Yes, you need Cobalion to catch Virizion. You also need him to catch Terrakion in Victory Road. They are called something like the musket three but i forgot. You meet all of them at level 42.
To even get to Virizion, you have to catch Cobalion in Mistralton Cave. Virizion, is in Pinwheel Forest.
You first have to catch Cobalion so you can then catch Virizion. Because when you go to pinweel forest there are some stones covering the path to Virizion so I'd recommend getting Cobalion first. Then after that you can catch Terrakion.
Did you already catch Cobalion? it is impossible to catch virizion until you have caught cobalion. I'm not sure what happens if you faint it......so good luck
In Pokemon White, you can find virizion in a clearing in pinwheel forest that isn't accessable untill you catch Cobalion.
you first have to catch/defeat the legendary pokemon cobalion in mistralion cave you catch virizion in pinwheel forest
In Pinwheel Forest Rumination Field but, only after you catch Cobalion.
First you have to catch Cobalion in the Challengers cave and then you go to Pinwheel Forest. In the east there is a passage to a small field and Virizion is there.
No, you do not use Cobalion, Terrakion and Virizion in order to summon Keldeo.
Tornadus, Landorous, Reshiram, Virizion, Terrakion, Cobalion, Kyurem, and Victini .
You can catch virizion, terrakion, cobalion, zeckrom, thundurus, landurus,kyurem, and celihidron
You catch it in the Pinwheel Forest but only after you have caught Cobalion, which is at Mistralton cave ok, but what if you already beat it. then what do you do?
Well first you have to have terrakion and cobalion and think you have to have them in you're party and then go to pinwheel forest
