The Alchemical Flask is a craftable Hardmode accessory that inflicts the Plague debuff for 2, 4 or 6 seconds to enemies you attack. It also removes the blindness effect and reduces the damage over time effect by 50% from the Plague debuff, and causes all projectiles to spawn Plague Seekers when they hit an enemy.

Plague seekers deal 25% damage of the attack that spawned them, capped at 30 damage.
