There aren't many NPC side quests in Deathbound, at least not to our knowledge. But this Soulslike does have one pretty early on in the second area of the game, but it's relatively easy to miss. While Rafaili does speak to you as you walk by where he's staying in the Lower Districts, you don't have to stop and talk to him (he'll only talk to Iulia anyway), and he only goes into the specifics of what he wants if you talk to him multiple times.
