What drops in Underworld Gate in Dungeon Lootr?
Quick answer: Underworld Gate is Dungeon Lootr's late-game dungeon with Nightmare and Endless difficulties. Its Scarlet Knight drops Exotic Ore, and its secret boss Igris — found in Nightmare and Endless — drops Exotic Shattered Armor at 8%. On Nightmare it is also the source of the Underworld Glaive, the 1% class item for Dreadlord.
What Underworld Gate is
Underworld Gate is one of the named Nightmare-tier dungeons in Dungeon Lootr — RoboLibrary lists it alongside Frostspire Bastion as the go-to Nightmare content for endgame farming. It runs the standard loop of zones, altars and a final boss, but with two differences that make it a farming destination: difficulty tiers above Hard (Nightmare and Endless), and a secret boss that only appears in those tiers.
Nightmare-tier runs here feed several endgame goals at once — All Things How notes that a single Underworld Gate Nightmare progression can simultaneously progress the Devil Hunter title's Exotic Ore requirement and other Exotic material goals if you are building gear at the same time.
Who drops what: Scarlet Knight, Igris and the glaive
| Encounter | Where | Drop | Rate |
|---|---|---|---|
| Scarlet Knight | Underworld Gate | Exotic Ore | See note below — sources differ by route |
| Igris (secret boss) | Nightmare & Endless | Exotic Shattered Armor | 8% |
| Igris (secret boss) | Nightmare & Endless | Exotic Essence (related drops) | not published |
| Dungeon completion | Underworld Gate Nightmare | Exotic Essence | 5% on completion |
| Dungeon boss | Underworld Gate (Nightmare) | Underworld Glaive (Dreadlord class item) | 1% |
The Exotic Ore rate needs a careful note. Maxbit's guide gives 35% for Exotic Ore from Igris in Challenge Mode (wave 30+) and 15% from Underworld Gate drops; All Things How's walkthrough attributes the drop to the Scarlet Knight in Underworld Gate and requires 10 Ores for two Exotic Ingots. The honest reading: Exotic Ore comes from Underworld Gate encounters including Scarlet Knight, with different rates depending on the route (Challenge Mode boss vs dungeon completion vs direct drops). We list all three rather than pretend one number is settled.
The Igris secret boss: how he fits in
Igris is Underworld Gate's secret boss, appearing in Nightmare and Endless modes. Maxbit and Hi Tech Gazette both document the same signature drop: Exotic Shattered Armor at an 8% chance per Igris kill — the material needed for class quests. Because it is a secret spawn rather than the guaranteed final boss, an Underworld Gate farming loop means clearing the dungeon repeatedly and treating every Igris appearance as a bonus 8% roll.
For context on why players tolerate that grind: Exotic Shattered Armor is a class-quest material, and the alternative Exotic sources are much narrower — Exotic Essence comes at 5% per Nightmare completion here or 30% from any Challenge Mode boss, and Exotic Ore is covered above. Underworld Gate is the only place that touches all three at once.
Why Dreadlord mains live here
If you are chasing the Dreadlord class, this dungeon is your home. RoboLibrary's tier list documents the obtainment: the Underworld Glaive class item drops at 1% from Underworld Gate on Nightmare — one of the harshest drop rates in the game, but the only confirmed route to the class item besides crafting. Dreadlord itself sits in the S tier of Pro Game Guides' Update 1 ranking thanks to 500 base HP, full-invincibility Crimson Rush and a Dread Vortex with Parry frames plus knockback immunity.
Practical farming tips, assembled from the sources above: run the highest difficulty you can clear reliably rather than the highest available — a slower run that always finishes beats a faster one that wipes and forfeits loot; and if you are also progressing the Devil Hunter title, combine the Exotic Ore goal with these runs so one farm feeds two grinds.
Frequently asked questions
- Where is the secret boss in Underworld Gate?
- Igris is the secret boss of Underworld Gate and only appears in Nightmare and Endless difficulty. Both Maxbit and Hi Tech Gazette list the 8% Exotic Shattered Armor drop from this encounter.
- What is the drop rate of Exotic Shattered Armor?
- 8% per Igris kill in Underworld Gate Nightmare or Endless, confirmed by two independent guides (Maxbit, September 7, 2026 and Hi Tech Gazette).
- How do I get the Underworld Glaive?
- It is the Dreadlord class item and drops at 1% from Underworld Gate on Nightmare difficulty, according to RoboLibrary's verified tier list. Crafting with boss fragments is the alternative route.
- Is Underworld Gate or Frostspire Bastion better for farming?
- They target different materials: Underworld Gate covers Exotic Ore, Shattered Armor, Essence and the Dreadlord glaive; Frostspire Bastion is the only source of Devil Hearts for Awakened Devil EX and the Devil Hunter title. Endgame players rotate both.
- What difficulty should I run Underworld Gate on?
- The highest one you can clear reliably. Nightmare unlocks the Igris secret boss and the glaive drop; Endless exists for extended runs. Dying still forfeits un-extracted loot, so an unfinished Nightmare run is worth less than a completed one.
