Gunner

A half-orc raises his blunderbuss, and sends a kobold flying as his mechanical unicorn charges in, impaling the poor creature on it's horn.  It then opens up into a set of armor as a mechanical fox rushes up and jumps towards his master, transforming into a Greatsword as his master uses him to finish off the kobold.

A Drow female aims her flaregun and lets loose an acid bolt, splashing in an area before raising a hand to the sky, and calling down a storm of ice to smite her foes.  She sees a group of armored soldiers, and reloads with lightning rounds, and unloads into the area, electrocuting them where they stand.

A Human male sees a dragon rampaging through a city, lies down on a hill and takes aim.  He looks through his scope and fires directly into the beast's eye, causing the creature to breathe fire in his direction, but he rolls out of the way, loads another round, and this time connects with the beast's skull, shattering it, and causing the might dragon to fall.

This is a new take on a class, where each archetype is completely unique from the other 2, allowing multiple to join a party, while fulfilling different roles!

The guns that they use are included within the pdf, the Marksman seems to be a little strong, but since it needs to be in a prone position in order to unlock it full potential, it seems like a self balancing act, (DM may alter these type effects as he sees fit, whether all but barrel need prone to activate, or just bipod)

if you have any questions on what is meant, send me a message, and also, PLEASE leave me some feedback when playtesting, it will allow me to either fix issues, or get better as I progress.  Thank you so much for taking the time to look at this I made.

Machinist - Pet based tank class

Artillery - AOE psuedo caster, but with limitations on abilities based on spells

Marksmen - Super single target damage, at cost of becoming super vulnerable if spotted
