tModLoader - Calamity Modes Guide

Written by WesleyCody   /   Jun 27, 2020    


In this guide, I describe in detail, each of Calamity Mod's modes, what they do, and what they change.

Calamity Modes Overview



Revengeance Mode



Revengeance Mode can be activated if the current world is in Expert Mode. After opening up your starter bag, you will get an item called Revengeance, which can toggle Revengeance Mode on and off in an Expert Mode world. Additionally, this item can be crafted for free at a demon altar. Revengeance Mode is the recommended difficulty for new players.

Gameplay changes:

  • The player gains a Rage and Adrenaline meter - The Rage meter is filled up when getting hit by enemies and enemy projectiles, hitting enemies with True Melee Weapons, and wearing the Heart of Darkness or Draedon's Heart accessories. A hotkey can be pressed to activate Rage Mode once the meter is full, which boosts player damage by 50% for 5 seconds and resets the meter.
  • The Adrenaline meter is filled up over time when fighting a boss, and the meter is reset without any bonus if the player gets hit. The meter takes a total of 45 seconds to fill up, but using the Electrolyte Gel Pack, Starlight Fuel Cell, and Ectoheart will reduce the fill up time down to 20 seconds. A hotkey can be pressed to activate Adrenaline Mode once the meter is full, which boosts player damage by 150% for 5 seconds, and resets the meter.
  • Enemies drop double the normal amount of money.
  • Enemies spawn 15% more frequently.
  • Players cannot have more than 2 seconds of invincibility frames.
  • Asphalt player acceleration max is reduced by 33%.

  • Before any boss is defeated, the player takes 20% less damage.
  • Most enemies and bosses get percentages of damage reduction.

Revengeance Mode changes the way many enemies work as well.

Enemy Changes:

  • Many enemies inflict the horror or marked debuff - Horror reduces the target'a defence by 15, and movement speed and acceleration by 15%, along with making the screen darker. Marked reduces the target's damage reduction by 50%, along with tinting them purple.
