Starting February 6th, Blade & Soul players will be able to take part in the Prince of Darkness update that comes complete with a new 6-player Heroic Dungeon called the Brood Chamber. Players will also be able to play through "Blade & Soulmate", the annual event where "love is in the air".
Blade & Soulmate sees players completing the event's dungeons and a number of weekly raids and other event-specific quests. Doing so rewards the Lovestruck Coins that can be traded for a number of cosmetics and a "brand new costume that will set hearts aflutter".
Check out the details on the Blade & Soul site.
