Item Fires!
This is a simple mod that adds a single feature to the game: Item Fires.
Item Fires have a 1/8 (12.5%) chance to spawn in an Item Room instead of any items that would have usually spawned. When touched, they damage the player for 1/2 of a heart and additionally have a 1/4 (25%) chance to spawn a random Item Room pool item.
If an Item Room also has the ability to spawn trinkets (typically in modded rooms or that one room layout), then there is a 1/3 (33.3%) chance for all trinkets in the room to instead be replaced by 1 Trinket Fire. This trinket fire works functionally the same as an Item Fire, except it has a 50% chance to spawn a random trinket.
This mod is obviously based on the r/bindingofisaac thread in which one user got painfully trolled by a made-up "item fire"
