Litho's Armory/The True Master Sword

The True Master Sword is a craftable post-Moon Lord broadsword. It can be considered an upgraded version of the Master Sword. Like it, after swinging it and holding down the left mouse button, the sword will charge up a Skyward Strike. When fully powered, it can be released to fire a projectile towards the mouse and deal massive damage. The sword also fires powerful sword beams per swing when the player is at full health.
