Beating Vaylin in 5 minutes ( does not matter what class you are)
1. Get some heal pots from fleet for emergency before starting fight
2. When fight starts either hit Vaylin with a range strike or melee just once. Then run around the stairs avoid the purple circle. When the heal circles appear if you are under half hitpoints use the circle to heal. If you are above half hps, then train Vaylin into circle. The circle will do massive damage to Vaylin. Once Vaylin is in circle she will loose about 1/4 total hps and be stunned. Use Force power and run away to make her run toward you. Use the next healing circle on yourself. You need to put Vaylin in 4 circles and the circles will kill her.
