Ciriatto is a guardian gargoyle and the Infernal Source’s 6th member of the Malebranche. It is found by entering the Virgo portal on the Vestibule of Futility, the uppermost level of the Infernal Source. Ciriatto is one of the thirteen Malebranche that must be freed during the Contract Claws mystery.
To free Ciriatto of his contract, you must feed it bacon. He will reward the player with Ramblings of a gargoyle, sequence 6 and gives the player a hint to blow a raspberry before being able to enter the Libra portal.
Obtaining all twelve Ramblings of a gargoyle pages is required to complete the Contract Claws mystery.
