Boss Rush is an alternative game mode that is accessible in the starting area of the Prisoners' Quarters. In this mode the player can fight bosses back-to-back with items they receive throughout the trials, without traveling through the regular biomes. It has 4 trials, with only the first being unlocked at the start. Completing a trial will unlock the next one.

General[]

Access[]

To access the Boss Rush, one needs to encounter at least 3 bosses (one Tier 1, one Tier 2, and one Tier 3). To access the 3rd & 4th trials that contain 5 bosses instead of 3, one needs to encounter at least 5 bosses (two Tier 1, two Tier 2, and one Tier 3). If the player has encountered additional bosses, then those can be randomly chosen as a Tier 1/2/3 boss during a trial.

Gameplay[]

Stat-Stone

Stat-Stone-Brut

Stat-Stone during a trial after choosing Brutality

At the start of a rush, there is a choice between Brutality, Tactics, and Survival in the form of three Stat-Stones. Choosing one will automatically give the player stats relevant to the chosen colour and supply the player with 3 choices of relevant builds at the start of the trial in the form of tubes. Once a colour is chosen, the player won't be able to change the colour and will only find items with that main stat colour during the run (the only exception being the first colourless altar and any legendary ones). Interacting with a second and third Stat-Stone will increase the stats of the player.

Each boss drops loot in the form of two items (one weapon and one skill) and a fixed amount of gold. The last boss will only drop cells (around 150-300, depending on the trial), which then can be invested into the Legendary Forge at the end of the run. Cells don't carry over outside Boss Rush.

These items are disabled during Boss Rush:

Transition Rooms[]

These will be present in every transition room:

  • Guillain: Players are able to choose mutations in every transition room during a trial.
    • The first reroll will always be free.
    • Though rerolling mutations further will cost gold.
    • Rerolling will never cost money in the first Guillain.

These will be present in every larger transition room (after every boss in the 1st & 2nd trial and after every two bosses in the 3rd & 4th trial):

  • Stat-Stone: Interacting with it gives the player more stats.
  • Item-Altar: A two-choice-altar (with a weapon and a skill) will appear at the beginning of the transition area.
    • A colourless three-choice-altar (with one guaranteed weapon & skill) will appear instead at the beginning of a run.
      • *** The colourless altar can hold items from other colours.
    • If the previous boss has been slain flawlessly, then a legendary three-choice-altar (with one guaranteed weapon & skill) will appear instead.
      • This only happens in the 2nd & 4th trial (possibly due to a bug).
      • The legendary altars can hold items from other colours.
  • The Blacksmith's Apprentice: Players are able to upgrade items or reroll their affixes.
  • Shops: Two shops (weapon & skill) will provide the player with more gear. The shops default to coloured shops even if old shop category modifier is on in Custom Mode.

At the end of a run:

  • Legendary Forge: After the run has been completed, the player gets the choice to invest their Cells into the Legendary Forge. All cells not invested will be lost.
  • Loot: A chest that contains rewards is located at the end of the last transition area, alongside the Mentor Knight NPC.

Mechanics[]

General[]

A Boss Rush trial is not counted as a "game", hence the total number of games and death count will remain unchanged during attempts. If the game is exited during or in between fights, the player will reset in front of the trial door as if the run was lost.

Trials[]

There are 4 different trials in Boss Rush, with each being harder than the previous. A 3 bosses and 5 bosses trial, without and with modifiers. The player will be fighting alternative versions of bosses with extra abilities in the trials with modifiers.

  • Trial 1:
    • 3 bosses back-to-back
    • One Tier 1, Tier 2 & Tier 3 boss
  • Trial 2:
    • 3 bosses back-to-back with modifiers

  • Trial 3:
