How do you capture cobalion in Pokemon black?

Answer 1

First, you have to go to Mistraliton cave. You can get to it by Surfing on the river in Route 6. Then, when you get in the cave, you have to keep going up the sets of stairs until you get to the third floor. You'll know you're on the third floor because it will tell you that you are in Guidance Chamber. You have yo talk to the old man and he will tell you a story. Then, you have to get through the very simple maze and you will see Cobalion. I would recommend that you use Timer Balls and that your Pokemon are at least level 35 (probably higher). Good luck in catching Cobalion!
