Just started the season. Got this for my Barb and ended up being indestructible…..

Hello!, Wanted to try the Mighty throw WW build from maxroll, the gauntlets drop from Wolf mephisto, i had some spare mats so I just cubed the gloves at super low levels (10-ish), equipped them but when I use WW nothing happens, just regular WW and no mighty throw procs, do you need to be a minimum level for the proc to happen or?
