This trick works best with Odd. Make sure you have the Defense upgrade. Block with B until a monster shoots a projectile at you. It will be reflected, but keep holding B. Start shooting, and when you are attacked, it will be blocked as if you had your shield up.
Try to get the LP upgrade first, then Double Attack, then Double Defense. After that, it is your choice.
While playing as any character with the Defense upgrade (except Aellita), it is easy to defeat monsters. When the monsters appear, hold your shield and watch their attack pattern. When the monster you want to hit is going to shoot you, release and press B. When the bullet hits, it will rebound. If the monster does not react, you may need to get closer. Continue doing this until the monsters die. Note: This does not work with any Boss.
You will fight the Scorpion three times. It goes Yumi, Odd, then Ulrich. Do about two to three circles of damage until the Scorpion runs away. Run away from the Scorpion. When he gets close, get in front of him. Strike while he is turning. When you do this, he will fall and you can get another few hits on him. When he gets up, run. Repeat this until you defeat him with Ulrich.
To defeat the Ulrich clone, you must have your sound on. Run around and stay away until you hear the clone shout. He will then be getting ready for a charge attack. This is when you should strike. You can get five hits in before he attacks. Run around until he shouts again. Repeat this until you defeat him.
