Player wants to be able to improvise bombs, but obviously there's not much here in the rules - just that it's a "build test." I'm trying to figure out how to balance it so that it's not just easier and cheaper to get via the black market. Seems like she'd need supplies, and just figuring out the cost of the supplies and whether they'd be easily available is throwing me off.

Anyone have any experience with this?

An ANFO bomb would just be a commercial explosive.

If she's trying to make something like a ammonium nitrate + fuel fertilizer bomb, you need to figure out (or simply handwave) the tnt equivalency.  For the sake of easy math, I'd probably rule that it's half as effective as commercial grade, so rating 5 per 2 kg.  I'd also seriously consider various modifiers from the B/R table on page 146, since it's tricky to create great working conditions when you're dealing with a few hundred pounds of fertilizer and diesel fuel.  Especially if she has a low lifestyle, 1BR apartment.

Look into Arsenal. You'll be pleasantly surprised.

You weren't kidding, Lysanderz - everything is there. Fantastic. Seems real easy to adapt to 5E, too. Thank you!

I don't know how the costs convert, but the rules will do until the next gear book comes out.

Your mileage may vary

just a quick glance at gear, but it seems things in 5e are between 5-15% more expensive on the whole, while damage is up 10-20% as well....

More research is needed to comfirm that though, so I am probably off by a fair margin.
