NocWat is a rare Runeword created by combining a Noc Rune of Ritual and a Wat Rune of Invocation.

Overflow
NocWat can not overflow because the Wat Rune does not have an overflow effect.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
