This technique is know throughout the universe by many species of aliens. Specifically Namekians and/or Majin beings. This technique allows the users to "refurbish" themselves to a certain extent. Limbs and appendages can be replaced if lost, bones can be healed, and internal organs can return. Let me remind you that only the two know species above can use such a technique. But the use of such a handy technique comes at a price. You must sacrifice stamina and a small amount of power per regeneration. This is only used if bones have been crushed or limbs have been lost, nothing more and nothing less.
It is used as follows:
Arms and legs: -15 stamina/-5 power
Other appendages (i.e tails, ears, and fingers): -5 stamina/-2 power
Bones: -20 stamina/-15 power
*Bones use more energy and stamina because they are a crucial factor to a beings structure. Without them, you are just a blob of skin and meat.*
*Skin cannot be regenerated using this, you must wait for the natural process of healing.*
