The Master Sword? Not really. It has the highest attack power out of any weapon in the game. with both skills unlocked, it's attack power is boosted to 900. Plus it unlocks the attack power boost skill, "Legendary" for everyone else. I got a Toon Link with a 5 star tier 4 weapon with the attack power of 840. Every other 5 star tier 4 weapons base power is 750.
