BP's Player Crafting Professions

One day, the fighter decides to take up the art of blacksmithing, leaving you in a rush to create a system for item crafting.  "Dang fighter, always wanting to 1-up the rest of the party," you think to yourself as you quickly search DMG for a good system.  At last! You have found it!  A balanced and enjoyable system to facilitate item crafting in your Dungeons and Dragons, 5th Edition campaign.  (For use with the upcoming "BP's Bountiful Booty" for a full material and recipe guide.) This edition of "Jobs" contains Blacksmithing, Harvesting, Tinkering, Alchemy, and Leatherworking and contains a simple progressive leveling system for each separate Job!
