Curse

Curse is a hidden stat that influences various elements of a Gungeon run. Curse is tracked separately for each character if playing in co-op.

Cursed enemies (and their attacks) are referred to as "Jammed", and take on a glowing red and black color.

Effects of Curse

• Jammed enemies start appearing and become more common with each point of curse.
  • Jammed enemies drop more .
  • Jammed enemies deal 1 full heart of damage (but still deplete 1 armor as usual), move and shoot 50% faster, have their cooldowns reduced by 33%, deal contact damage if they didn't already, and have increased health equal to health * 3.5 + 10.
  • Jammed enemies move slightly faster.
  • Keybullet Kin and Chance Kin can be jammed and upon killing will drop two items.
  • Jammed enemies have a maximum health of 175 * X, where X is the floor's health scaling multiplier.
• Veteran enemies, such as Veteran Bullet Kin, Veteran Shotgun Kin, Blue Bookllet, and Green Bookllet become more common with higher Curse.
• Jammed bosses can appear, which behave like regular bosses but deal a full heart of damage with every attack and have their health modified by the formula health * 1.2 + 100.
• The chance to receive a reward upon clearing a room decreases with each point of curse, similar to how Coolness increases said chance.
  • The chance starts off at (1+[coolness]-[curse])%, and for every room cleared without getting a reward, it increases by a fixed amount (approximately 9% in a normal single-player run), up to a maximum of 85% on floor 1, or 80% on any other floor. When a reward is dropped after clearing a room, it goes back to (1+[coolness]-[curse])%.
    • The effect of negative drop chance is unknown.
• The chance to receive ammo upon clearing a room increases with each point of curse.
• The chance of a chest becoming a Mimic increases by 2.1% for each point of curse.
• The chance of a chest having a fuse when discovered increases by 5% for each point of curse.
• Players become able to enter the Demon Face without the need to hold 100 coins if they are cursed at least once.
• Lord of the Jammed spawns when the player reaches 10 curse. It cannot be killed, and continually chases the player.

Past 10 curse, the odds of enemies and bosses being jammed stays at 50%, but other effects continue to increase linearly.

Decreasing Curse

Curse can be decreased by:

• Dropping any cursed item/gun.
• Praying at the following Shrines:
  • Cleanse Shrine (sets curse to 0)
  • Dice Shrine granting Cleansed (removes up to 10 curse)

Notes

• Stealing from Cursula will only increase curse by 1.
• Curse carries over to the Past.
• In a few room layouts in the Abbey of the True Gun, Resourceful Rat's Lair, Forge, and Bullet Hell, certain enemies are guaranteed to be jammed regardless of curse.
• Even enemies that are normally completely harmless, such as chickens, popcorn (the small enemies sometimes left after defeating Poopulons) and the tiny blobulin spawned after killing Blobulord, can be jammed and will deal contact damage if jammed.
• At the above-mentioned rates:
  • All chests will have fuses at 20 curse.
  • All chests will be Mimics at 47 curse.
  • The player will receive no rewards for clearing rooms at 100 curse.
• Although it is easy to make the connection, coolness and curse are not related in any way (unless the player has the Sixth Chamber), nor do they cancel one another out.
• It is possible to have negative values of curse by dropping a cursed item after using the Cleanse shrine.
  • Using the cleanse shrine with less than 0 curse will pay you 5 for each negative point and set curse back to 0 again.
• Cursed items emit black smoke-like particles before being picked up.
  • The particles can be temporarily stacked and made more dense by slowing time with the Super Hot Watch or even simply by pausing the game.
