ZanVex is a legendary Runeword created by combining a Zan Rune of Ritual and a Vex Rune of Invocation.
How to Create ZanVex
You can create ZanVex by adding the magic Zan Rune of Ritual and the legendary Vex Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Zan - Cast an Ultimate Skill. (150)
Vex - Gain +3 to all Skills for 5 seconds. (400)
Overflow
When ZanVex overflows, you receive the Vex Rune's overflow effect (Increased Duration) 0.13 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
