Conjure Object

Conjured objects are not suitable as material components for spells. While they can be eaten, when your concentration is broken the hunger returns. This also ends the effects of poisons or medicines once they disappear. Conjured objects are at the same basic temperature as their surroundings and must be solids at that temperature. If you wish to conjure a liquid, gas, or energy you'll want to look into other spells. However, you can conjure silver and then melt it into a liquid or conjure wood and burn it.
You must be familiar with the object in your day-to-day life such that you can envision it clearly. If you want a key that will open the door in front of you, you'll need to know exactly what it looks like. Similarly, you cannot conjure substances that a person of the setting would be unfamiliar with. If gunpowder doesn't exist in your setting, it cannot be conjured. You cannot conjure thermite, C4, machine guns, gasoline engines, or the like.
Also, you must conjure the object so that you are touching it and so that no one but you can see it, such as pulling it out from behind your back or from under a cape or in a room that no one else can see into.
