Death Mode

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

Death Mode is the second gamemode introduced in the Calamity Mod, serving as an increased difficulty level to Revengeance Mode. It is activated by using the Death item, which can be crafted at any Altar. Attempting to activate it in a world without Revengeance Mode will have no effect. Death Mode can be deactivated and activated at will. Attempting to activate or deactivate Death Mode while a boss is alive will kill the player and despawn any active bosses.

General Changes

• Enemy damage is boosted by 15%.
• Bosses will randomly spawn if their respective conditions are met and if not killed once. This will be forewarned one minute in advance with a status message stating "Something is approaching...".
  • This has a cooldown of 24 minutes (one in-game day).
  • To work out which boss will be spawned, look at the table below for the first boss that hasn't been defeated. If its conditions are met, then this boss will be the one that is spawned.
  • Bosses will not randomly spawn until the player has 300 or more max HP.
  • The chance of a boss spawning is 0.002% (1 in 50,000) every frame.
    • This translates to a 0.12% chance (1 in 833.33) every second, or a 7.2% chance (1 in 13.88) every minute.
• The Nurse will refuse to heal the player if a boss is currently alive.
• All damage over time debuffs deal twice as much damage.

Environmental Effects

• While the player is in the Snow biome during a blizzard without cold immunity gear, they will be slowed down, with the slowness getting more intense the longer they remain in the blizzard. After 30 seconds the player will freeze, and then die 3 seconds later.
  • The player will be slowed and frozen at double the rate if the player is also submerged in water without wearing Arctic Diving Gear or equipment which inherits its effects.
  • The slowness effect gradually fades away over time after the player exits the blizzard. The speed it fades away can be increased by equipping cold immunity gear or by entering The Underworld. Being submerged in lava while in the Underworld increases the speed even faster.
• While in The Underworld without heat immunity gear, the player will be sequentially inflicted with new continuous debuffs every 6 seconds, in the order: Weak, Slow, On Fire!, Confused, and then Burning after a total of 30 seconds.
  • The debuffs gradually fade away over time after the player exits the Underworld. The speed they fade away can be increased by equipping heat immunity gear or by entering a blizzard. Being submerged in water during a blizzard increases the speed even faster.
• While in the Space biome, the player will be inflicted with Burning during the day and Frostburn during the night, without respective heat and cold immunity gear.
• While in water in the Jungle, the player will be inflicted with the Bleeding debuff, which remains for 5 seconds after exiting the water.
• The Underground and Cavern layers become darker the deeper the player gets. This can be mitigated with light-generating equipment.
  • The darkness is akin to light-diminishing debuffs like Darkness and Blackout, reducing the effectiveness of light sources and intensifying darkness in the absence of light.
  • The darkness begins to dissipate once the player gets near the Underworld, and starts getting progressively lighter the deeper the player gets, until it is fully dissipated by the time they enter the Underworld.
• Abyss light level requirements are increased by 25%.
• Thorny bushes inflict various debuffs depending on what biome they are in:
  • Crimson/Corrupt Thorns inflict both the Bleeding and Weak debuffs for 5 seconds.
  • Jungle Thorns inflict Poisoned for 5 seconds.
• Spikes inflict Bleeding for 5 seconds.
• Wooden Spikes inflict Venom for 5 seconds.
• Several environmental hazards occasionally spawn near the player while under certain conditions. They are disabled while a boss is alive.
  • Lightning periodically strikes while it is raining, dealing 200 damage and inflicting Electrified for 2 seconds. These lightning strikes are preceded with sparks appearing on the ground where they will strike.
  • Icicles fall from the sky during a blizzard, dealing 100 damage and inflicting Frostburn for 1 second and Chilled for 0.5 seconds.
  • Lava geysers erupt from lava in the Underworld, dealing 100 damage.
  • Brimstone Flame geysers erupt from lava in the Brimstone Crag, dealing 100 damage and inflicting Brimstone Flames for 2 seconds.
  • Sharknadoes spawn on the Ocean surface and Cthulhunadoes spawn during rain, dealing 125 and 250 damage respectively.
• Blood Moons boost all spawn rates by 400% and maximum spawn count by 900%. This effect stacks with other spawn rate modifiers.
• The Astral Infection biome decreases the effect of gravity on the player, similar to the Space biome.
  • This can be negated with a Gravity Normalizer Potion.
• The Astral Infection biome has a more intense purple haze effect on the screen.
  • This effect does not appear when in Retro or Trippy color modes.
