Version 4 of Icewind Dale NPCs adds fifteen lovetalks to each romanceable character, sixty in total. It means that if you're say, playing a female character and romancing Korin and Holvir, each of them will have two lovetalks each chapter, two more lovetalks for the Heart of Winter, and one more - for the Tales of the Luremaster. Same for a male character with Nella and Teri. Enjoy!
