Experimental Treatment

Experimental Treatment is an unlockable passive item.

Effects

Randomly increases at least 1 and decreases 1-3 of Isaac's stats. The same stats can be increased/decreased multiple times.
Randomly increases 4 and decreases 2 of Isaac's stats.
Each increase or decrease for a stat will change it by a fixed value:
- ±1 health.
- ±1 damage.
- ±0.5 tears.
- ±0.5 range.
- ±1.5 range.
- ±0.2 shot speed.
- ±0.2 speed and maximum speed (may never exceed 2.0).
- ±1 luck.
If a stat that is already at an upper or lower limit is chosen, there is no visible effect.
Template:Transf

The stat changes are permanent and will not go away if the item is removed.

This makes the item especially useful for Tainted Isaac, since he gets to keep the stats while having the option to switch Experimental Treatment for another item and the transformation progress isn't lost in the process.

The tears up from this item is allowed to go past the normal tear cap of 5.0.

Prior to Repentance, this item's description was "All stats up... then shuffled".

Despite the item's old description, the item did not increase all stats or shuffle them.
