Hey! Sorry I didn't clarify this earlier.Your character looks great, though I just have one question about his powers. What's the lowest he can make the temperature around him, and what sort of radius is there? Oh, and is the freezing instant, or over a few seconds?
The most he can lower the temperature by is 25 degrees. Considering that he is still weak, this would be hard to do. Without tiring himself out, he can lower it by 5-10 degrees. Without trying to lower the temperature around him, it is usually 2 degrees lower than the current temperature (think of it as a passive effect). The radius for his ability is 3 feet around him.
The freezing of materials isn't instant, and happens along the course of a few seconds. For larger objects (for instance, if he wanted to freeze over a pond) it takes longer; 30 seconds or longer. For smaller items, like puddles or glasses of water, it happens in a few seconds.
