Blood and Wine includes over 90 new quests and 40 new points of interest. It also introduces a dynamic system, where interacting with an area's main POI affects adjacent points -- for example, killing enemies in their main hideout lowers their numbers in surrounding camps. Additionally, there will be 14,000 new lines of dialogue, which is 8,000 more than the previous expansion.
New gear and monsters include over 30 new weapons, 100 individual pieces of armor, and more than 20 new monsters. No specifics were announced.
12 new mutations were detailed, however, and players will be able to unlock them in New Game Plus. The mutations include one that causes enemies to freeze and die instantly when knocked by Aard, one that makes enemies to explode when they're killed with a sign's critical hit, and another that heals and grants you damage immunity when you lose all of your health.
Other additions include the New Game Plus maximum level increasing to 100, a new "Skellige" Gwent deck, and a redesigned user interface. Players will also be able to change the color of their gear with armor dyes that can be obtained through merchants, recipes or loot. However, these can only be acquired in Toussaint.
Unfortunately, a release date has still not been announced for Blood and Wine. Polish gaming site GRYOnline posted a listing that said it would be released on June 7, but that has not been confirmed.
