Curse

Curse is a hidden stat that influences various things. 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

• Enemies drop more .
• 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 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.
• Jammed enemies deal 1 full heart of damage, move and shoot faster, deal contact damage if they didn't already, and have increased health approximately equal to health * 3.33 + 10.
  • The exact formula is unclear, but this seems likely to be the correct one, after some experimentation. In Chamber 1, a jammed Bullet Kin, which normally has 15 health, takes 12 shots from one of the 5-damage starting weapons, such as the Robot's Right Hand. Applying this formula gives it a new health total of 59.5. Similarly, a Red Shotgun Kin, which normally has a health of 30 (6 shots) now has 110 health (22 shots).
  • Blobulins are, comparatively, much hardier. They normally have 1 health, and they now take 3 shots. This formula would give them 13.33 health.
  • There is also a health cap, which seems to be 175 * X where X is the Chamber's floor modifier: x1 in Keep of the Lead Lord for 175 maximum, x1.3 in Gungeon Proper for 227.5, etc, so Gun Nuts and the are limited in how much health they can have.
• Jammed enemies become more common with each point of curse.
  • In a few room layouts in the Abbey of the True Gun, Forge, and Bullet Hell, certain enemies are guaranteed to be jammed regardless of curse.
  • Enemies that are normally harmless because they do not deal contact damage, such as chickens, popcorn (the small enemies sometimes left after defeating Poopulons) and the tiny blobulin spawned after killing Blobulord, will deal contact damage if jammed.
• 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.
• Players become able to enter the Demon Face without the need to hold 100 coins if they are cursed at least once.
• Veteran enemies, such as Veteran Bullet Kin, Veteran Shotgun Kin, Blue Bookllet, and Green Bookllet become more common with higher Curse.
• Lord of the Jammed spawns when the player reaches 10 curse. It cannot be killed, and continually chases the player.
