User blog comment:Patrick x hunter/abilities that i think work/@comment-5780397-20160119102354

1. Works perfectly.

2. From what we've seen so far, you'd need a room that exists in a totally separate dimension, like Knov's Hide and Seek or Cheetu's Tag, with precise bounds. Aside from that, it is a great and cretive ability. The onky thing I don't understand is, you said the room cannot swallow living things, so how can a human being get inside? Did you mean only the user can enter it for as long as he/she can hold his/her breath?

3. Looks a bit too strong, you might need a couple limitations, for example direct physical contact with the battery.

4. As you said, it is mainly a Transmuter ability. Keep in mind you would also be affected, unless you used Emission to generate heat far away enough from yourself.

5. I'm not sure what Nen type it would be, but anyway, it works.
