Gilded Hydra

 is a gun that fires large bursts of piercing, bouncing bullets. Its magazine size is increased by 1 for each half heart the player is missing, and healing any missing health decreases magazine size.

Trivia

 * The decreasing health adding to the clip size is an allusion to the Lernaean Hydra of Greek mythology, a beast that would sprout two heads in the place of one that was severed.
 * The description is a reference to Revelation 2:1 in the Bible which says "these are the words of him who holds the seven stars in his right hand and walks among the seven golden lampstands."
 * The Synergy is a reference to Ennio Morricone's song "The Ecstasy of Gold" from the Western film "The Good, the Bad, and the Ugly."
