Witches and Priests can lead and participate in rituals. Those with the Incantation skill can also participate in rituals, but cannot lead them. However, Witches and Priests cannot conduct rituals together, and to attempt such will result in certain death.
Where there is no skill or spell that quite fits a spiritual or magical need, a ritual may be used to formulate a suitable solution instead.
There is no minimum requirement for participants in a Ritual as a single person is able to conduct one. However, scaling the power of the individual to the effect desired should be taken into consideration. Balancing relevant skills, spellcrafting and items will help to achieve a successful ritual. “Overcharging” rituals with too much power is only possible in extreme circumstances.
Example 1
A Priest is trying to Consecrate an area, but has found that it is slightly too tainted to do so alone with only this skill. Other Priests are currently occupied, so the Priest asks someone with Incantation, so that they can channel more of their power through a Ritual to attempt to cleanse the Evil from the area instead. The Priest Blesses the other participant for an extra boost. The ritual works, thanks to the extra time and skill put into the Ritual. If the area was larger, or even more corrupt than first imagined, then more people with Incantation or other Priests could join in to create a more powerful Ritual.
Example 2
A group of Witches want to close a portal to the Demonic Plane. After assessing the portal, they determine that several Greater Demons created this portal. This means that great power is required to close it again. The Witches recruit as many as possible, and try to go for higher level spell casters (e.g. Those with Greater Spellcrafting or Greater Pacts). They manage to get 4 Greater Spellcrafters and 2 Incantation users to conduct the Ritual. They also bring components that represent binding and closure, and some Greater Crystal. As an extra precaution, the Witches decide to use a Pact of the Coven to temporarily boost their combined power. This works excellently, as the right skills, abilities and resources were employed to deal with the scale of the problem.
Example 3
A group of three Priests wish to raise a ward around the portal that the Witches were able to close, so that the area is protected from breach again. Two of the Priests have skill Mastery (Purchased the Master skill set in their background), and the other is Advanced. Between them, they are easily able to establish a Greater Ward of Protection through the ritual which will make it significantly more difficult for a portal to break through again.
