IgniXal is a legendary Runeword created by combining a Igni Rune of Ritual and a Xal Rune of Invocation.
How to Create IgniXal
You can create IgniXal by adding the legendary Igni Rune of Ritual and the rare Xal Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Igni - Stores offering every 0.3 seconds. Cast a non-Basic Skill to gain the stored offering. (Up to 500 Offering). (25)
Xal - Gain 20% Maximum Life for 6 seconds. (300)
Overflow
IgniXal can not overflow because the amount of Offering you receive from the Igni Rune exactly fills the required Offering of the Xal Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
