• Coolness increases as curse increases. Coolness decreases the cooldown of active items and increases the chance of items dropping upon clearing a room.*
• 2 points of coolness are granted per point of curse.
• Prevents the usual curse penalty towards getting a room clearing reward.
• Increases curse by 2. Due to the nature of the item, effectively gives 4 coolness.

• Hellhole - If the player has [奇点] , [奇点] spawns a hell portal that sucks enemies in and deals high damage.
• Just Like The Real Thing - If the player also has [射蛆] , [射蛆] 's bullets will behave like those of the [射蛆] enemy , splitting into wavy bullets upon hitting a wall or enemy.
• Pitch Perfect - If the player has [干草叉] , the [干草叉] fires green fireballs that set enemies permanently aflame.
• It is sufficient to kill just one jammed Trigger Twin in order to unlock the item. Killing minibosses, such as Fuselier , while they're jammed, will also unlock the item.
• Outside of room clear rewards, this item does not negate the other effects of curse. Jammed enemies will spawn at the rate of your current curse, mimic chances will be increased, and so forth.

• Unused: Blastin’ Heck - If the player has [见鬼冲击波] , it causes an unknown effect.
• The appearance of the item is a reference to the number 666 , identified as "the number of the beast" in the Book of Revelations of the Christian Bible and widely associated with evil and the devil.
• The item is also a reference to the sixth chamber within the game, Bullet Hell .
• Defeating the Paradox Lich from the Gunslinger 's past counts as a Jammed boss for the purpose of unlocking this item.
• If you defeat the Advanced Dragun that isn't jammed but the first stage of the Dragun is jammed, you will not unlock this item.
• This item has a chance to be sold by Cursula , as buying her stuff increases curse.
