Acid Grenade

This small explosive is the invention of the artificer Cash Vexx. Using his mechanical ingenuity and alchemical prowess, he developed a weapon that explodes when it experiences impact such as being thrown, dropped, or hit.

The explosion releases acid in a 5-foot radius and each creature in that area must succeed a DEX saving throw with a DC equal to the spell save of the artificer who built the device. Each creature takes 1d4 acid damage on a failed save, or half as much on a successful one. 

The device can be improved by an artificer of 5th, 11th, or 17th level, increasing the damage dealt by 1d4 each improvement with its last possible upgrade at 17th level. 

This device must be crafted by someone who understands how to make it. An artificer can spend 8 consecutive hours studying the device to gain this knowledge, and a creature of any other class will require 16 hours over a 24 hour period to accomplish the task. The components needed include 1/4 pound of sulfur powder, a small vile of adder venom, a small leather pouch, and a short string. It takes an artificer 4 hours to make a single grenade, and a creature of any other class who has the knowledge of the device will need 8 hours to craft one.
