The mouse smiled brightly: it outfoxed the cat! Then down came the claw and that, love, was that.
Spoiler warning: The following content contains unhidden spoilers. Read at your own risk.
Raphael will introduce himself to the player one night not long after the fall of the Nautiloid. He appears disguised as a Human with an enigmatic personality, and the player can act diplomatically or hostile about his presence.
Regardless of the player's opinion, he will teleport the party to the House of Hope where he will reveal himself as a Cambion. The devil will then offer them to lavishly partake on the supper he prepared, speaking in riddles as if he is aware of the player's condition.
Raphael will offer the player a deal: to remove the Tadpole in exchange for the player's soul. He warns them that when their luck and time runs out, he'll appear one last time.
(See Notes below for the list of triggers for this encounter.)
Korrilla
If the player is captured by Gut, a Warlock named Korrilla will stab the Goblin as she's about to kill the player, killing her instantly. She will then free the player and reveal Raphael sent her. She will then tell the player to watch their back, as Raphael is not always going to be around to save them.
Regardless of if you have interacted with Korrilla before, she can briefly be found at the Campsite, during the 'Celebrate at Camp' stage of the Save the RefugeesQuest. Shortly after the party starts, Korrilla appears to teleport into the northern part of the camp and can briefly be found sneaking around, towards where Gale is camped, before disappearing.
If the player is spotted getting too close, she will disappear, with the player's character making a remark about a "bizarre" smell of sulphur. If the player can get close enough without being detected, it is possible to pickpocket her for some common items and a small amount of gold, or trigger two lines of dialogue before she disappears.
Act Two
Spoiler warning: The following content contains unhidden spoilers. Read at your own risk.
If Mol was saved, Raphael will first appear at Last Light Inn playing lanceboard with her. If Astarion is in the party, Raphael will offer him a deal for information about his scar.
Mol can be spoken to after Raphael disappears, and will tell the party that she is considering making a deal with him.
He will later appear outside the Grand Mausoleum, practising his monologue. Here he will warn the party of a creature within the Mausoleum, and ask for it to be killed. Killing the creature also acts as payment for Astarion's deal.
If Astarion made a deal, he will appear at camp after beating the creature to fulfil his side of the bargin.
Korrilla
Korrilla can be briefly spotted and spoken to outside the Rethwin Masons' Guild in the Shadow-Cursed Lands, still keeping an eye on the party.
Act Three
Spoiler warning: The following content contains unhidden spoilers. Read at your own risk.
Raphael will be in the Devil's Den at Sharess' Caress speaking to Voss, who wishes to make a deal with him in exchange for the Orphic Hammer. He is uninterested in anything Voss has to offer, but will instead offer it to the party in exchange for the Crown of Karsus. Raphael wants to unite the hells using the crown, and rule over them. The party can take this deal, or attempt to steal the Hammer from Raphael's House of Hope.
The party can also just visit (or loot everything but the hammer) from Raphael's house. Here they will discover he is keeping Korrilla's sister, Hope, captive, and that he prefers to have sex with an incubus who looks like a younger version of himself, Haarlep.
If the party takes the deal, Raphael will have a short cutscene at the end of the story, where he reveals his ambitions to take his rule further than just the hells.
If the party instead steals the hammer from his house, Raphael will confront them as they are trying to leave, and must be killed.
Korrilla
Korrilla will appear at the bar of Sharess' Caress and will try and convince the party to take Raphael's deal.
