Walkthrough

Sharess' Caress

Mamzell Amira can be encountered on the ground floor of Sharess' Caress by the front entrance. When asked what she has to offer, Amira mentions that a devil is in residence Raphael. At the bar, Korrilla can be met, informing the party that Raphael wishes to speak with them.

At the top floor Raphael can be found in a room labelled the Devil's Den. If Kith'rak Voss is alive, he is trying to make a deal with Raphael, but Raphael sends him away. He does, however, have a proposition for the party. Raphael is in possession of the Orphic Hammer which can break the cage that holds Orpheus. In return, he wants the  Crown of Karsus, which is being used to control the Elder Brain.

Raphael's proposal can be rejected or accepted. If rejected, he states that he will remain at Sharess' Caress for some time in case they change their mind. If accepted, he creates a Soul-Sworn Contract and the party instantly feels a pang of regret, starting  Escape the Deal.

Being forced to fulfill the deal

Raphael arrives in the Astral Prism.

If the party does not obtain the Orphic Hammer, either through making a deal with Raphael or stealing it from the House of Hope, then party's hand can be forced to fullfil Rapheal's deal. This occurs during  Confront the Elder Brain. After the initial confrontation, the Emperor steps in to protect the party from the Netherbrain and shelters them in the Astral Plane. During this time, the Emperor states that only an illithid can hope to take down the Netherbrain in its current form and that the illithid must consume the power of Prince Orpheus in order to succeed. As an illithid, the Emperor says he can do this, and asks the Netherstones be relinquished to him.

If choosing to say "I don't believe a word you just said." and then "I will never trust you.", then the Emperor becomes enraged and states that he has no other choice but to reassimilate into the Netherbrain. He leaves the party in the Astral Realm, with seemingly no options left to defeat the brain.

In this case, Raphael appears within the Astral Prism. Now the party must sign a contract for the Orphic Hammer in exchange for the Crown of Karsus. Refusing to sign turns the party members into mind flayers who are then assimilated into the Netherbrain, causing a Game Over.

After defeating the Netherbrain

Fulfilling the deal results in an additional cutscene after the credits roll. Raphael has already begun his conquest of the Hells, with many rulers already seeking to bargain with him. He threatens the prospect of turning to other realms once the hells are united, ending his speech with, "It won't be long before I come knocking at your door. Ta ta, for now."
