Rules For Crafting Dynamite

Dynamite can be crafted by any creature that has proficiency with alchemist's supplies or tinker's tools, following the steps below.

Nitroglycerin
In order to craft dynamite, you must first acquire nitroglycerin. If you have proficiency with alchemist's supplies, you can craft your own nitroglycerin. Otherwise, you will need to purchase it.

Crafting Nitroglycerin Using Alchemist's Supplies
If you have proficiency in alchemist's supplies, you can create your own nitroglycerin. To do so, you must spend 4 hours working with your alchemist's supplies, and expend one of the currency amounts shown on the Nitroglycerin Crafting Table below, which represents the basic chemical supplies which are consumed by the process. At the end of the 4 hours, make an Intelligence (Alchemist's Supplies) check. The result of the check, and the amount of currency that you expended, determines the amount of nitroglycerin produced. You must decide how much currency to expend before you see the result of the ability check.

1 unit of nitroglycerin is sufficient to craft 1 stick of dynamite.

Buying Nitroglycerin
If you do not have proficiency with alchemist's supplies, you cannot craft nitroglycerin, and will need to buy it instead. See "Purchase Prices" below.

Crafting Dynamite
Once you have acquired nitroglycerin, you can use it produce dynamite, if you have proficiency in tinker's tools or alchemist's supplies.

To craft dynamite you must spend 1 hour working with the appropriate toolkit, and expend 1 unit of nitroglycerin. At the end of the hour, make an Intelligence check, using your proficiency in the appropriate toolkit. The result of the check determines the number of sticks of dynamite that you produce, using the Dynamite Crafting Table below.

Purchase Prices
Dynamite is not a common technology in this world, so you're not likely to find it in general stores. Alchemists and mining suppliers are the most likely vendors to sell nitroglycerin and/or completed dynamite.

The prices of dynamite and nitroglycerin vary widely, but in general, one unit of nitroglycerin is worth about 1gp, and a stick of dynamite is worth about 2gp.
