YaxLac is a rare Runeword created by combining a Yax Rune of Ritual and a Lac Rune of Invocation.
How to Create YaxLac

Challenging Shout
Overflow
YaxLac can not overflow because the amount of Offering you receive from the Yax Rune exactly fills the required Offering of the Lac Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
