If you want a Uragaan Ruby you need to do Uragaa+. When you do that you need to breake his jaw and cut his tail. Then cap Uragaan. You got the monst chance then. Believe my it works. Maybe not the first time but keep trying. My friend chiron (The Licht Hunter) was having trubble with Uragaan Ruby to. he tryd and tryd but no Ruby! At the end finely he got 2 Ruby's.
