Black Desert Online World Boss Karanda is located directly West Velia and Northeast of Calpheon. Karanda spawns 7 days a week. Boss timers can be found by clicking on the world boss image above.
Karanda Raid begins with focusing on Karanda herself. She will spawn and do three types of moves. One is a basic swipe with her wing and the other two are both aoe's that you must avoid. Karanda is more of a beginner boss as she is not to difficult to fight.
If you don't have the gear to fight Karanda you can always just get a couple hits off on her and then stand on the side. You can still get loot from her this way.
Killing Karanda has a chance of dropping a weapon box where you can choose between any Dandelion main awakening weapon. You get a Karanda aura which once you obtain 100 you will be able to turn them in for an Dandelion box. The other possible loot is something called a belongings of an adventurer. These are super rare and have a chance of dropping any accessory from the base version to tet!
