this Rock seems to be different from the other rocks around it, you feel as if it is staring at you Smoldering   as you hold this in battle you take 1d4 Fire damage every turn if you don't throw it when you throw it a very familiar sound plays a boom causing the thing it hit to be knocked back 5 feet and knocked Prone and it deals 1d8 bludgeoning + Strength Modifier  

Notes: Damage: Fire, Damage
