Ys 10: Nordics features some of the series's best and most fleshed-out character development. The character interactions in the Ys series have evolved thanks to the inclusion of building affinity with the party and crew members. Raising affinity with certain characters also unlocks special stories called 'Interludes'. The affinity mechanic will become available at the end of Chapter 2, when Adol gets named 'Adol the Red' and becomes Karja's Shield Brother. This guide will show you how to increase affinity with crew and party members in Ys 10: Nordics.
