Hmm, I like this idea. Maybe tinkers can create a flour bomb out of some gears, an explosion potion and a sack of flour.
It acts like an explosion potion, so you dclick it, throw it, and it explodes for minor damage and makes things around it visible (since they're covered in powder now)

Good idea Eru, I think that would be a great addition. It would fizzle recall just like an explosion potion and also reveal. It would need a shorter countdown to be effective, or it would need to explode when it hits the ground. Also the cost of these bombs should match the resource cost of invis pots, or be higher, so invis pots don't get "phased out" if the new bombs turn out to be super effective.
I hope you make it happen Eru, this would be great.
