Ubers
Beyond Hell lies a second track: three Uber maps, each guarding a piece of Uber Camelot, and Uber Camelot itself, where Arthur waits in a stronger, twisted form. None of it advances your main dungeon — you always come back to exactly where you left it.
The three keys
In Hell, Morgause, Lancelot and Merlin (the story's own floor 30/60/90 bosses) may each drop their own key on death: Morgause's Key, Lancelot's Key and Merlin's Key. Put one key alone in the Puzzle Box and transmute: instead of an item, it opens that key's Uber map.
Uber maps
An Uber map is a short, finite dungeon: 10 floors, every room a fight, no events, no merchants, no rest. Monsters hit Hell-deep hard from floor 1. Floor 10 ends in that key's Uber boss — a far stronger, recolored version of the same character, never fought anywhere else:
| Key | Map | Boss |
|---|---|---|
| Lancelot's Key | The Fallen Lancelot's Hollow | Lancelot, Oathbreaker Reborn |
| Merlin's Key | The Chained Mage's Spiral | Merlin, the Unchained |
| Morgause's Key | The Orkney Queen's Rookery | Morgause, the Undying Queen |
Kill the map's boss and you always get that map's organ — Lancelot's Heart, Merlin's Brain or Morgause's Ear — then you're returned to your main dungeon, at the exact floor and room you transmuted the key from. Keys and organs are currency: they land in the Materials tab, never the bag. Dying inside an Uber map is final, same as anywhere else: there is no safety net for going in.
You can only be inside one Uber map at a time (no transmuting a second key, or the three organs, while already in one), and the waypoint doesn't work inside a map — you're here to finish it.
Uber Camelot and Arthur
Put all three organs together in the Puzzle Box and transmute: they open Uber Camelot, the same shape as the other maps (10 floors, all fights) but a notch harder, ending in Arthur, the Rotten King Ascendant — not the Arthur of floor 100, but a separate, far stronger reckoning with him.
Kill him and the account gets a permanent, stacking bonus: +All Skills, +All Attributes and +All Resistances, applied to every hero you ever set out with from then on. Every further kill ranks it up again, up to rank 10:
| Rank | Bonus |
|---|---|
| 1 | +1 All Skills |
| 2 | +1 All Skills, +1 All Attributes, +1 All Resistances |
| 3 | +1 All Skills, +2 All Attributes, +2 All Resistances |
| 4 | +1 All Skills, +3 All Attributes, +3 All Resistances |
| 5 | +2 All Skills, +4 All Attributes, +4 All Resistances |
| 6 | +2 All Skills, +5 All Attributes, +5 All Resistances |
| 7 | +2 All Skills, +6 All Attributes, +6 All Resistances |
| 8 | +2 All Skills, +7 All Attributes, +7 All Resistances |
| 9 | +2 All Skills, +8 All Attributes, +8 All Resistances |
| 10 | +3 All Skills, +10 All Attributes, +10 All Resistances |
Rank 10 is the cap: once there, Uber Camelot still drops its usual gear, but ranking up stops. The bonus belongs to the account, not to one hero — a fresh character already has it.
Killing Arthur on floor 100 of the story is unrelated: it unlocks corruption for the account, same as always. The two Arthurs are different fights with different rewards.
