Inferno Fork

The Inferno Fork is a hardmode magic weapon which is rarely dropped by Diabolists in the Dungeon. It fires a moderately slow moving fireball which will deal initial damage before exploding into a large, damaging cloud of fire which lasts for several seconds. If paired with the best magic enhancer, it can easily defeat any hardmode boss as it will deal great damage over time and has a large area of damage. Inferno Fork can outclass the Shadowbeam Staff since the shadowbeam staff needs preparation to help it bounce off walls (to maximize DPS and effectiveness), while the Inferno Fork will be just as effective in either in a prepared arena or a natural landscape. It also has more range than the shadowbeam staff, which is a huge factor.

Tips
the inferno fork can be used to battle huge amounts of enemies like the pirate invasion.thats because its flame shot stays for a while on the ground therefore damaging enemies that touch it and deals the on fire! debuff.
 * The Inferno Fork pairs extremely well with the Spectre Armor. The large area of the inferno will hit most enemies several times, with each hit providing healing from the armor set bonus. This is very effective against bosses such as The Destroyer or the Golem, as it will hit multiple parts of the boss.
