When you told me to get to know the team, he told me all about it. Tiny, little, pill-sized bombs that are detonated by stomach acid. He also has an antidote that is meant to stop the casing from being dissolved or somehow neutralize the explosive component, but it's almost completely untested. He doesn't even know what sort of blast-radius it might have, but he implied it might be wide enough to level a city. Which is just...
Insane.
He didn't tell you about it? He's still trying to think of a more controlled way to test them.
