Libicocco is a guardian gargoyle and the Infernal Source’s 2nd member of the Malebranche. It is found by entering the Taurus portal on The Harrowing, the middle level of the Infernal Source. Libicocco is one of the thirteen Malebranche that must be freed during the Contract Claws mystery.
To free Libicocco of his contract, you must use the angry emote once, then step through the portal. Use the angry emote again.
He will reward the player with Ramblings of a gargoyle, Sequence 2 and gives the player a hint to be able to enter the Gemini portal.
Obtaining all twelve Ramblings of a gargoyle pages is required to complete the Contract Claws mystery.
