AhuMet is a legendary Runeword created by combining a Ahu Rune of Ritual and a Met Rune of Invocation.
How to Create AhuMet
You can create AhuMet by adding the legendary Ahu Rune of Ritual and the magic Met 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. (10)
Met - You leave the Necromancer's Desecrated Ground behind you for 3 seconds, dealing damage to enemies within. (100)
Overflow
AhuMet can not overflow because the amount of Offering you receive from the Ahu Rune exactly fills the required Offering of the Met Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
