Sacred Soil description?

[Rongway]

Also Kaynide, as far as damage calcs go, it's the latter way you describe for everything as far as I am aware. Starting with the highest mit, they have diminishing returns on down the line. Such that you can't actually achieve 100% mitigation, making HP shields required to reduce damage to zero.

Like I remember back in Stormblood on DRK vs. Exdeath Savage, I could nullify Thunder III x2 without an immunity by stacking everything and kitchen sink with Blackest Night used as the first thunder hit. After everything, DA + Dark Mind, Shadow Wall, Rampart, Reprisal, and Addle, I only had something like +87.2% mitigation, rather than 100%.

This is not due to reducing stacked effects but due to multiplicity of effects. It won't matter what order you apply the buff multipliers because multiplication is commutative. This means that A x B x C is the same as C x B x A.

In your particular example (using historical 2018 values),

             % reduced    as a multiplier
Dark Arts    30           0.7
Shadow Wall  30           0.7
Rampart      20           0.8
Reprisal     10           0.9
Addle        10           0.9

                Product:  0.31752

That is, even though the percentages add up to 100%, you would still take about 32% damage while all those effects are active.

Yeah, so it's never additive, right? Also I forgot grit, so I guess it'd be 0.254016. Not sure what math I was doing back then. Even with Apoc it's right around still taking 20%
