I'll try to think for other types:
Name: Air Conditioner
Ability: Changing the aura to a layer that cools the body when it's hot or warms the body when its cold
Drawbacks and limitations: It works until the body runs out of nen energy.
Uses: When the ac is down, I can use my nen to keep my body cool.
Name: Self Puppet
Ability: To take control of my own body as a puppet when I can't move it on my own.
Drawbacks and limitations: Exhausts the body by making it move beyond its limit. Using it does not make the body rests and doesn't make the pain go away.
Uses: Can be used to move the body when paralyzed or when it hurts to move on my own and therefore force myself to move.
Can't think for Enhancement or Specialization right now.
Not sure that it says that the computer is always the newest at the time lol. I guess it can be interpreted that way although I would rather have a better translation.
