Hellfire Shotgun

The Hellfire Shotgun is a craftable Hardmode gun crafted from 1 Onyx Blaster, 2 Ectoplasm, 6 Dusk Shards, and 12 Chlorophyte Bars at a Mythril or Orichalcum Anvil. It shoots a tight spread of life-stealing bullets that pass through blocks. After 20 shots it triggers Death Blossom, causing the next three attacks to release rings of enemy- and wall-piercing projectiles in addition to the usual shots.

Trivia

 * The Sanguine enchantment's lifesteal stacks with this weapon's, making for a very strong synergy.
