Terraria Overhaul/Boomstick

The Boomstick is a gun occasionally found in Jungle Shrines, Jungle Crates, and Ivy Chests located at the base of a Living Mahogany Tree in the Underground Jungle. It is a double-barrelled shotgun which can fire a eight-shot spread from each barrel, consuming only one bullet per barrel. The Boomstick has a Hardmode upgrade, the Shotgun.
