XolChac - Forbidden Cloudburst

XolChac is a legendary Runeword created by combining a Xol Rune of Ritual and a Chac Rune of Invocation.

How to Create XolChac

You can create XolChac by adding the legendary Xol Rune of Ritual and the rare Chac Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.

Xol - Invoke a Skill from another Class. (150)

Chac - Invoke the Druid's Lightning Bolt, striking a nearby enemy. (20)

Overflow

When XolChac overflows, you receive the Chac Rune's overflow effect (Increased Bolts Spawned) 6.5 times.

Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
