The Acid Grenade is a menacing weapon developed in the Vache Kingdom, known for its destructive capabilities. This vile invention is primarily utilized by bounty hunters, assassins, and those seeking to unleash devastation upon their enemies. The grenade is a glass vial filled with a highly corrosive acid, designed to inflict significant damage upon impact. The Acid Grenade is a potent offensive tool used to dissolve armor, weapons, and living flesh. It is particularly effective against heavily armored foes or those seeking cover. When thrown, the grenade shatters upon impact, releasing the acid in a volatile and destructive manner.

To use the Acid Grenade, a character must take an action to throw it at a point up to 60 feet away. Upon impact, the grenade explodes, releasing a spray of corrosive acid within a 20-foot radius. Each creature within the 20-foot radius must make a DC 17 Dexterity saving throw. A creature that fails the saving throw takes 10d8 acid damage. The acid sears through armor, flesh, and materials, causing ongoing damage until it is neutralized or washed off. Additionally, the acid has a chance to eat away at the target's equipment, potentially rendering it damaged or destroyed. A creature that succeeds on the saving throw takes half damage, meaning it takes 5d8 acid damage. The creature manages to dodge most of the corrosive spray, minimizing the harm suffered.

The creation and acquisition of Acid Grenades is typically restricted to individuals with knowledge of alchemy or access to skilled artisans. Due to the highly dangerous nature of these grenades, their production may be regulated or illegal in certain regions. Acquiring or crafting Acid Grenades often involves obtaining rare and dangerous ingredients, such as specialized acids and glass vials capable of containing the corrosive substance.

The possession, creation, and use of Acid Grenades may be subject to legal restrictions and penalties depending on the laws and regulations of the game world. Some jurisdictions may consider them prohibited weapons due to their destructive capabilities and potential for indiscriminate damage.
