Skill Gem Combination?

Hello. I want to ask you.
Will Endurance charge on Melee Stun work with Herald of Ice?
Thank you.

Is Herald of Ice a melee attack?

Well.. no but Herald of Ice is ADDED TO YOUR ATTACKS..thats why im asking..

Unless you haven't figured it out by now I'll tell you that it will not work.
Endurance charge on melee stun only supports your active melee skill, ie groundslam, doublestrike etc.
Not heralds. Not ranged skill. Not spells. And so on.

An easy way to see if support gems work with the skill you want to use. Is to test it and see if the skill icon changes and get supported by the gem.

I did as you said and i just checked some combos. Decided to link with Cold to Fire. Thank you.
