plan the fight around the mist phase.

Drops: Permafrost Core, Frozen Marrow Shard (rare), Raw Demonite, Blue Ice.
