Overflow
MoniRandom Rare or Legendary Rune can not overflow because the Random Rare or Legendary Rune 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.
