The Plagued Fuel Pack is a Hardmode accessory dropped by Plaguebringers. While equipped, rogue damage and projectile velocity are passively increased by 5% and 15% respectively. The player's stealth also generates 10% faster.

Pressing the Booster Dash key causes the player to dash diagonally upwards in the player's direction at the cost of 25% of the player's stealth, leaving a trail of damaging clouds that inflict the Plague debuff. The dash has a 3 second cooldown before being usable again.
