Death Potion
It has many ways to ---- a person. If someone makes contact with the liquid, it melts them just like acid. Throw the potion at the ground, it causes an explosion. If you try drinking its contents, you get poisoned. Even breathing its fumes will cause the lungs to shut down and it's radioactive when exposed in certain conditions. 
This potion can be used as a weapon, just be careful when handling it...
