Thank you for the post , Solved my question for Cooldown difference between Hj and Glac, . Which is one '

Also you seemed to have forgotten the L.1 interval with Glacian, Which is a passive called. "Ice Gauntlet"

"A ball of ice that damages the target with a chance to reduce armor by 5% "

Im not sure if its a L.1 passive or L.5 being the fact that i currently have him at lvl 8 with this effect,
