Apart from regular party members, w Pillars of Eternity 2 Deadfire also features sidekicks. They're just as powerful and are also visible on the team bar, but you cannot form bonds, or romance with them. These are just fatter characters, which don't have any unique missions and don't participate in the relations system.
The following page contains locations of all the sidekicks in the game, along with their classes:
Konstanten is in the Queen's Berth (M11) in Neketaka, in the second floor Wild Mare (M19) to be more exact. You can pay him to be able to enjoy a relaxing bath, and if you talk to him for a longer while, Konstanten will ask to join your team.
Character classes available for Konstanten:
- Howler (Barbarian + Chanter)
Ydwin is also staying in Neketaka, in the Sacred Stair (M14). Ydwin can be found in the building highlighted above (second floor). He will agree to join you after a brief conversation.
Character classes available for Ydwin:
- Mindstalker (Cipher + Rogue)
Fassina is the last sidekick found in Neketaka - this time you have to go to Periki's Overlook (M15) and head to The Dark Cupboard (the entrance to that location is marked in the picture above). However, you need to complete The Archmage's Vault quest first before you join Fassina to your party - that quest requires you to visit Arkemyr's Manor. More information can be found on the page dedicated to The Archmage's Vault quest found in the chapter dedicated to Neketaka island.
speak with Fassina once the quest is completed - the Wizard will gladly join your party.
Classes available to Fassina:
- Loremaster (Wizard + Chanter)
- Sorceror (Wizard + Druid)
If you want Rekke to join, you have to get ready for a long sea excursion. Take the ship and go to the world map.
Take a look at the above screen. We've highlighted Rekke's estimated location in red. Some abandoned barrels and crates that you've certainly ran into before. This time, though, a paragraph scene will be triggered after reaching them. You will learn that there's a person there. Taking her on board will begin a conversation with Rekke, and you will be able to join him to the team.
For clarity, we've also highlighted the Neketaka Island with yellow. You can also use the exact coordinates, which are as follows: 15° 9' S, 69° 7' E. You can look them up in the top-right corner, right above the Known Locations button.
Character classes available for Rekke:
- Brawler (Fighter + Monk)
- Brute (Fighter + Barbarian)
