Hero or a crew with slight "Chill" mechanic#1257

First let me tell you I like the lore of this game so far, it is a bit light hearted sci-fi with some darker tones. So maybe a crew or a hero that would make other crew or heroes chill out a little, could be a nice addition.
Now to the idea for abillities for the hero: Imagine you could counter high mobility crew with throwing a huge snowball at them, what it would do is it would add a “Chill” status to the hit target making it 25-50% slower and giving the target a 50% chance to get a damage from thermal shock, either if the target was burning turn before, or if you set it on fire on the same turn. (It can also be a huge microvawe freezer. Powered by cinder.)
If it were not a crew but a hero, the second ability could be straigt out thermalshock if the target is burning or is chilled- making the chilled target burn or making the burning target chill.
