See, at some point I had seen Paizo's Steel Sqwire templates. I judged them unnecessarily expensive, because I knew I could make some that were just as good myself.

So I went and I found some wire...

...and did some calculations.

I decided that all the fiddly little right angles and squarenesses in the RAW templates for cones and bursts were unnecessary, because I was making templates to represent actual cone and burst shapes. I decided my cones would be quarter-circles and my spheres would be circles! So that involved some math.

As everyone should know from elementary school, the circumference of a circle is 2πr. And, obviously, the perimeter of a quarter-circle is 2πr divided by 4, plus 2r, or r(π/2+2). And 1 inch for a mini equals 5 feet in-character, so we divide all our answers by 5.

radius
(ft.) |
cone (in.) |
burst (in.) |

10 | 7.1 | 12.6 |

15 | 10.7 | 18.8 |

20 | 14.3 | 25.1 |

30 | 21.4 | 37.7 |

40 | 28.6 | 50.3 |

50 | 35.7 | 62.8 |

60 | 42.8 | 75.4 |

70 | 50.0 | 88.0 |

I elected to make a 20' burst and a 30' cone, because those are the biggest that would fit in my D&D stuff carrying folder, and anything smaller is easy enough to figure out on the fly.

So I cut my wire to length and affixed it to itself with a connector and...

This dragon's breath weapon is 10' too short for its size. Oops. |

Easy!
