The Lingering Potion of Poison (0:11) is a throwable variant of potions that creates a cloud on impact, which applies a poison effect to any entities within its radius for 11 seconds. This concoction is crafted by adding Dragon's Breath to a regular Potion of Poison, allowing the toxic effect to linger in an area rather than affecting a single target, making it useful for controlling space in combat or setting traps for unsuspecting creatures.
