Question about Urgot and on hit items.

Basically does His W (Purge) Proc any of these items On hit effects? And if so does the Effect drain mana each shot from your W?
Also will this one, cause
&
to proc twice?

Hey!
Been playing Urgot recently and can confirm a few items that his W will proc:
This is why this item is recommended on him. W procs repeatedly and makes it super easy to stick to someone and get your full damage off.
Tested the other night and yes it gets stacks off of your W really quickly. Not positive though if it's passive kicks in and will proc twice during the Purge.
This was a nice surprise. W will stack and proc the discharge very quickly.
W applies on hit effects, so yes it will proc multiple times on a target.
Shreds armor almost instantly while giving movement speed.
Not positive here but pretty sure that W was shooting off multiple projectiles while active. I thought I even saw multiple shotgun blasts when those were proc'd but I need to test more.
Final notes: Urgot's W applies all on-hit effects and should in theory work with any on-hit item in the game. This is why Fervor is a good keystone for him because your W hits 3 times per second for 4 seconds which allows you to fully stack Fervor very quickly. Once the pre-season drops, fervor with stack infinitely, so in theory, one W will stack Fervor to 12.
