Masamune blows because it is weak when auron is at high HP strong when he is low so most of the time (for me at least) he is at high hp and he does bad dmg... Caladbolg on the other hand does high when hp is high low when hp is low and has evade+counter mod which is useful... i would have to go with caladbolg... nice mods/ good hp-dmg / looks cool

never got onion knight cuz i refuse to dodge thunder but i like the way it looks
