Impaler

The Impaler is a craftable Hardmode repeater and an upgrade to the Stake Launcher. It rapidly fires fire stakes with a 33.33% chance to fire an exploding stake instead. Exploding stakes pierce 7 enemies and cause explosions on hit, while fire stakes pierce 9 enemies and inflict the On Fire! debuff. Instead of having bonus damage against Vampires like the Stake Launcher, the Impaler will instantly kill Vampires.
