WARP Character Classes

Skip the chatter.
Like in most role-playing, every player character belongs to at least one character class - some are multiclassed, which is its own brand of complication. Many non-player characters, especially long-term ones, also belong to a class.
There's one main difference between WARP and D&D's character class systems: in WARP, any character can be classified; in D&D, there are only adventurer classes.
Sure, some class members don't go adventuring - guards (fighters) who stay at one royal treasury, priests who work the temple, thieves who (quietly) work the marketplace and never get caught, and so on - but no one really knows, in D&D, what class to put traders, farmers, full-time makers of things, and so on, in.
WARP has a solution. If your DM approves, this can even be used in D&D campaigns, but make sure the rules are understood by everyone involved.
Most "regular people" belong to the Crafter character class. (Children are still usually unclassified, of course.) Crafters are characters that make things, grow food, or sell things - a merchant is a crafter, in character class terms.

Crafters
Vital Information:
Requirements: 9 Main Skill (see below)
Prime Requisite: n/a
Hit Points: 2d4/level, usually maximum of +2/level CON bonus
Proficiencies:
Start: 2 weapon/6 non-weapon. Only 2 non-weapon proficiencies can be spent on adventuring proficiencies; however, exactly what constitutes an adventuring proficiency may vary from class to class. A smith might be allowed to take Fire-building as a crafting proficiency; a weaver would not, but would likely be allowed Animal Handling (sheep), or another animal suitable to the campaign setting (llamas, camels, etc.).
More in: 1 every 4 levels/3 every 2 levels
Groups: General, any crafting-related
Armor: any, unless multiclassed or GM makes special rule
Weapons: related to craft
Main Skill: Every crafter has a main skill (proficiency) that they use most often - smith, weaver, whatever. Often, some of their other proficiencies are chosen to complement the main skill - for example, Adûriand Nenëa took Weaponsmithing and Blacksmithing, or a weaver who did tapestries might take Artistic Ability. (This is not required - it's just a way of making it make sense.) A crafter's score in a skill is the number must be rolled on a d20 for an unmodified attempt to be successful.
