Medusa Head

The Medusa Head is a chargeable Magic Weapon dropped by Medusa in Marble Caves. This weapon can be charged for up to 3 seconds to deal additional damage, consuming 4 mana per second to a maximum cost of 12. When full charge is achieved, the weapon will automatically discharge, hitting all enemies across the entire screen. It cannot hit targets with solid blocks between themselves and the user.

Tips

 * Medusa's head is very powerful against enemies with multiple segments, as a full charge can deal over 100 damage to each individual segment which can instantly kill most worm enemies and heavily damage large parts from the Eater of Worlds. It is also very efficient for defeating Brain of Cthulhu's creepers.
 * The center point of the Medusa Head's effect is not the raised head, but rather the front of your torso, just below your face. As a result, enemies that appear to be targetable may not be affected. In addition, there appears to be an exactly 2 block minimum space requirement for the attack to "pass through" and hit a target, causing walls in narrow vertical tunnels to block attacks going straight up or down due to the start point being off center from the tunnel.

Trivia

 * Medusa's head originates from the Greek legend of Perseus, who was commanded by King Polydectes to kill Medusa and return with her head, and later on he used it to save Andromeda by turning Ketos into stone.
 * When used the snakes on Medusa's head will stick out their tongues, and her eyes will flash.
 * This item may be a reference to the weapon Kratos uses in the God of War series.
