Black Desert Mobile has launched the Dark Knight class. The Dark Knight wields a two-handed Kriegsmesser as well as black magic. Players who level up the Dark Knight character will receive special rewards, such as Ancient Gold Coin, High-Grade Crystal Chest, Good Black Stone Sack, and Shakatu’s Mystical Key, which can be used to strengthen equipment, upgrade the camp and grow the character’s Black Spirit.
The Tower of Trial has also been introduced into Black Desert Mobile. Players can send their level 45+ characters into the tower to complete quests and gain experience, allowing you to effectively level multiple characters simultaneously. In addition, auto-quest allows secondary characters to complete quests that your main has already finished, allowing for even more fluid alt-leveling.
