Winterheart + Vessel of Vinktar + Three Dragons Mask COMBO

Im trying to self freeze with winterheart.
I saw another build on it but I wanted to try something different.

Im testing out Winterheart + Vessel of Vinktar (self shock) and Three Dragons Mask ( shock becomes freeze ) BUT : IT ISNT WORKING. Why am I not freezing myself?

Because vinktar doesn't do any lightning damage, it just shocks. The only way to make this really work is have either damage taken as cold/force a crit, or something hits you with cold, and crits. Or if there is a chance to be frozen.

Afaik you can't freeze yourself.
