Kingkong Tesseiga?

This is the secret about a sword "kingkong Tesseiga"
One of the ability is "+20%" range attack??? Why would a sword give such trash ability?
The usage of this sword is to pvp, "Mainly"

A short answer to what this sword do is:
When use this sword.
Skill attack will be melee attack(use your melee atk to attack)
Normal attack will be RANGE attack(use the range attack u have)
:D
Think about pvp, and u will know why they design the weapon.
Remember melee pet can only block melee attack :)
