The Calamity Mod changes several aspects and details regarding vanilla Terraria content, ranging from the order in which bosses can be fought in to which items are sold by NPCs.

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

In every new player's inventory, there will be a Starter Bag. The Starter Bag contains numerous useful items and can be opened to help speed up the beginning of the game.

Progression

The Calamity Mod makes heavy adjustments to the progression of Hardmode, removing many restrictions on the order in which bosses must be fought, and also (if the Early Hardmode Progression Rework configuration option is enabled) changing the obtainment method of early-Hardmode ores and Hallowed Bars.

Non-linearity

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.

Ores and the Mechanical Bosses

If the Early Hardmode Progression Rework config option is enabled, the unlocking methods of early-Hardmode ores, as well as the Mechanical Bosses' stats, will be dramatically altered:

  • Defeating the Wall of Flesh will now cause Cobalt Ore and Palladium Ore to be spawned in the world and will allow any of the Mechanical Bosses to randomly spawn at night. These effects no longer occur when Demon/Crimson Altars are destroyed.
  • Crimson and Demon Altars will now drop 4 Souls of Night when broken.
  • The Pwnhammer and Hammush will now state that Crimson and Demon altars will not spawn ores when broken and that mechanical bosses spawn ores instead.
  • The Twins, The Destroyer, and Skeletron Prime now have dynamic stats and change depending on which Mechanical bosses the player defeats first.
    • If no Mechanical Bosses have been defeated:
      • The Mechanical Boss' base HP and damage are decreased by 20%
    • If one Mechanical Boss has been defeated:
      • The Mechanical Boss' base HP and damage are decreased by 10%
    • If two Mechanical Bosses have been defeated:
      • The Mechanical Boss has no stat adjustments.
  • The first mechanical boss defeated will now cause Mythril Ore and Orichalcum Ore to be spawned in the world.
  • The second mechanical boss defeated will now cause Adamantite Ore and Titanium Ore to be spawned in the world.
  • The third mechanical boss defeated will now cause Hallowed Ore to be spawned in the Underground Hallow biome.
  • All mechanical bosses will drop Hallowed Bars once they have all been defeated.

Drops

  • All Vanilla Treasure Bags are changed to follow the 'Calamity style' of dropping their main weapons or items. This refers to each item having an independent and equal chance to drop but, if none of them drop, then one is chosen at random and forced to drop. This ensures at least one main item per Treasure Bag.
  • Many Calamity enemies can drop Vanilla items:

World Generation

  • The Jungle Temple's generation has been changed to guarantee a large arena to fight the Golem in.

Treasure

The mod generates many structures containing certain items normally exclusive to different points of progression, including hardmode.

Mechanics

Damage

  • 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.

Point-Blank Damage

  • Most Ranged weapons, excluding Flamethrowers, can perform Point-Blank shots that multiply all damage dealt by the weapon's inital projectiles by x1.5 so long as the projectile hits the target within 12 frames of being fired. Ranged damage projectiles spawned by on-hit effects, such as from an accessory, cannot recieve the damage multipier even if they hit the target within the 12 frame window.
    • Ranged weapons that can perform Point-Blank Damage will mention so in their tooltips.

Defense

Various changes have been made to vanilla's defense boosts:

Defensive accessory modifiers now scale with progression:

Modifier Hard Guarding Armored Warding
Vanilla +1 +2 +3 +4
Hardmode +2 +3 +5 +6
Post-Moon Lord +3 +4 +6 +8
Post-Devourer of Gods +4 +6 +8 +10

Some vanilla items have gained the ability to increase defense:

Additionally, Sharpening Station's armor penetration value has been nerfed from 12 to 5.

Damage Reduction

A graph displaying the relationship between the player's DR stat and the percent of damage that gets reduced in actuality.

The Calamity Mod adjusts the effective percentage of this stat for the player with a diminishing scale, with all DR reducing effects (such as Armor Crunch) being calculated after it has been scaled. NPC DR is not affected by this diminishing scaling.

The scaling formula is: 1 - 1(1 + dr)

For example, if the player has 25% DR, it will be scaled to 1 - 1(1 + 0.25) = 0.2, or 20% DR.

Various changes have been made to vanilla's damage reduction boosts:

Defensive accessory modifiers now increase damage reduction:

  • Hard increases DR by 0.25%.
  • Guarding increases DR by 0.5%.
  • Armored increases DR by 0.75%.
  • Warding increases DR by 1%.

Some vanilla items have gained the ability to increase damage reduction:

Movement Speed

Movement Speed has been reworked and will now grant proper bonuses to both player movement and flight speed.

  • The static movement cap of any boots that grant the ability to run has been removed.
  • Additionally, the maximum horizontal player speed cap has been increased from 160% to 300%.
  • All Balloon accessories now grant the player +15% jump speed instead of +30%.
  • Equipping any type of Wings will now grant the player +24% jump speed. This is added on to any other jump speed boosts the wings might have.
    • The player is granted 10% jump speed if neither wings nor balloons are equipped.
    • Flight time boosts are also now additive instead of multiplicative on top of receiving bonuses from movement speed.
  • The player's base movement speed has also been increased from 15 mph (11 tiles/second) to 23 mph (~18.667 tiles/second).

Minions

  • 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.

Environment

  • In the Snow and Ice biomes in Expert Mode, the player is inflicted with Frozen Lungs when submerged in water, draining their breath much faster; however, the water no longer inflicts Chilled on the player. This feature can also be reverted through editing the configuration options.
  • Boulder traps deal less damage (140 / 182 Expert Mode / 227 Revengeance Mode / 261 Death Mode), but inflict Broken Armor for 10 seconds on hit.
  • Explosive traps deal much less damage (350 / 450 Expert Mode / 517 Death Mode), but inflict On Fire! for 10 seconds.
  • Sandstorms cannot occur until the Desert Scourge is defeated.
  • Graveyards require 20 Tombstones to form, instead of 7.
    • The incremental pre-Graveyard screen shader begins at 17 Tombstones, instead of 4.

Velocity-Based Contact Damage

All bosses scale their contact damage based on how fast they are moving relative to their maximum velocity. The process for calculating this is explained below.

  • Each boss is assigned one of two values to be a velocity scalar; either 0.5 or 0.8.
  • The boss's velocity relative to half its maximum velocity is represented as a percentage. If it is greater than half of the maximum velocity, it is set to 100%.
    • For example, if the boss is travelling at 30% of its maximum velocity, the percentage would be 60%. However, if the boss is travelling at 70% of its maximum velocity, the percentage would be 100%, not 140%.
  • The percentage is used to find a number between the previously-assigned velocity scalar and 1.1.
    • For example, a percentage of 75%, with a velocity scalar of 0.5 would return a value exactly 75% of the way between 0.5 and 1.1, which is 0.95.
  • Contact damage is then multiplied by the number found in the previous step.

Reforge System Rework

If the Remove Reforge RNG configuration option is enabled, the Goblin Tinkerer's reforge system will be entirely reworked:

  • All modifiers are grouped into categories that consist of 6 tiers, categories are determined by weapon damage type and ability to receive certain modifiers over others.
  • Each time the player reforges an item, the tier gets higher until tier 6 is reached. Reforging an item past the max tier will give the max tier modifier forever.
    • Rolling an item to tier 0 will grant a random modifier that weapon can receive.
  • Modifiers get progressively more powerful the higher the tier. Rolling an item to tier 6 will always grant the best modifier possible for its category (For example, if the Crystalline is currently at tier 5, its next reforge would grant it the Flawless modifier).
  • Weapons can no longer receive negative modifiers when reforging.
  • If an accessory has the highest tier modifier it can obtain, only the highest tier modifier can be rolled if that item is reforged (For example, if the Coin of Deceit currently has the Silent modifier, its next reforge has the potential to roll the Lucky modifier, but can not roll the Spiked modifier).
  • All weapons can now receive their class type's best modifier except for Flails, Spears, and Yoyos. Weapons that have no knockback cannot gain knockback increasing modifier bonuses. Ranged weapons that have a use time lower than 6 will not receive any speed-adjusting modifier bonuses. Mage weapons that have a mana cost lower than 5 will not receive any mana cost decreasing modifier bonuses.
  • All reforge value costs have been decreased by 50%. This includes all modifiers introduced by the Calamity Mod.
  • A full list of the categories and items associated with them can be found below:
