Being the cheap piece of crap that I am I just now bought Vagrant Story...I'm stuck on the Wyvern boss (the second dragon type boss you fight)...I hit its tail with edged weapons and only do 3-4 damage, and I have a piercing spear with 23 dragon affinity and Prostasia cast on myself and still only do 3-4 to its head and body and all other body parts. Is the only way to beat it to reflect damage and heal? What's the deal!
