If you use the creation spell to create gunpowder/black powder (assuming you have seen it), how long would it last? What material/materials would it fall under?

    \$\begingroup\$ I would really not recommend to do that. Introducing real-world sciences like physics or chemistry to a DnD campaign is a good way to break it. The rules of DnD were not designed to be balanced against real-world technology. You will end up with players turning low-level utility spells like create food and water into weapons of mass destruction. When you want to have a character in the campaign who is able to brew exploding concoctions, then you might want to look for a supplement rulebook with rules for alchemy. \$\endgroup\$

    \$\begingroup\$ Is "until it blows up" not the kind of answer you are looking for? 😯 \$\endgroup\$ Apr 18, 2021 at 23:04

1 Answer 1


12 hours

Creation says:

The Duration depends on the object's material. If the object is composed of multiple materials, use the shortest Duration.

  • Material - Duration:
  • Vegetable matter - 1 day
  • Stone/crystal - 12 hours
  • Precious metals - 1 hour
  • Gems - 10 minutes
  • Adamantine/Mithral - 1 minute

Gunpowder, or black powder,

consists of a fuel (charcoal), an oxidizer (saltpeter or niter), and a stabilizer (sulfur) to allow for a constant reaction.

  • Charcoal is vegetable matter (wood); 1 day
  • Saltpeter, aka potassium nitrate or nitre, is a mineral. As neither a precious metal nor a gem, it would last 12 hours
  • Sulfur is also a non-precious-metal, non-gem mineral; 12 hours

The shortest duration of these three is 12 hours, so by Creation's description, their mixture would also last 12 hours

    \$\begingroup\$ @Vikki — none, it is an (al)chemical product and as something not fitting into these groups can't be created, just as you can't create meat and bone that way. \$\endgroup\$
