1. Determine Required Skills

Design skills from Engineering Triad

2. GM assigns complexity

Complexity Required Skill Level Retail Price
Simple 14 or less Up to $100
Average 15-17 Up to $10,000
Complex 18-20 Up to $1,000,000
Amazing 21 or more Over $1,000,000

3. Concept Roll

GM roll vs. Character Skill to determine if theory is testable.

Modifiers:

  • -6 if the invention is Simple, -10 if Average, -14 if Complex, or -22 if Amazing.
  • +5 if you have a working model you’re trying to copy, or
  • +2 if the device already exists but you don’t have a model
  • +1 to +5 if the item is a variant on a existing one
  • -5 if the basic technology is totally new to the campaign (regardless of TL)
  • -5 if the device is one TL above the inventor’s TL.

On success, inventor has successful theory and may proceed to Constructing Prototype.

On failure, inventor knows his theory is bad and may roll again next day.

On critical failure, the inventor thinks he has a workable theory and proceeds to Construct Prototype.

4. Construct Prototype

Roll vs. inventor’s skill. Use same modifiers as Concept roll, plus:

  • +1 per assistant with skill 15+ (max: +4)

Each Prototype roll requires 1d-2 days if the invention is Simple, 2d days if Average, 1d months if Complex, or 3d months if Amazing.

5. Cost

The prohibitive costs of engineering require a Patron or Wealth 1 or greater.
