id settle for it doing minimal cold damage over time to enemies that enter it, freezing them solid for 1 second, and slowly returning their movement and attack rate back to normal. if it redirected supers that hit it would be sweet too, like if they glanced off and away. however to balance it, the duration would have to be shorter along with a longer cool down. it would also have to take extra damage from a random element every time it was deployed. but itll never happen, so who cares about my opinion.
