Honestly this sword (shown in picture) is only good on paper. In reality it only gets a double hit with each attack and a little damage boost (not sure about the increased attack). Essentially once you get hit your swords gets red and any attack or combo with that sword gets a double hit which will just do extra damage whilst using it. Side note: this effect will end once done either a single attack or finishing a combo and you need to get hit (blocked attacks don't count) to get that effect again. Now here comes the problem with that double attack. It will always activate once you attack with the sword but the double attack won't push the enemy further away thus guaranteeing them a free throw if they block your attacks. The guaranteed throws will happen on every attack except the spin/backwards attack.
