Quick Question: scaling of weapons proc chance

I got a quick question to the better versed in the intricacies if GD mechanics: does the weapon proc chance scale with the % weapon damage on skills?

Example: Crescent Moon’s Moonglow has 15% on attack. Blizzard has 16% weapon damage. What’s the chance of one of the Blizzard’s shards to proc Moonglow? 15% or 15% x 16% = 2.4%?

15% on any and every player initiated hit.

Won’t work on quasi pets like storm totem or rune of hagaard though.

Thanks. By “any and every” do you mean it doesn’t have to have weapon damage in it? Will it proc, say, on Word of Pain or Curse of Frailty?

Yes yes and yes
