"Do you enjoy going through hell?"

Revengeance Mode is a new gamemode introduced in the Calamity Mod, serving as an increased difficulty level to Expert Mode. It is activated by using the Revengeance item, which is added to a newly spawned player's inventory in an Expert Mode world. The item can also be crafted at any Altar and does not have any ingredients. Attempting to activate it in a Normal Mode world has no effect, and using the item during a boss battle will do nothing, with the message "You cannot change the rules right now." The transition to Revengeance Mode is reversible by using the Revengeance item again. It is further succeeded in difficulty by Death Mode.

While active, the Revengeance Mode icon will be shown on the top of the Difficulty Indicator.

When below 33% health, either attack has a chance to be replaced with an attack where the Hive Mind appears above the player and then dashes horizontally, creating many short-lived shade clouds in its wake. The same attack is never performed twice in a row.

Hungry II health increased to 117 and Leech health increased to 100. Both deal slightly more damage.

The ice bombs are no longer fired out every 10 seconds, but 2 waves are released during this attack, then it rapidly charges the player 3 times before repeating the pattern.

The Destroyer[]

HP increased to 150,000.

Can fly like a Wyvern and is near-invulnerable for 10 seconds after spawning. Body segments are larger, and gain a defense boost which increases as its health gets lower, up to a maximum of 10. Lasers move slowly when initially shot then accelerate. Speed of the Destroyer and the lasers fired increase as health lowers. Laser fire rate is reduced as health drops. Lasers are no longer fired in a random spread. Red lasers inflict On Fire! for 4 seconds. When below 85% HP, it can additionally fire green lasers which inflict Cursed Inferno for 2 seconds. When below 70% HP, it can fire blue lasers which inflict Electrified for 1 second. Probe-less parts have 10 less defense. Probes no longer drop hearts. The Destroyer gains increased aggression the lower its health, eventually being able to charge similarly to a Wyvern below 50% health. Its segments containing probes change to a purple color during this phase. The Destroyer switches to its Wyvern phase more often as its health lowers. When below 25% HP, it gains the ability to divebomb the player.

The Destroyer enrages during the day. It moves faster and more aggressively, only fires blue lasers which accelerate faster, and its body segments take reduced damage, leaving only the head and tail vulnerable.

Aquatic Scourge[]

HP increased to 136,000.

Every 11 seconds, the Aquatic Scourge performs a circle around a certain point at its path for 2 seconds before charging the player. While spinning, it fires three barrages of three sand blasts at the player. The Aquatic Scourge moves faster and vomited sand blasts and teeth travel at a greater velocity.

Enters phase 3 at 25% HP, or if Spazmatism is defeated first. In phase 3 it gains the ability to perform 2 long dashes after its normal laser attacks. Retinazer's first dash will release several homing darts that inflict 124 damage. If Spazmatism is defeated first, its laser attacks become much faster and it will dash 4 times, releasing homing darts on the first and last dashes.

Spazmatism shoots Cursed Flames faster in phase 1. Spazmatism breathes Shadowflame Breath instead of Cursed Flames in phase 2, which inflicts the Shadowflame debuff, and has 16% more damage than the Cursed Flames. Enters phase 3 at 25% HP, or if Retinazer is defeated first. In phase 3 Spazmatism performs the flamethrower attack for less time, stops to hover below the player and fire semi-homing Shadowflame Fireballs, then charges four times. If Retinazer is defeated first, the flamethrower attack no longer occurs, and Spazmatism performs five charges, with the last one traveling farther than the others. When dashing, contact damage is increased by 10%.

The Twins enrage during the day, where they move more aggressively, charge further, fire projectiles faster, and projectiles move faster. Spazmatism's flamethrower has a longer range in this state. If gravity is reversed, both Twins immediately transform into their second phases. While gravity is reversed, Retinazer's lasers move faster and fire more frequently.

The whole ray appears instantly upon being fired but does not move after being fired, and it remains for 1 second. It then releases two rows of Brimstone Darts perpendicular to it, which move slowly before accelerating. This will repeat one more time. She slows to a stop upon firing the first ray.

Prime Saw and Prime Vice are more aggressive. As limbs are killed, the remaining limbs gain increased speed and fire rate. When Prime Laser is killed, the Head begins to fire laser circles. When Prime Cannon is killed, the Head begins to fire rockets. When all limbs are killed, it spins in circles near the player before every spin attack after the first, shooting Cursed Skulls. While gravity is reversed, speed and projectile fire rate is increased. When the Head reaches 66% health, all limbs still alive are instantly destroyed, and the head itself is able to fire circles of lasers while spinning. When the Head reaches 33% health, every other spin attack is replaced with a barrage of homing Martian Missiles, the Cursed Skull attack only occurs before Martian Missile attacks, and the spin attack duration is reduced by 2 seconds.

  • "Revengeance is active." (When activated)
  • "Revengeance is not active." (When deactivated)


  • Revengeance Mode is a replacement for previous difficulty modes added by the Calamity Mod, which were known as Prepare to Die and Prepare to Cry.
  • The name of this mode is a reference to Metal Gear Rising: Revengeance. This is further supported by other references to the game within the mod, such as the Boss Health Bar, Red Sun, and the Murasama, as well as other items.
  • Several Revengeance Mode features were present in previous versions of the mod that have since been removed or changed:
    • Talking to the Nurse during a boss battle would summon a giant meteor (similar to the ones fired by The Leviathan) onto the player, instantly killing them and nearby NPCs.
    • Meteorites would not be mineable and the Reaver Shark couldn't be swung until defeating the Brain of Cthulhu or Eater of Worlds.
    • Soft caps on damage and crit chance were present, both of which have been removed, and a DR soft cap, which has been made global to all modes.
    • All attacks labelled as summon will deal less damage if the player is holding a weapon belonging to a different class. This nerf scaled with progression. This change is now global to all modes and no longer scales.
    • Revengeance Mode was a permanent change upon using the Revengeance item. It is now togglable.
  • In previous versions of the mod, Revengeance Mode would affect bosses from the Thorium Mod, and it could be disabled in the config.
