AhuTec is a legendary Runeword created by combining a Ahu Rune of Ritual and a Tec Rune of Invocation.
How to Create AhuTec
You can create AhuTec by adding the legendary Ahu Rune of Ritual and the magic Tec 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)
Tec - Evoke the Barbarian's Earthquake, dealing damage to enemies within. (100)
Overflow
AhuTec can not overflow because the amount of Offering you receive from the Ahu Rune exactly fills the required Offering of the Tec Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
