YaxChac is a rare Runeword created by combining a Yax Rune of Ritual and a Chac Rune of Invocation.
How to Create YaxChac
You can create YaxChac by adding the magic Yax Rune of Ritual and the rare Chac Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Yax - Drink a Healing Potion. (200)
Chac - Invoke the Druid's Lightning Bolt, striking a nearby enemy. (20)
Overflow
When YaxChac overflows, you receive the Chac Rune's overflow effect (Increased Bolts Spawned) 9 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
