Could someone check my math and confirm? From what I can tell, a few points into damage penetration (on skill tree) at 10% penetration each, is very much worth it but after investing a few it certainly has diminishing returns.

My conclusion, always invest up to around 20% but more than that and it starts to not be worth it. Early on every 1% pen is basically a 1.4% MORE damage multiplier (10% pen = 14% more damage), but at 20% it becomes 1.2% MORE each and at 40% it becomes 1:1.

Not sure how to enter excel data or fancy information so I will copy paste below showing numbers. Keep in mind %MORE is relative to the previous investment in penetration and not a running total.

Damage | Pen | Resist | Total Dam | %more |
---|---|---|---|---|

100 | 10 | 30 | 80 | 14.28571429 |

100 | 20 | 30 | 90 | 12.5 |

100 | 30 | 30 | 100 | 11.11111111 |

100 | 40 | 30 | 110 | 10 |

100 | 60 | 30 | 130 | 8.333333333 |

100 | 70 | 30 | 140 | 7.692307692 |

100 | 80 | 30 | 150 | 7.142857143 |

100 | 90 | 30 | 160 | 6.666666667 |

100 | 100 | 30 | 170 | 6.25 |

100 | 110 | 30 | 180 | 5.882352941 |

100 | 120 | 30 | 190 | 5.555555556 |

100 | 130 | 30 | 200 | 5.263157895 |

100 | 140 | 30 | 210 | 5 |

Would love to hear other opinions on this. Especially when to strike a balance between crit multi and ele pen (two huge damage sources) and how much to shoot for of each. I’m thinking intuitively, max crit multi but first try to hit that 20% penetration figure.

Total damage calc is as follows: Damage*(1-((Resist-Penetration)/100))

% more damage calc is as follows: (Total Damage - Previous Total Damage)/Previous Total Damage*100

Cheers!
