So, stupid question wandering my mind: How much strength increase does a +1 represent?

How much stronger than a normal human is a giant?

What of someone with Str+5?

Forewarning: I probably made some mistakes, but I have full confidence that these will be corrected, meaning we'll end up with a workable answer anyway.

IIRC, while weight increase is based on size increase cubed, strength increase follows the square cube law.

I remembered that +3 size meant x10 weight.

If we consider that +3 size also means +6 Strength

While weight went x10, Strength went about *4,6 (cubic root of 10, squared).

Thus, someone with +6 strength would be 4,6 times as strong as someone with Strength 0.

What of other strengths?

Just to check, I took a look at the size table in ROP: Magic.

Serf's parma, but IIRC, for size +1 to +4, each size increase was about weight *2,15, which made sense: It is the square root of 10, meaning that +3 size was 2.152.15*2.15 = *10 weight.

This roughly held up for all the table, up to size +20, save one weird disconnect at size +10, which is only weight *1,16 compared to the previous entry.

Pardon me if I choose to ignore this.

So, going with this idea and rough numbers:

+1 size = weight *2.15 means +2 Str = strength * 1,67

Going with that idea, someone with Str +4 is 2,79 times as strong as someone with Str +0.

I'm kinda disappointed: I expected mythic strength (+5) to be outside the bounds of normal humanity, whereas, afaict, it roughly tracks with difference between average and world record of bench press capacity.

But back on track.

I could try to figure out what a +1 Str means, but I'm tired and have work waiting

Still, how much stronger than a normal human is my giant?

If each +2 Str is about *1.67 "power", we get something like this:

Str Score | Rough strength increase |
---|---|

2 | 1,67 |

4 | 2,77 |

6 | 4,62 |

8 | 7,70 |

10 | 12,83 |

12 | 21,37 |

14 | 35,59 |

16 | 59,29 |

18 | 98,77 |

20 | 164,53 |

22 | 274,08 |

24 | 456,57 |

26 | 760,56 |

28 | 1 266,95 |

30 | 2 110,50 |

32 | 3 515,69 |

34 | 5 856,47 |

36 | 9 755,77 |

38 | 16 251,26 |

40 | 27 071,53 |

So now that I've wasted half an hour (discounting time at home) on this silly question, I'll leave it to you to poke fun at
