Subzero

The description is lacking, has anyone tried it? Does it freeze the enemy or kill it?

i'm not sure, but i've heard rumors that it's a 1 hit ko skill

Its just like execution with 5% better accuracy can be used as a last option just to try ur luck and kill the opponent .. But believe me i had 10 % life left against one full xp behemoth in ss exp level and i used execution and it hit
What a luck
