Item
Experiment X
Consumable Rare
A rare Experimental set consumable exclusive to The Lab chapter. Its effects are listed as unknown in the wiki — this is one of the more mysterious items in the game, with no documented mechanics beyond its chapter availability. Worth picking up in The Lab if you encounter it, but prepare for the unexpected.
The ability ID cm_ExperimentX suggests its effect was internally designed and implemented but never fully documented publicly. The Lab is the zone associated with experimental and unpredictable effects, making this item thematically consistent even if its mechanics aren't transparent. It may apply random mutations, transform your character, or have a run-altering effect that resists easy categorization.
Part of the Experimental set, which suggests it may pair with other Lab-exclusive items for set bonuses. Use it in The Lab when you have a comfortable run with enough resources to absorb an unknown result. If you're in a precarious position, hold it until conditions are more stable — a potentially destabilizing effect on a teetering run can be costly.
