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

Challenging Shout
Overflow
PocLac can not overflow because the amount of Offering you receive from the Poc 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.
