The Death Fog Grenade is a sinister and deadly weapon designed to unleash a poisonous fog that engulfs a large area. Crafted with expertise in alchemy and toxicology, this grenade is a glass vial containing a potent concoction capable of inflicting significant harm upon those unfortunate enough to be caught within its noxious grasp. The Death Fog Grenade is primarily used as a tactical tool to create a hazardous environment for enemies or to block off an area, limiting visibility and causing harm to those within. When thrown, the grenade shatters upon impact, releasing a dense fog of poisonous gas that quickly spreads and lingers.
To use the Death Fog Grenade, a character must take an action to throw it at a point up to 60 feet away. Upon impact, the glass vial shatters, and a heavy poisonous fog spreads in a 30-foot sphere, enveloping the area in a deadly haze. The grenade creates a dense fog that fills the designated area, spreading around corners. The fog persists for 5 minutes or until strong wind or similar means disperse it. Within the fog's area, visibility is heavily obscured, making it difficult for creatures to see or perceive their surroundings clearly.
When a creature enters the fog's area for the first time on a turn or starts its turn there, that creature must make a DC 18 Constitution saving throw. A creature that fails the saving throw takes 5d8 poison damage as the toxic fumes infiltrate their body, causing harm to their vital organs and systems. A creature that succeeds on the saving throw takes half damage, minimizing the effects of the poisonous gas. The poisonous fog of the Death Fog Grenade affects all creatures within its area, regardless of whether they hold their breath or possess any special abilities that allow them to survive without breathing. The toxic nature of the gas seeps through any defenses, making even the most resilient beings susceptible to its harmful effects.
The creation and acquisition of Death Fog Grenades typically involve skilled alchemists, poison experts, or black-market vendors with access to dangerous and forbidden substances. The ingredients and knowledge required to craft these grenades may be tightly regulated or illegal in many jurisdictions due to the immense harm they can cause. Obtaining such grenades may require involvement in illegal activities or connections to the underground market.
The Death Fog Grenade poses a significant risk to both enemies and allies. The dense fog can obscure vision, hindering both offensive and defensive capabilities. Additionally, the toxic nature of the fog can harm unintended targets, including allies or innocent bystanders. It is crucial to exercise caution and strategic planning when using such a hazardous weapon.
