Fortified brass

mikey_reach · November 2017

Is it just me or does this crafted set seems better what what it is? For example me magplar 5L 1H 1M is sitting at 26k spell resist and 22k phys resist sustain is no problem and when its fully buffed spell damage is 4.5k and mag is 35k it just opens up many posibilities. That was just my examole based on one build. What do u guys think?

VaranisArano · November 2017

Fortified Brass is a very effective way to stack a lot of physical and spell resistance in any weight of armor, which makes a lot of sense when you consider that it came out in the same patch as ZOS required players to wear five pieces of an armor weight in order to use the armor skills.

If you need more resistances and are willing to spend a 5-piece gear set to get them, Fortified Brass is an excellent choice. If you aren't, its not. You can get the same effect for the 2-piece Mighty Chudan monster helm, but there again you have to make a choice of that helm over another, perhaps better monster helm.

I guess reposte might better my problem is that im pretty bad at shield builds so i guess i ended up going this route,plus if u have no shield that opens up a new skill slot so it seems like a good tradeoff.

TheDoomsdayMonster · November 2017

I have been thinking hard on wearing this and Mighty Chudan...

I'd have 37k Spell Resist and 29k Physical Resist at all times on a 5 light, 1 medium, 1 heavy set up...

This is very, very, very tempting...

You can also do x4, with the 5th being a weapon on one bar, allowing for a lot of variations.

What it does for light or heavy, is pretty much make you heavy with that armor's passives.

If you want a comparison it remind me of running the old Black Rose

Did they change 2p might chudan? What I remember, is, that it grants u major resolve/ward, but most classes have an armor buff ?

It saves you three GCD in casting that buff. Also some classes have a bit more stricter condition for that buff. Like DKs their spell can be costly, NB have to cast a shadow ability, etc.

It really comes down to your bar and what you realistically are going to be casting.

That 5th weapon swap setup gives you the old defending trait resists. Great for builds that will be waiting on their backbar for burst.

And I think it comes down to what the full resists give you. If you can get 22k resists, you'll be sitting at 10% mitigation after a 15280 debuff. Letting you start to boost other stats.

I did ask myself, e.g. for Templar (5light/2heavy)

5x trans (Front or back)
5x WR (Front or back)
2x any set (Torso + legs heavy)
2x valkyn skoria, any Monster

I find this setup quite strong, u can personal adjust it with mundus/glyphs etc. Well, keep in mind, this is not for a "blockplar", i personally run serpent and Dodge/mist rather than block.

I tried this set on my stamDk because every single pug in this game sweared Its the best medium set ever.
So the result is:

Meh. Just... meh..

made me ask myself Why am I not just running heavy armor instead.
All the day.

I mean I have high resistances but:

I lack constution ( this is especially noticeable when Im blocking)
I lack hp (and It makes me feel really easy to get bursted,barely 22k hp in vivec, and my stamsorc friend has like 29k hp with much better burst overall)
I lack healing (less healing, more vigor spams, It just makes life harder)
I lack weapon damage (If medium gave 5k flat pen instead then my damage would be probably better)
I lack heavy attack resource return (this one especially hurts because sword and shield builds do really need that extra heavy attack returns)

So using medium armor and pretending Im wearing heavy, didnt work, at all.
I had 30/27k resistances, 1800 ish crit resist, yet I was getting bursted down in seconds anyways.
I had to play like I was some kind of glass cannon build.
A stamblade managed to dizzy swing me for 7k.

The resistance cap is around 33K, so unless you are in PVP dealing with people overpenetrating your armor, you don't need to stack physical resistance that high.

Makes sense since stamina synergizes better with heavy anyways but with a magplar is a ehole diferent story i mainly mist and roll since u can recover magicka as a magplar anyways healing is fine health is at 23k which im used to spell damage is 4.5 and spell pen is 9.5k. My friend also didnt find it to effective on stam but on magicka builds like magplar and magdk it works pretty well. And for a non meta set you cant really ask for more.

I don't think it made sense after gutting one of the skills from 1H+Shield and then splitting another so that the illusion of a similar number of passives could exist.

CP or no cp?
Having high resist and such doesn't mean anything unless you have a proper CP setup. What do you have in Ironclad, Elemental Defender and Hardy?

From a pure, personal defense standpoint, Brass is superior unless you're a mag sorc. Riposte gives 15% mitigation with diminishing returns, for a real value of ~10% on most light armor builds whereas brass adds 12.34% with no diminishing returns. If you're stacking shields then the 15% is nice, but if you're vamp then undeath will add more diminishing returns on riposte since its another % based reduction. Furthermore, riposte's value is reduced further by the presence of other sources of maim.

The advantages of riposte are that the long proc time allows you to run it as a back bar set, allowing you to run 5/5/2 on destro/resto builds and 5/5/2/1 on builds that back bar SnB, whereas brass needs to be active on both bars so you've got less options of where to pair it. It also will provide the damage reduction to your group

On my magplar I did light armor and paired it with lich and valkyn skoria I had good damage and good survivability, I think I’m a below average magplar too so I think you could prob switch lich for a damage set

On my stam dk I did medium and paired it with slime crawl/ blood spawn, agility and 2 piece seventh legion on my front bar. I had good damage very tanky and it works in both cp and non cp

Who would use Fortified Brass outside of pvp anyway? Find me a serious pve healer who doesnt have a hard on for SPC, or a pve dps without a similar hard on for julianos/hundings/whatever.

Tanks dont need it in pve, and no other pve role wants to sacrifice their epeen numbers to be able to take a hit.

You are right, high physical attacks isn't always better. Bleeds ruin this hard. But still, if you can get 18-22k without giving up DMG/other CP placement, that's much better than running out of breath trying to get high physical resists in LA.

Spell resists on the other hand, resist everything. Only downside is 10% destro penetration from it's main spamable + main cc which are plentiful. Combined with ele drain, you could look at a incoming debuff of 17880 penetration; but with 26k spell resists you still have a 12% mitigation whereas physical is limited by lower base availability, bleeding and penetration.

Still I want to see that dude's CP and a PvP video lol.

@Lexxypwns Wizard's riposte has diminishing returns? So if someone hits for 1000, then Riposte procs maim, the next hit will be more than 850?

Yes, unless you have no armor/spell resist or other % based mitigations. Although, the hit that procs riposte receives the maim bonus so the initial hit would not deal the full damage either, that's what makes it such a viable anti-gank option

I recommend you read http://freetoplaymmorpgs.com/elder-scrolls-online/damage-mitigation-explanation-updated-for-morrowind-new-calculator its a wonderfully written explanation of mitigation in ESO, complete with formulas and a calculator written by @paulsimonps

Riposte is still very strong because its essentially an aoe mitigation tool and because its an excellent back bar set that allows you to have uptime when you leave the bar due to its nice long debuff time. It's outperformed by transmutation on non-shield stacking builds in most cases though.

It still does 15% reduction. But if you add more sources of reduction, the next reduction will be a % of the lower DMG that was reduced by minor maim.

Think of it this way, you eat a pizza pie but you only have 3 slices. Now your friend can eat the same amount, but they aren't eating the full 8 slice pizza pie you started, they are eating out of the 5 slices that you left behind.

But in this case there aren't percentages, which per basic math, are usually always better the higher the number you are trying to reduce. Like how 10% of $100 would be 10 dollars saved, but using the 20 coupon would mean you could have saved 20%. If the amount was $300 instead of 100, you would have saved 30% total (which accounts to a Delta of 10%).

These two concepts combined is what Lexxypwns is taking about. Wizard might give 15% reduction on DMG, but if you have 20% Ironclad, wizard is taking a 15% reduction after Ironclad kicks in.

WrathOfInnos · November 2017

@Lexxypwns and @Minno

Thanks for clarifying. That is how I thought it worked, minor maim is multiplicative with any other bonuses. So whatever damage you are taking with all your other forms of mitigation, you will be taking 85% of that value after Riposte procs.

I wouldn't really call that diminishing return though, since the tooltip 15% is always accurate. IMO diminishing return would be something like the Heavy Weapons passive claiming Greatsword's get 5% increased damage, but instead they get closer to 3% damage because they are additive with other % bonuses. I think all the % bonuses should work like maim, multiplicative and independent of other buffs/debuffs.

Let's take the 1k tooltip - with no other sources of mitigation, riposte turns it to 850, meaning it prevents 150 damage.

Now 1k tooltip - 10% into ironclad - 900 damage - 5% ele defender - 855 damage - 15% maim - 762.75 damage. In this case riposte only prevents ~93 damage, therefore making it less appealing.

Though I'm curious what happens if wizards is placed first. Is there a priority? For example, is CP first followed by status effects? If so, then wizard suffers from diminishing returns. If not, then CP suffers from more.

I know Paul's thread treats this all in the same equation, as long as they are from the same grouping and side of the equation.

Regardless, stacking percentage based mitigation causes diminishing returns and the efficiency of said % based mitigations in the CP system compared to the other mitigation options in the warrior tree means that you should never change your CP layout significantly to compensate for riposte.

It also means that riposte will have its greatest effect on mag sorcs since they usually use more points into bastion and will sometimes use resistant to get the crit resist they're looking for while using infused/divines armor pieces(I advise against this, but to each their own). Then factor in that you don't need vamp and therefore won't have the undeath passive and you're looking at potentially having less % based mitigation than most magika specs.
