Hellhounds are one of the faster monsters that spawn during the third wave of the Pumpkin Moon event. They leap at the player to damage them and can pose a threat to casters or rangers due to their speed and ability to resist knockback. The best way to defeat them is to use a fast, high damage and knockback melee weapon such as Paladin's Hammer or Terra Blade, or fight them from an enclosed area using a Death Sickle. Despite its name, it doesn't spawn in the Underworld (hell) biome. They spawn in the 3rd-8th wave and 10th-13th wave of the Pumpkin Moon.
