YulMot is a legendary Runeword created by combining a Yul Rune of Ritual and a Mot Rune of Invocation.

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