Difficulty

Difficulty refers to how challenging the gameplay is. There are two additional options to difficulty within the Calamity Mod, both of which increase the difficulty of the game. These difficulties are available from a separate UI element available when a player has entered a world, and are compatible with the base difficulties in Terraria.

Revengeance Mode is the intended first time experience, though this isn't a requirement for playing the mod - players should use whichever will result in them enjoying their time the most. However, players should bear in mind that Revengeance Mode's difficulty assumes they have completed the vanilla game at least once.

Difficulty Indicator

The Difficulty Indicator is a UI element that is located below the map style selector and to the left of the player's health meter while the player opens their inventory. It holds a rune slot which can be interacted to change difficulty of the world, if the player is in Expert Mode or above, and no bosses are alive.

Upon starting a new world, the icon will glow brightly until it is interacted with. When Revengeance or Death Mode are enabled, their icons will appear on the world selection screen next to the "Rename" button.

Locked	Higher difficulty modes can only be toggled in Expert Mode or above (When in Journey or Classic Mode)

Main Difficulties

Difficulty		Description
	Classic	Mostly identical to vanilla, with many vanilla changes, including Expert-exclusive items being able to be dropped in Classic Mode. Cannot enable Revengeance and Death Modes.
	Expert	Mostly identical to vanilla, with some additional vanilla changes to the difficulty that are configurable.
	Revengeance	The intended Calamity experience, introducing new mechanics, boss AI, and other assorted changes.
	Death	A more difficult challenge for those looking to prove themselves. Not recommended for a first playthrough.
	Master	Increases the aggression of all vanilla bosses as well as the health and damage of all enemies.
	Revengeance + Master	Bosses inherit all Revengeance Mode changes which are combined with select aggression changes from Master Mode. Vanilla bosses gain entirely new attacks.
	Death + Master	Combines Revengeance Master and Death Mode's changes. Vanilla bosses additionally gain minor stat buffs to some attacks.

Additional Difficulties

Not intended as distinct difficulty options but still fully accessible and freely usable by players seeking an augmented experience.

Difficulty		Description
	Journey	Allows for the research and duplication of items and enabling powers usually inaccessible to the player. Can activate Expert and Master Modes through the difficulty slider. Scaling the slider to Expert Mode or higher unlocks the difficulty indicator.
	For the worthy	Can be combined with any other difficulty mode for a significantly more challenging experience. This increases the vanilla main world difficulty by one level, allowing access to the difficulty indicator by default. Unlike vanilla bosses, all Calamity bosses gain changes on the seed by default regardless of Legendary Mode.
	Get fixed boi	Contains various elements that will be considered unfair, play at your own risk. All Calamity boss changes from For the worthy are inherited as well as adding ridiculous new ones. Revengeance Legendary Mode changes from For the worthy will still only apply with those modes both enabled.
	Legendary	Enabled by creating a For the worthy or Get fixed boi world with Master Mode selected. All vanilla bosses gain AI edits.
	Revengeance + Legendary	Inherits all changes from Revengeance Mode and Legendary Mode. All bosses from both Calamity and vanilla gain extreme new AI changes.
	Death + Legendary	Inherits all changes from Death and Legendary Mode with no additional changes.

Trivia

• The line of text "mis nuevos los gatos", a mistranslation of "my new cats" in Spanish, is defined within the Difficulty Indicator's code in order to generate the size of the description box.
• All world selection difficulty colors originate from the wiki's colors for each respective difficulty and difficulty combination.
  • Revengeance Legendary Mode's world selection color is the same color as the wiki's color for the removed Malice Mode.
  • Death Legendary Mode's world selection color is the same color as the wiki's color for the removed Defiled Rune.
