Malacoda is a guardian gargoyle and the Infernal Source’s 8th member of the Malebranche. It is found by entering the Scorpio portal on the Vestibule of Futility, the uppermost level of the Infernal Source. Malacoda is one of the thirteen Malebranche that must be freed during the Contract Claws mystery.
To free Malacoda of his contract, you must bring Frog Spawn to it. He will reward the player with Ramblings of a gargoyle, sequence 8 and gives the player a hint to be able to enter the Sagittarius portal.
Obtaining all twelve Ramblings of a gargoyle pages is required to complete the Contract Claws mystery.
