The Ritual

""You need to sacrifice yourself for the ritual...ESCAPE...Possible for only one?""

- —A Memo Written by Someone

The Ritual is an event in the finale of Cat in the Box. It is the only way for those who have entered the the Mansion to leave.

Procedure
The Ritual requires a red spider lily, ritual thread, a box of candles, the Sacred Chalice, and a human sacrifice. The sacrifice can be any part of the sacrifice's body. To begin the Ritual, the sacrifice must chant "I sacrifice for thee". The building will then begin to shake. The sacrifice should continue chanting until the shaking ceases. Only the sacrifice may leave the Mansion.

Outcomes
Failure to conduct the Ritual properly will result in tragedy. Divine is inferred to be the only case in the game in which the Ritual is conducted properly and leads to Girl's escape. In Epitaph, Girl sacrifices the Stranger's finger and is able to exit the Mansion, however she immediately runs off the cliff to the south and perishes. Girl may attempt to leave the Mansion immediately after entering, without conducting the Ritual at all, but the trail outside will become never ending, resulting in the Roam ending.

Sacrifices have a chance of eventually turning into a Monster.

Trivia

 * The Stranger (before being interrupted by Girl), as well as a document found in the Basement Sanctuary, implies that the Ritual requires blood from the sacrifice as well.
 * It is unknown if a sacrifice can conduct the Ritual more than once.
 * In his journal, the Cult Leader admits that he fabricated the Ritual out of various previously existing knowledge and does not know how it continues to work.
