High Peak Castle

The High Peak Castle is the last biome to traverse in order to face the final boss, one of two sixth level biomes in the game.

High Peak Castle used to be filled with visitors and guards, among the castle grounds for many purposes. However, as of everything below it, the Malaise has put a stop to all the normal activities. The last stand of the royal guard was among these grounds, but, as the current state reads, they did not make it through. While the grand statue of The King still stands, the paintings as beautiful as ever, and the hallways still quite grand, High Peak Castle has fallen from grace. It seems that no matter how hard he tried to keep royalty safe, the Malaise won in the end. Some are to say that this is called karma.

Access and exit
High Peak Castle is accessed via the Clock Room or Guardian's Haven biomes.

The exit is blocked by two locked doors that need a Castle Key each, which can be found from the Elites found in three specific areas to open the gates to the Throne Room, where the Hand of the King awaits.

Colored rooms
High Peak Castle will always have three rooms where Elite enemies reside. These Elites will always be a Slasher, two Trackers, fought at the same time, and a Thorny. The various rooms containing the Elites with the Castle Keys are engulfed respectively in a red, green and blue light.

Of the keys that they drop, only two are required to get to the Throne Room. The third key will lead to a room that contains a Scroll of Power, two randomly generated items, and the blueprint of the Boomerang. Subsequent runs after the blueprint has been obtained will contain a gem instead.

Scrolls
High Peak Castle contains 2 Power scrolls, and 2 Dual-Stat scrolls. When 3 Boss Stem Cells are active, this biome has 1 guaranteed Scroll Fragment, and when 4/5 Boss Stem Cells are active, this biome has 2 guaranteed Scroll Fragments. These cannot spawn in areas requiring the use of any runes.

Enemy tier and gear level scaling
In the table below, you will find the gear level and enemy tier of the High Peak Castle based on difficulty.

Chests and Loot

 * 1 Treasure chest behind spider rune
 * 1 Treasure chest behind ram rune
 * 1 item behind spider rune.
 * 1 item behind teleport rune.
 * 1 item behind homunculus rune.

Shops

 * 1 weapon shop.
 * 1 skill shop.

Castle Keys
The blueprint for the Boomerang can be found next to the exit to the Throne Room and requires the 3rd Castle Key. The player needs the Ram Rune and the Spider Rune to go through a very tight parkour with spikes .However it is also possible to do without the Spider Rune, but an amulet with an Affix that grants multiple jumps is required. Alternatively, the the Homunculus Rune can be used to grab it at very little risk.

Moonflower Keys
The blueprint for the Acceptance mutation (3+ BSC) can be found in a secret area where the player must have 3 Moonflower Keys. These keys must be obtained by exchanging the Gardener's Keys from the Promenade of the Condemned and going through the Ramparts, the Graveyard, and the Forgotten Sepulcher, where the keys will be hidden throughout each level in secret areas.

Enemy blueprints

 * The blueprints for Hayabusa Gauntlets and Dead Inside (4+ BSC) can be looted from Lancers.
 * The blueprints for Tornado and Soldier Resistance can be looted from Guardian Knights.
 * The blueprint for Initiative can be looted from Royal Guards.

Enemies
The table below lists which enemies are present in the High Peak Castle on each difficulty level and which blueprints each may drop. When applicable, the minimum difficulty level for blueprint acquisition is specified.

Lore
The Castle hides a number of lore rooms shining light upon the events that led to the downfall of the King and his court, as well as the whole Island.


 * The rotten corpse of a soldier is found next to a stained letter he wrote describing his symptoms. He was coughing blood, his body was so itchy he scratched himself until he bled, suffered headaches, blurred vision and felt down.

The Alchemist's room
The blue room appears to have been a laboratory for the Alchemist, granted to him by the King as a last resort option when he realized his ruthless methods were not working. Indeed, its shelves are full of various potions, vials and general scientific equipment akin to the various labs the Alchemist left all over the island. In the center of this room, where the Beheaded fights an Elite Slasher, endless rows of incubators can be seen, filled with mutated bodies. They are the same as those found in the Alchemist's Clock Tower lab, in which he was immersing infected bodies in an experimental solution in hopes of finding a cure to the Malaise.

It is unclear whether the Slasher enemy was a result of the Alchemist's experiments or if it is just another Malaise-infected character, but the fact that it is in the Alchemist's Room suggests it could be the case.

The Human-Plant room
The green room is host to a variety of plant-like structures, and its walls, floors and ceiling have been colonized by vines. In the center of this room, the Beheaded fights an Elite Thorny in front of a hybrid human-plant character who seemingly broke out of its incubator. This hybrid is the result of crossbreeding experiments by the Alchemist, in which he tried to administer plant extracts to a human "volunteer".

While the Alchemist reports that the experiment was a failure and that the subject did not survive, the fact that the incubator is broken and that the room has been invaded by plants suggest the hybrid did not actually die, and wreaked havoc in this part of the Castle.

It is unclear whether the Thorny enemy was a result of the Alchemist's experiments or if it is just another Malaise-infected character, but the fact that we fight it in this room and that the spikes on its back resemble the thorns of a rose (from which the hybrid seems to have sprouted) suggest it could be the case.

The Torture room
The red room appears to have been a torture chamber, as evidenced by the various torture instruments scattered on the floor and hanging from the ceiling. In the center of this room, the Beheaded fights two Elite Dark Trackers in a pool of blood flowing from a fountain, with what appears to be dismembered bodies and skeletons hanging from the ceiling. There is currently no lore in the game explaining the purpose of this Torture Room. It is unclear if it was used before or after the Malaise outbreak and the Island's downfall.

Trivia

 * In earlier versions of the game, this biome was just named The Castle.
 * The paintings in the Castle depict the various NPC's of the game, such as the Tutorial Knight, the Collector and others:
 * There is a painting of a mariner with tentacles for limbs and one red glowing eye hidden under a hood. This character was an NPC, now removed, found in the Pier with the purpose of announcing the player that "your vessel hasn't docked yet" as to intend that there is currently no content after the Pier. He would've then proceeded to kill the player with one of Conjunctivius' tentacles, effectively counting the run as completed.
 * A painting of the island Dead Cells itself takes place on is present.
 * A room bigger than the usual with a giant painting of the Giant when he worked as a royal guard for the King.
 * There are also many paintings with easter eggs and references to other media. These include:
 * A parody of the famous painting The Scream.
 * A portrait of Alucard from Castlevania: Symphony of the Night.
 * A portrait of the main characters from Nier: Automata.
 * A portrait of The Knight, main character from Hollow Knight, another Metroidvania-type game.
 * A picture of a bonfire with a curved sword embedded in it, clear reference to the bonfires from the Dark Souls franchise;
 * Landscape paintings of the Obsidian Woods and Magaari Ember Highlands, from the game Duelyst.
 * A landscape of a firewatch tower, in reference to the game Firewatch.
 * The titular sword from the game Transistor.
 * A painting of a boy walking into a culvert/cave, from the Netflix series Dark.
 * A painting of the Estate from the game Darkest Dungeon.
 * A picture of Solaire of Astora, character also from Dark Souls, in his trademark pose "Praise the Sun!".
 * A picture of Stilgar, from the 1991 game Dune.
 * The fact that there are paintings of characters from the franchises of Castlevania and Dark Souls is probably a joke about Dead Cells being a Metroidvania that shares a similiar combat system with Dark Souls.
