Do "Resist" mods stack?

[Malidictus]

So I've been doing a bit of spring cleaning on my armour mods now that I have a decent selection, and found a lot of Minor Resist mods in everything. I put those in because I genuinely didn't have anything better at the time, but it made me wonder how these mods even work. I did some Googling and got inconsistent results. So, question time:

How much damage resistance does Minor Resistance offer? Google results mention anything from 10% to 15% damage resistance, though they measure this off pixels on the screen and some of those articles are pretty old. This may have changed with Shadowkeep. Is there any point in slotting Minor Resist in more than one armour piece?

Do Minor Resist mods stack together? If one mod hypothetically reduces incoming "rank and file" damage by 10%, would four of them resist it by 40%, i.e. four times as much? Or it it a waste to slot more than one of those? As I said - I have them slotted in every piece of my gear, so I wonder if that's a waste of slots.

Are Minor Resist mods worth slotting at all, when I could be slotting Resilience or Recovery mods? I know the Resilience stat doesn't actually do all that much (it boosts my total shield by up to 10% for 100 Resilience, if I recall) while these various resistance mods individually might offer more return. Of course, SOME resilience on top of SOME of these would be ideal because bonus shield would stack multiplicatively with bonus resistance. Two stacks of 10% would offer 21% damage resistance, so slightly more than a single 20% stack.

I honestly wish the game offered more numbers with which to make informed decisions...

I would assume it is like a lot of other things in-game, in that it stacks but with diminishing returns. but it should be easy enough to test by, putting on one mod, go somewhere with a single minor combatant... tangled shore near spider seems like a good spot, see what kind of damage a specific mob does, then repeat with all the mods on.

As it stands right now until mods/elements are changed on armor. Your mods stack as a x2, so you get 10 discipline per mod increased, but after the change (Which is suppose to allow you to put any mod on anypiece of armor, none of this solar, void etc stuff anymore.) it changes ti a dimishing return starting at 1.5x. Or something like that.

Is the removal of elemental mods confirmed? Is there an official link somewhere? I hope this is true!

Right, but that's for major stats, your Mobility/Resilience/Recover/etc. What about Minor/Major/Boss resist, though? I ask, because I found a thread on a random forum listed as "3 weeks ago" which stipulated that Minor Resist is about 10% and does not change with additional mods slotted on other items. I suppose I can try it, but a 10% damage resistance value against weak enemies would be pretty hard to track precisely. Suppose I could film it and count pixels like other people have done, but I was hoping someone knew that for certain. Again, what's the harm of giving players accurate information?

As to getting rid of armour elements, uh... Seriously? If so, that would be absolutely awesome! :) I really dislike that system, largely because it adds another unnecessary RNG element to proceedings but also because it really doesn't add anything to the experience. I've yet to see a combination of mods I wanted SO badly but couldn't get because they were different elements. Hope that bit is indeed true. And yes, I'll take diminishing returns for it. Generally speaking, I'm not a fan of over-stacking the same buff multiple times, as that has the effect of VASTLY reducing build diversity.

It's been a few days, but I got around to testing this myself. Here's what I found:

This is a screenshot of me having taken a single shot from the same one enemy (some kind of Scorn rank and file) at the same distance from full health. This was a sniper style enemy, so I could easily crouch behind cover to regen health and he would stay put to ensure consistent range. From top to bottom, the first health bar is me having taken a shot from that enemy with no Minor Resist mods installed at all. As you can see, I'm missing slightly more health than the other cases. The reas of the health bars are me with one Minor Resist mod installed in my helmet, two Minor Resist mods (helmet and chest) and three Minor Resist mods (helmet, chest and arms). I tried this with a few permuation and it doesn't seem to matter which pieces hold the mods.

I took less damage with 1, 2 and 3 Minor Resist mods. Crucially, I took THE SAME amount of damage with 1, 2 and 3 Minor Resist mods. Granted, I'm eyeballing the health bars so there might be half a pixel's worth of difference between the examples, but if there is it's too low to matter. Near as I can tell, Minor/Major/Boss Resist mods do not stack together and there's no reason to slot more than one. What this means is it's smarter for me to ditch two of my three Minor Resist mods and maybe replace them with a Major Resist and a Boss Resist mod, so I take slightly less damage from those, as well.

*edit*
For some added info, I measured pixel widths. After being shot in rows 2,3 and 4, I'm left with just about exactly 336 pixels' worth of health from a total of 434 at full health at my native resolution. I've taken 98 points of damage. After being shot in row 1, I'm left with 326 pixels of health out of 434, having taken 108 pixels of damage. By my rough math, Minor Resist reduces rank and file damage by ~9.26%. Accounting for the imprecision of my measurement approach (I may have measured a little wide), I'm going to have to agree with the random Google result I found which suggested 10% damage resistance. That's not a lot, but it's not nothing.

Long story short, Minor Resist mods offer ~10% damage resistance and don't stack if you have more than one of them equipped.
