Call of the Void + Winterweave (Reverse Chill)

I play a Spark Inq with Call of the void and Winterweave to reverse the chill effect (with replica hotheaded) , i have noticed that something weird is goin on with the chill proc (most of the times doesnt proc properly) .

I have tested it a lot in maps and Blood Aqueduct , see monster life's drop under a certain % so chill can actually proc and doesnt , even if i one shot a mob still some times dont proc either which is weird ... (it procs from time to time but rly should have been up like all map with a juiced t16 maps i run and is up like 30% of the time )

If the support team have some spair time please take a look at it , i am pretty sure there is a proc bug 1000% .

Thanks for your time reading this :)
P.S. Sorry for my English

Can you explain what mechanism you use to inflict self-chill?
You should have something that hits you, to get chilled. Your belt reflect shocks back, but not chills.

Call of the void states - All Damage with Hits can Chill.
