Frost blast has inconsistencies with its cool down and when throwing ice boulder it will inflict frostbite but not do damage to enemies.
I second frost blasts cool down does mess up from time to time. Its cool down won't start to go for a short while. Usually I have to hit a power or two before it starts the cool down when it gets stuck.
No that’s not it. It goes fine for a few rotations then gives me the middle finger and stops the cool down timer zeroing out for 5-7 seconds before it comes back during that time my other power started freeze up as well.
