MoniTec is a magic Runeword created by combining a Moni Rune of Ritual and a Tec Rune of Invocation.
How to Create MoniTec
You can create MoniTec by adding the magic Moni Rune of Ritual and the magic Tec Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Moni - Cast a Skill after moving.
(Cooldown: 0.25 seconds) (25)
Tec - Invoke the Barbarian's Earthquake, dealing damage to enemies within. (100)
Overflow
MoniTec can not overflow because the amount of Offering you receive from the Moni 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.
