Hylterium dungeons: order, keys and rewards
Hylterium's MMORPG has five instanced dungeons, from Tharok's Castle (levels 10 to 25) to Dungeon 3, built for groups. You go in with a key and come out with rare ores, forge orbs and gear.
Progression order
| Order | Dungeon | For whom | Key facts |
|---|---|---|---|
| 1 | Tharok's Castle | Levels 10 to 25 | Key from hostile mobs in zones 1 to 3 and from the vote crate; an exclusive weapon |
| 2 | Darkness Dungeon 1 | Mid game | Rebuilt in May 2026: bigger, more loot |
| 3 | Nature Dungeon | Between Darkness 1 and Dungeon 2 | Added on 9 September 2026; emerald weapons, armour and resources |
| 4 | Dungeon 2 | Late game | Rebalanced loot and a cheaper key since May 2026 |
| 5 | Dungeon 3 | High-level groups | Sword fragments to forge at the spawn blacksmith; key bought with the Garde rank |
Dungeons provide onyxium, mithril and forge orbs, plus a little raw Hylterium.
Enter a dungeon
- Get a key: Perceval, the Keeper of Keys, sells them at spawn for reputation and Hyltcoins, and some drop from mobs or the vote crate.
- Use it to open a portal, from your base for instance: it leads to an instance of the dungeon for you and your group.
- Inside, find the boss key: it is not always in the same place. Dungeon 3 replaces this with its own mechanic.
Play as a group
/groupe(or/group) shares XP and shows your teammates' health.- Dungeon 3 is very hard solo: its mini-bosses, fragments and mobs are tuned for a group.
- Revive tokens from the guild shop let you get back up on the spot.
/luciolesummons fireflies that light up your surroundings, handy in dark corridors.- Helipacks are banned in dungeons.
Altered dungeons
The same dungeons, with stronger mobs and better loot. To unlock them, complete a spawn NPC's quests (more than ten), then craft the altered keys at the dungeon crafting table, inside the game's Arcanist table. They have been on the MMORPG since 8 August 2026, and on Skyblock since early September 2026.
Statistics and leaderboards
/donjonsdescribes each dungeon: possible loot, required keys./donjonstatsshows your runs: damage dealt, duration, chests opened. The summary also opens when you leave the dungeon.- Global and per-dungeon leaderboards rank the fastest runs, with your personal records.
On Skyblock
Skyblock has its own dungeons, with Alterations since early September 2026. The Nature dungeon will follow once the server is stable.
