Vaal Storm Call has a base duration of 6s and hits every 0.25s = 24 hits per Cast. You can only stack 1 Charge.

Almost all skills which scale with duration won't increase the "hit-rate" when you reduce the skill duration via %reduced skill effect duration modifiers. BUT Vaal Storm Call is different because of this line: "Modifiers to the skill's duration will also affect the delay between these strikes"

So if we can get the Skill Effect Duration very low, we can hit 24 times in a very short timespan which increases the damage significantly.
Quick Note: "reduced skill effect duration" and "less skill effect duration" are completely different for Vaal Storm Calls calculation and we only want "reduced".


We stack reduced duration via:

Helm Enchant
Warped Timepiece https://www.poewiki.net/wiki/Warped_Timepiece
Dusk Ring (New Base introduced in Lake of Kalandra)
Passives in Tree (Window of Opportunity)


This results in a Vaal Storm Call Duration of 0.627s with 90% reduced Skill Effect Duration.
So we can effectively hit 38 Times with around 2 casts per second.

OH NO!
If you read Vaal Storm Call closely you will find those 2 lines being part of the Gem:

AND


This will essentially prevent the skill from recharging itself because 7s Soul Gain Prevention Duration with 90% reduced Duration is 0.7s which is still greater than 0.627s.

So how can we make Vaal Storm Call recharge itself?

Let me introduce Triumvirate Authority Unset Ring | https://www.poewiki.net/wiki/Triumvirate_Authority
This Ring drops from Atziri (3) / Uber Atziri (4) and has a random set of Vaal skill modifiers:


We need the 3 marked ones so a ring like this is mandatory:


When we socket our Vaal Storm Call in the Ring (1 Link) we benefit from:

"Socketed Vaal Skills have 30% reduced Soul Gain Prevention Duration"
will reduced our 0.7s Soul Gain Prevention Duration down to -1.188s (adjusted to Server-Ticks) = 0s. (120% reduced Vaal Soul Gain Prevention Duration in total)

"Socketed Vaal Skills deal 150% more Damage"
This functions like 3 50% more multipliers like other support Gems and makes it a 4 Link.

"Socketed Vaal Skills require 30% less Souls per Use"
This is important in the next chapter!


We now have a Vaal Storm Call which lasts 0.627s and hits 24 times and is able to self refill its one Charge. INFINITY!
