Revengeance Mode

Not to be confused with Revengeance, which is the item that activates this gamemode.

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. Attempting to activate it in a Normal Mode world has no effect, and using the item during a boss battle will instantly kill the player, with the death message '<PlayerName> was licked.'. The transition to Revengeance Mode is irreversible. It is further succeeded in difficulty by Death Mode.

General Changes

• Adds two new mechanics into the game, Rage Meter and Adrenaline Meter.
• All enemies drop 5 times more money.
• Enemy spawn rates are boosted.
• You deal 5% more damage but you also take 5% more damage (this is active only after your first boss kill).
• Before you have killed your first boss you take 20% less damage.
• Numerous soft caps are applied to stats, reducing their effectiveness above a certain point.
  • Damage boosts are soft capped at 85%. Any amount exceeding the cap will be 75% less effective.
  • Critical strike chance is soft capped at 75%. Any amount exceeding the cap will be 90% less effective.
  • Damage reduction is soft capped at 33%. Any amount exceeding the cap will be 90% less effective.
  • Life regen is soft capped at 18. Any amount exceeding the cap will be 75% less effective.
• Many enemies now inflict Horror and/or Marked for Death.
• All attacks labelled as summon will do much less damage if the player is holding a weapon belonging to a different class. This decrease scales as you progress (0% in Pre-Hardmode, 33% in Hardmode and 66% Post-Moon Lord).
  • If the player is not holding a weapon, summon attacks will do slightly higher damage than usual.
• Vanilla flails deal 100% more damage.
  • The Chain Guillotines only deal 20% more damage.
• Allows usage of the Defiled Rune.
• Bosses drop 11 treasure bags while Armageddon is active.
• Sandstorms will only occur after Skeletron has been defeated.

Damage Reduction

• Grants percentage-based damage reduction to many enemies and bosses, including vanilla ones. Depending on intensity, this can cause opponents to take significantly longer to kill.
  • To compensate, Ichor decreases damage reduction by 25% and Cursed Inferno decreases damage reduction by 20%; if both debuffs are applied, Ichor will take priority. Note that these effects apply to both enemies and the player.
  • In addition to this, Betsy's Curse will decrease damage reduction by 34%.
• Enemy damage reduction is not calculated in the same manner as player damage reduction:
  • Firstly, incoming damage is increased by adding one quarter of the struck enemy's defense.
  • This increased damage is multiplied by (1 minus the enemy's damage reduction).
  • Finally, this value is subtracted by half of the enemy's defense as usual.
  • This does not apply to enemies with zero damage reduction; damage is calculated normally.

Trivia

• 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, Murasama, and the flavor text for Draedon's Heart, as well as other items.
