IgniLum is a legendary Runeword created by combining a Igni Rune of Ritual and a Lum Rune of Invocation.
How to Create IgniLum
You can create IgniLum by adding the legendary Igni Rune of Ritual and the magic Lum 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)
Lum - Restore 2.5 Primary Resource. (5)
Overflow
When IgniLum overflows, you receive the Lum Rune's overflow effect (Increased Resource Restored) 4 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
