Challenge Runs

Challenge runs are a feature that was introduced in the Sealed Souls update for early access. These runs are accessed through the Seer NPC at the homebase once the player has beaten each of the ghost's that are trapped in secret rooms around the dungeon. The player is awarded 3 insight for each challenge run completed.

The player can only fight one ghost per run, they are found in a certain order starting from the Overgrown Gatehouse. They will only appear in the floors they're set in once the player has beaten that specific dungeon floor atleast 7 times.

Alchemist's Delve
"The Alchemist concocted elixers of terrible power. They will be your only defense within the dungeon."

The player has no weapons. instead, every 5 seconds your wrist slots will be filled with a random orb: Orb of Protection, Orb of Focus, Haste Orb, Orb of Obliteration. No shops or upgrades will spawn during this run.

Ascetic's Delve
"The Ascetic believed in strength through deprivation. The dungeon will leave you with empty hands."

The dungeon will not spawn items of any type, including food, upgrades, and even coins and keys. This is essentially like completing the empty belly/show off milestones at the exact same time, possibly the most difficult challenge run out of all of them.

Beserker's Delve
"The Berserker exulted in death and danger. The dungeon will have an increased enemy count."

In this run the player is locked at using the sword and knife, but also doubling the damage of both weapons. In doing so, the dungeon spawns twice the amount of enemies as normal.

Biologist's Delve
"The Biologist delighted in observing all creatures. The dungeon will contain a menagerie."

The enemies of each dungeon floor are randomized, so any enemy can appear on any floor.

Cartographer's Delve
"The Cartographer thrilled in walking untrod paths. The dungeon will be a lot larger than usual."

The dungeon will generate to be twice as big.

Gambler's Delve
"The Gambler reveled in risk. The dungeon will gift its boons at random, for weal or woe."

No upgrades or shops will spawn, instead, every boss defeated will grant the player two random upgrades.

Hunter's Delve
"The Hunter demanded only the greatest of prey. The dungeon will accommodate."

Only boss rooms will spawn.

Penitent's Delve
"The Penitent humbled himself through constant flagellation. You will be hardy, but take constant damage every few seconds."

The player is given a max health of 10 hearts, every 40 second you will take half a heart of damage, a dragonfruit will spawn in the food pedestal after a boss fight. (Upgrades that affect incoming damage will still make the player take more damage every 40 seconds.)
