Physical damage reduction formula (spreadsheet inside)

Right, you can't gain health back if that's what you meant, mitigation can theoretically go only to 100%, and physical mitigation is rock-hard-capped to 90%.

Thanks a lot! Updated the OP with the correct info.

I guess for completion's sake it's worth mentioning that any other Increased/Reduced Damage Taken modifier is additive with Fort's Reduced Damage Taken; most notably Shock and Abyssus fall under this category.

Awesome thanks! I was just going to ask this :)

Armour and Endurance Charges can't be additive.

Armour mitigation scales with flat damage (negative) and Endurance Charges are just % mitigation.

Armour mitigation does scale negatively against damage, as you say. The game takes what would be the resulting mitigation and adds the % from endurance charges before damage is deal. That's my understanding of it.

Abyssus says "Physical damage taken" while the other effects are "reduced physical damage". Fortify says "Physical damage taken". Therefore, abyssus is additive with FORTIFY and not with the armour and endurance charges, etc. If you are going to contradict this, I need a citation for it.

Probably an editing mistake, it was quite clearly stated both here and in that linked thread.

One-shot spreadsheet added! Good luck in not getting one-shot ;)
