Inferno Fork

Diabolist drop and lingering fireball blast

Dropped by the Diabolist in the post-Plantera Dungeon, typically inhabiting areas with tiled wall patterns. Casting the fork launches a high-speed bolt of mystical fire that travels forward and erupts into a lingering explosion sphere on impact with tiles or enemies. The weapon inflicts 70 base magic damage with 5 knockback for 18 mana per cast at a use time of 30.

Chokepoint area denial and Hellfire infliction

The resulting explosion sphere persists in place for roughly 2 seconds, inflicting continuous multi-hit damage and the Hellfire debuff on any monsters caught within its radius. This lingering zone makes the fork well suited for sealing Dungeon doorways or defending spawn lanes in the Old One's Army. Pairing it with Spectre Mask produces a cascade of homing spirit bolts. The best modifier is Mythical.

Trivia

• The Diabolist uses a similar lingering fire explosion attack against the player in the Dungeon.
• The lingering flame sphere created upon impact passes through solid blocks, damaging enemies on the opposite side.
