Typical “fire and flame” explosives lack enough finesse to capture the imagination of most Gnomes. If they are going to blow something up, they are going to make it something worth seeing (and in the case of the Thunder Bomb, something worth hearing).
As an action, you can light this bomb and throw it at a point up to 60 feet away. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. On a failed save, a target takes 3d6 force damage and 3d6 thunder damage and is pushed 10 feet away from the center of the blast. On a successful save, the target takes half as much damage and isn’t pushed. Unsecured objects that are entirely within the area of effect are automatically pushed 10 feet away from the center of the blast.
The Thunder Bomb’s explosion erupts in a dramatic display of light. Every creature in a 40-foot-radius sphere centered on the point of the blast must succeed on a DC 15 Constitution Saving Throw or become blinded for 5 minutes.
The Thunder Bomb emits an ear-splitting boom. Every creature in a 60-foot-radius sphere centered on the point of the blast must succeed on a DC 15 Constitution Saving Throw or become deafened for 5 minutes.
You may complete your move action after throwing the bomb and before it detonates. After this item is used, it is destroyed.
