Fortify and endurance charge interactions

what is the interaction order of fortify, endurance charge dmg mitigation and armour???

would EC and fortify come before armour? i really hope so, since that means armour actually gets a buff over evasion, instead of hurr durr evasion builds still best.

No, physical damage mitigation from armor is determined first and then mitigation from endurance charges (and soul of steel passive) piled up on top of it to get the final mitigation percentage. There are only two ways to affect incoming physical damage before armor calculation, reducing incoming damage by cursing the monster (enfeeble) and splitting it into physical and elemental parts via lightning coil or cloak of flames.

Fortify is a modifier to damage taken so it will apply after mitigation and additively stack with other bonuses or penalties to damage taken, like vulnerability curse or abyssus.

endurance charges and soul of steel is additive with character armour and all apply at same time. while fortify is a separate buff and its applied before armour.

It happens. That's what you get for not looking into it yourself, the question about defensive sequence is fairly common, answered directly by devs on several occasions.

important part says armor and endurance charge are added and applied at the same time.

so the question is where exactly does fortify enter the equation.

closest thing ive seen is on the awakening skills page it says vigilant strikes fortify buff reduces incoming damage by 25%. so its hard to interpret what which side of the equation "incoming" actually refers to. im going to figure it applies first but someone from GGG needs to give the strait info

In the news post that announced Vigilant Strike, Rory mentioned that the new Fortify buff 'reduces damage taken'. I'm taking that as valid info until I hear otherwise, devs are usually careful with terminology in such posts. On the other hand, they play with skill descriptions on the website fast and loose, for instance, Temporal chains description says that the curse creates a static zone where time passes more slowly, akin to Blade Pact from TL2 :)

Now seriously, so far there were no effects in the game that would apply to you and 'reduce incoming damage', reducing damage output with a debuff was fine, so was reducing damage taken, but reducing damage dealt to you wasn't a thing.

It should parallel the shocked status with that wording. I'm not sure if that comes in before or after armor though.

would be nice if we got an official response, armour kinda needs a buff over evasion c...c
