I failed to find some useful information about what enemies are immune or may be especially vulnerable to the
Frost Bomb (Alien Hunters DLC weapon).
The Sectopod for example seems to be somewhat immune, but I think it loses one of its actions in the following turn.
I also think that the Elite Muton from Long War is completely immune, but I am not 100% sure. Maybe I just barely missed it?
So, what "Frost Bomb" immunities/vulnerabilities are there?
