The Gunsmith, Revised

Crafting and invention should define the artificer class, and each gunsmith’s Thunder Cannon should be a unique creation.  The Gunsmith, Revised realizes that philosophy.  Inside, you will find options to customize your Thunder Cannon as a pistol, rifle, or shotgun.  You will also find many powerful modifications to perform on the Thunder Cannon as you advance in artificer class levels.  I included any rules from the original Unearthed Arcana article that survived my playtesting so that, much like the revised ranger, the revised gunsmith fully replaces the original gunsmith specialty.
