Healing Experiment

Nazarick's Healing Experiment is a form of experimentation conducted by Demiurge under Ainz's order.

Objective
This experiment was meant to test how healing magic operates in the New World compared to the world of YGGDRASIL. The underlying questions behind the healing experiment would the nutrients derived from the severed arm vanish after the subjects cannibalize it and then healed the wound afterward. Another interesting question to take note of was whether the people who ate the arms starve to death from this process being repeated over and over again continuously.

Procedures
According to Demiurge, he proceeds the experiment according to the subject's age and gender. With time, Demiurge felt that he will need to distinguish whether or not a certain species of a certain age's skin is the most suitable. Before he and his aides apply healing magic on the wounded subject, they merely allow the detached part to undergo a significant change in shape. For starters, mincing the subject's flesh then later on down the line, that fleshy part will thoroughly be preserved.

Results
When a person's arm is cut off and later healed with magic, the severed hand was said to disappear during the process.

If magic is cast after the skin has been removed, healing magic will effectively recognize it as a foreign entity. Hence, it cannot disappear even if healing magic is used. This is also the reason behind why the subjects would not die of starvation even if they ate their own meat.

In addition to that, if one aspect of healing magic is rejected by another aspect of healing magic, Demiurge noted sometimes it is as if the process conflicts with each other, causing the healing to not operate smoothly and results in a scar. Likewise, the lower the rank, the more likely it is that scars will form as time lapses.
