Nameias Crimson Tome: Collective Ritual Casting System (5e)

These rituals require the spellcasters involved¸ to have access to the spell¸ either by having it written in a spellbook or a scroll. Collective rituals are often found inscribed in long-forgotten artifacts or murals of the past." - Rules for adding Collective Ritual Casting in your games - 22 Collective Ritual Spells Did you enjoy the product?
