Vaal Storm Call is a Vaal spell that sets a marker at a location. While the marker remains, lightning strikes random enemies near it, dealing damage to them. After a short duration, a large bolt of lightning strikes the marker, dealing damage around it. When this happens, it will also set off the lightning at any other markers from this skill.

Skill functions and interactions

Unlike the Storm Herald Nemesis Affix found on monsters, the lightning strikes made by Vaal Storm Call will always hit a random target and never miss.

It is speculated that the lightning strikes follow the same rules as the ones from Herald of ThunderHerald of ThunderSpell, AoE, Duration, Lightning, Herald

Skill Interactions

• Area of Effect: Affects both the area in which periodic lightning strikes occur and the area of the final bolt.

• Area of Effect damage: Affects the damage of both the periodic lightning strikes and the final bolt.

• Critical Strike: Because Vaal Storm Call is only a single spell, its critical strike chance is only rolled once. If it crits, every lightning strike including the final bolt will be a critical strike. If it doesn't crit, none of them will be.^{[citation needed]}

• Cast Speed: Affects the speed of the initial Vaal Storm Call cast, but does not affect the skill's periodic lightning strikes.

• Skill Effect Duration: Modifiers to the skill's duration will also affect the delay between the lightning strikes. Therefore, Less Duration Support increases Vaal Storm Call's DPS whilst also lowering the Soul Gain Prevention timer.
