The Calamity Mod also changes multiple vanilla item recipes. To see those, click here.
The changes listed here occur as long as the Calamity Mod is installed, and are not restricted to any modded difficulty modes. See the Revengeance Mode or Death Mode pages for changes that occur exclusively within those modes.
Starting[edit | edit source]
In every new player's inventory, there will be a Starter Bag, the Iron Heart, and the Revengeance. The Starter Bag contains numerous useful items and can be opened to help speed up the beginning of the game. The Iron Heart and Revengeance items, only usable in Expert Mode, will toggle their respective difficulty modes when used. Inside the Starter Bag are also the Death and Defiled Rune items, which each activate more challenging yet rewarding difficulty modes that can be toggled on and off, but only while Revengeance Mode is active.
Progression[edit | edit source]
The Calamity Mod makes heavy adjustments to the progression of Hardmode, removing many restrictions on the order in which bosses must be fought. In vanilla Terraria, many Hardmode bosses require other bosses to be defeated before they can be fought, creating a linear sequence of progression. Calamity introduces several means through which bosses can be fought "out of order", which greatly increases the player's choices and freedom during Hardmode.
- The Steampunker NPC is now available as soon as Hardmode begins, removing the prerequisite of having to defeat a Mechanical Boss.
- Life Fruits are also available from the start of Hardmode, without the need of defeating a Mechanical Boss.
- The Portabulb can now be crafted to summon Plantera, meaning that the Mechanical Bosses do not need to be defeated in order to fight Plantera.
- The Temple Key and a variant of the Lihzahrd Power Cell are now craftable with early-Hardmode materials, meaning that Plantera does not need to be defeated in order to enter the Jungle Temple and fight the Golem.
- Using an Eidolon Tablet, dropped by the Eidolists found in the Dungeon and the Abyss, will summon the Lunatic Cultist regardless of whether or not the Golem has been defeated. Eidolists begin spawning as soon as Hardmode begins, meaning that the Lunatic Cultist, the proceeding Lunar Events, and the Moon Lord can all be fought at any time after defeating the Wall of Flesh.
Drops[edit | edit source]
World Generation[edit | edit source]
Treasure[edit | edit source]
The mod generates many structures containing certain items normally exclusive to different points of progression, including hardmode.
- Evil Islands will be comprised of the evil biome opposite to the one chosen upon world generation. The corresponding Biome Chests are on these islands as well.
- Some planetoids contain Enchanted Sword Shrines.
- The Ice Bio-center Lab generates with either the Arctic Diving Gear, Blizzard in a Balloon or the Frozen Turtle Shell.
- The chests in the Brimstone Crag contain several treasures:
Items sold by Town NPCs[edit | edit source]
Certain items with different requirements in progression are made alternatively available through Town NPCs. Clentaminator solutions also cost 5 , as opposed to the original price of 25 .
Mechanics[edit | edit source]
Damage[edit | edit source]
- Crystal Bullet shards will deal 40% less damage. The damage penalty takes the gun's base damage into account.
- Hallowed Stars from Holy Arrows will deal 30% less damage. The damage penalty takes the bow's base damage into account.
- Chlorophyte Bullets will deal 20% less damage. The damage penalty takes the gun's base damage into account.

- The Worm Scarf only provides a 10% damage reduction instead of 17%. This brings it in line with the Bloody Worm Scarf.
- The Frozen Turtle Shell only provides a 15% damage reduction when under 50% health instead of 25%.
Difficulty Indicator[edit | edit source]
The Difficulty Indicator is a UI element that is located to the left side of the player's minimap while the player's inventory is open. It holds three rune slots that help to indicate which Calamity Mod world difficulties are currently enabled:
- If the Difficulty Indicator is empty, it means the world does not have any Calamity Mod difficulties enabled.
- If the top rune is active, it indicates that either Revengeance Mode or Death Mode is currently active. The Revengeance Mode icon is a red skull while the Death Mode icon is a red pentagram.
- If the bottom-left rune is active, it indicates that the Defiled Rune is currently active.
- If the bottom-right rune is active, it indicates that Armageddon is currently active.
Minions[edit | edit source]
- Minions are changed to automatically adjust their damage whenever the player's equipment is changed, no longer needing to be re-summoned in order to take effect.
- All attacks labeled as summon will deal 50% less damage if the player is holding a weapon belonging to a different class.
Modifiers[edit | edit source]
- Defensive accessory modifiers now also increase damage reduction and gain more defense in Hardmode and Post-Moon Lord, with rarer defense modifiers granting a larger bonus.

- Lunatic Cultist's health in Normal Mode and Expert Mode is increased (32,000 to 38,400 / 40,000 to 48,000).
- Multiplayer scaling of bosses' health is decreased. Calamity takes the boss's health on multiplayer and multiplies it by a scalar to reduce it.
- For two players, 82% of health is contributed per player, totaling 164% of base (singleplayer) health.
- For three players, 72% of health is contributed per player, totaling 216% of base health.
- For four players, 64% of health is contributed per player, totaling 256% of base health.

- Boulder traps deal less damage (140 / 182 / 227 / 261), but inflict Broken Armor for 10 seconds on hit.
- Explosive traps deal much less damage (350 / 450 / 517), but inflict On Fire! for 10 seconds.
