Gunblade

You are proficient in the use of the Gunblade, a strange and versatile weapon.

You gain proficiency in the Gunblade martial weapon.

You also obtain proficiency with the Tinker's Tools, which allow you to create infused cartridges for your Gunblade. To do so, during a long rest, you have to spend a total of 30GP worth of raw materials and perform a DC 12 Tinkering check. On a success you create 1d6 + your Wisdom modifier cartridges, while on a failure you will create only 1d4 cartridges.
The cartridges are infused with raw magical energy, that is then shaped in the desired form by you when using them with your Gunblade.

A Gunblade's cylinder can contain up to 6 infused cartridges. Reloading the cartridges of your Gunblade is an Action; at level 15, Reloading becomes a Bonus Action.
