AhuLum is a legendary Runeword created by combining a Ahu Rune of Ritual and a Lum Rune of Invocation.
How to Create AhuLum
You can create AhuLum by adding the legendary Ahu Rune of Ritual and the magic Lum Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Ahu - Lucky Hit: Up to a [100|%|] chance against Injured enemies. (25)
Lum - Restore 2.5 Primary Resource. (5)
Overflow
When AhuLum 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.
