- The correct Ritual Spell Card in your hand.
- The corresponding Ritual Monster in your hand.
- Enough monsters in your hand, on your side of the field, or both, that satisfy the Ritual Monster's Level requirements, to be used as Tributes. (The exception being Advanced Ritual Art, where you must have enough Normal Monsters to satisfy the Level requirements of the Ritual Monster in the Deck)
- 1 free Monster Card Zone to Special Summon the Ritual Monster to.
Activating a Ritual Spell Card can tend to be somewhat demanding, and for that reason Ritual Spell Cards are arguably the least used Type of Spell Card. The only Ritual Spell Cards that have even seen minor use tend to be 'universal' types such as "Contract with the Abyss", which can summon any DARK Ritual Monster. However, the only Ritual Spell Card that has seen major play is "Advanced Ritual Art", due to it being able to use monsters from the Main Deck, thus being much less demanding than traditional Ritual Spell Cards. However, as this card fueled the then-powerful Demise OTK Deck, "Advanced Ritual Art" has since been Limited, thus mitigating the Ritual Monsters' usefulness.
