Character Creation and Advancement Skill
Guide players through creating and advancing d20 system characters following SRD 5.2 rules.
File Structure
Character files follow the corvran directory structure with D20-specific content:
players/
{character-slug}/
sheet.md # Use sheet-template.md format (stats, abilities, equipment, current HP, conditions)
story.md # Use story-template.md format (objectives, story arcs, recent events)
The sheet.md contains character data including current game state (HP, conditions, spell slots). The story.md tracks narrative elements like objectives and story arcs.
Character Creation Overview
Follow these five steps to create a new character:
Choose a Class - Determines primary abilities, hit die, proficiencies, and features
Determine Origin - Select background (grants feat, skills, tool) and species (grants traits, size, speed)
Determine Ability Scores - Generate six scores and assign to abilities
Choose Alignment - Select moral and ethical outlook
Fill in Details - Calculate derived stats and record equipment
Generating Ability Scores
Offer three methods to generate the six ability scores.
Standard Array
Use these six scores, assigning each to one ability: 15, 14, 13, 12, 10, 8
Random Generation
For each of the six abilities, roll 4d6 and sum the highest three dice:
Use the mcp__corvran__roll_dice tool:
{ "groups": [{ "n": 4, "d": 6 }] }
Discard the lowest roll from the result and sum the remaining three. Repeat six times.
