The first true firearm and the successor of the fire lance. It is the oldest type of small arms as well as the most mechanically simplistic form of metal barrel firearms. Unlike matchlock firearms it requires direct manual external ignition through a touch hole without any form of firing mechanism. It may also be considered a forerunner of the handgun. The hand cannon was widely used in China from the 13th century onward and later throughout Eurasia in the 14th century. In 15th century Europe, the hand cannon evolved to become the matchlock arquebus, which became the first firearm to have a trigger.

It’s up to you to decide whether a character has proficiency with a firearm. Characters in most D&D worlds wouldn’t have such proficiency. During their downtime, characters can use the training rules in the Player’s Handbook to acquire proficiency, assuming that they have enough ammunition to keep the weapons working while mastering their use.
