CirYom is a legendary Runeword created by combining a Cir Rune of Ritual and a Yom Rune of Invocation.

Overflow
CirYom can not overflow because the Yom 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.
