Duly noted. It would only be moderately cold anyway. The fact that it's a void with freezing temperatures is supposed to allude to 'absolute zero'. It won't reach 0K though. Only about 0C or 32F. The good this is that it can sort of serve as a foil to the user with the acidic semblance, with the refrigerant-based semblance user acting as a sort of mediator.

Also, one more idea for a semblance:

Light Refraction: As its name implies, the concentration of any light source within the user's vicinity can be 'bent' so that is redirected either toward or away from them. While this won't make them invisible, it does make them far harder to spot by the unaided eye, making it easier for them to blend into the shadows. Conversely, they can draw the majority of the light within a contained area toward themselves to make their visage dazzlingly, nigh-blindingly, bright.
