The Wheel of Adaptation 

The Wheel of Adaptation is worn on the helmet slot, you need to take a damage type 3 to 16 times before adapting to it which makes you heal back the damage taken from that damage type. The wheel is crafted by surrounding a nether star with gold blocks:

Here's a sample of the Adaptation Process and how the heal back works:

This add-on is also compatible with Novelty API and has a slightly different system. Wearing the wheel using the Hat Slot with Novelty API will give you the Adaptation Process but will not heal back, just like in the manga where Sukuna bears the  process of Adaptation but does not gain it's abilities.
