Pack of Revisibility Bombs

Alter: A pack of revisibility bombs typically includes 1d3+3 fist sized bombs when found. You can use an action to throw a bomb at a point you can see within 60 feet of you. The bomb explodes at the point where it impacts, destroying the bomb and releasing a dispelling vapor in a cloud around it. When the bomb explodes, each creature within 30 feet of it must make a DC 20 Dexterity saving throw. On a failed save, the creature becomes visible if it isn't already, and can't become invisible for 1 minute. Objects within the area that aren't being worn or carried automatically become visible if they're invisible and cant' become invisible for 1 minute.
