MoniChac is a rare Runeword created by combining a Moni Rune of Ritual and a Chac Rune of Invocation.
How to Create MoniChac
You can create MoniChac by adding the magic Moni Rune of Ritual and the rare Chac Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Moni - Cast 2 Mobility or Macabre Skills. (100)
Chac - Invoke the Druid's Lightning Bolt, striking a nearby enemy. (20)
Overflow
When MoniChac overflows, you receive the Chac Rune's overflow effect (Increased Bolts Spawned) 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.
