NeoLum is a rare Runeword created by combining a Neo Rune of Ritual and a Lum Rune of Invocation.
How to Create NeoLum
You can create NeoLum by adding the rare Neo Rune of Ritual and the magic Lum Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Neo - Deal damage after not taking any within 5 seconds.
(Resets if Invulnerable.) (300)
Lum - Restore 1 Primary Resource. (5)
Overflow
When NeoLum overflows, you receive the Lum Rune's overflow effect (Increased Resource Restored) 59 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
