Personally for hybrids I think Dunmer sorc is best.

Racial passives:
9% max magicka
6% max stamina
And an extra 2% to your shock damage.
Fire resistance.

However if you're set on khajiit:

Vampirism for sustain.

You could ignore crit rating and pick up the Mechanical Acuity set. I'm pretty sure the cooldown starts at the beginning of the effect so you only have 13 seconds downtime on 100% chance to crit instead of 18.

I'd recommend Mechanical Acuity as I used it with my hybrid. With Power Surge and Hurricane active you're basically invincible when it procs.

Rotation will determine your DPS more than anything. But the thing that gimps hybrids is that damage scales from max stat pool. And Khajiit doesn't get a buff to Stamina or Magicka. So a 5/1/1 will be almost necessary (easy if you use a crafted set like Mechanical Acuity or Shacklebreaker) for the undaunted passives.

Then probably run a Stormfist monster helm as it gives 4 chances to proc sorc execute. (3 ticks of shock damage and 1 tick of physical damage)

Alternatively:

You could run 5pc Automaton's and 5 pc Netch's for the 400 extra damage to all physical and shock abilities. + an increase to base weapon and spell damage, max stamina and magicka and extra crit chance.

Though you lose out on 4% extra health from Heavy and Undaunted passives and 2% stamina and magicka. Plus you won't be able to run a monster helm.

Just some suggestions.

Just something I was playing around with: would automaton + warmaiden with 1pc domihaus and 1 piece kena work? Basically two hander automaton with destro warmaiden fire staff on a
dunmer nightblade.

Pump the stats half and half mag with stamina, also tri Stat food for health threshold. Just wondering if this would work.

I'm trying a similar approach on warden. The theory is to use the most powerful ground dots available: endless hail, elemental blockade, winter revenge, caltrops, trap. Combined with shalks and fetcher flies.

I'm focusing on sets that amp both damage. Mechanical acuity allows you to not bother with the major crit buffs. Lover covers pen for both damage types. 3 pc VO or infal will give the 5% dam boost and then wear 1pc Domi, 1pc kena (or a 2pc monster of your choice, like zaan). Triglyphs on big armor pieces, and blue food that boosts Stam+mag.

We'll see how it goes, he's only lvl 33 now.

Edit: Pelinals seems like garbage to me, and I think if you try to use it you will be guaranteed to fail.

When sustain wasn't bad, I had a hybrid dunmer sorc without peinal's. She used 4 WMK, 5 WOF and slimecraw befire it was mainstream. Now it's quite hard to get a decent hybrid that way

So I'm planning a pelinal's hybrid now, 5 pelinals (including nirn bow), 3 agility, 2 Leki and 1 Kena. Max magicka ideally. It gets 3k unbuffed spell/wpn dmg and the chance for a decent shield on medium armor.

Though I'm also considering a WW build using pelinal's and elegance

@JackDaniell video is still the best and the most relevant video and guide to hybrids even today. I used to play around in ESO Build Editor and there is nothing better indeed.

There are two ways:
1) All attributes in Stamina

Gear: 5x Pelinal's Aptitude + 4x Morag Tong + 1x Molag Kena + 1x Velidreth
Classes: Nightblade > Warden >> Sorcerer

It's the most well know build when you stack weapon damage as much as possible.

The main problem of Hybrids is the lack of penetration which means big loss in DPS. To overcome this, you have to rely on your class abilities. That's the reason why those three classes are only good. IMO, I give edge to Nightblade over Warden as after enemy dies Reaper's Mark also heals you for 60% of your max health and gives you Major Berserk for 5 sec. This is big DPS boost. Sorcerer only has access to Major Breach and Warden has Subterranean Assault which like Reaper's Mark has Major Fracture, too.

In Editor, I managed to create pretty respectable Nighblade hybrid. Once I get all the skill points and finish my tank build, I plan to create hybrid as I should have some ~30 spare skill points. Bow + Inferno/Lightning Staff is probably the strongest combo. Also as Nightblade and Soul Harvest slotted you generated crazy amount of ultimate in trash mob fights so you can drop Destruction Staff ultimate more often. That's why IMO is Nightblade class best suited for hybrid in Pelinal setup.

2) Pet build

Gear: 5x Shacklebreaker + 5x Necropotence + 1x Molag Kena ...
Classes: Sorcerer, Warden > Nightblade

It's a pet build when you max your Magicka with Necropotence's 5th bonus. There are variation of this build with both max Stamina or Magicka in attributes plus usage of unique weapons. I don't have access to unique weapons so I won't comment further as would be pointless.

@Lynx7386 you also have access to Bound Armaments as a sorc for the 8% Max Stamina to compliment the magicka from Necro and 11% extra damage from heavy attacks. And having a pet active gives you 8% more Health too.

If we add undaunted passives and assume you are a khajiit running Draugr Hulk and Necropotence 5+5, 5 medium + 2 light + 3 Jewellery:

After 12% stamina boost (undaunted + Armaments) and 4% Magicka boost (undaunted)

Necro gives = ~6500 Magicka
Draugr gives = ~6500 Stamina

That's before food, glyphs + attribute points.

Which will all also get an extra 12% to stamina and health and 4% to Magicka.

If I can get my hands on the gear I might give this a try on my sorc, if only to see if it could work or not.

So thinking atm:

1 maelstrom bow
1 maelstrom lightning staff
5x Hulking Draugr
5x Necropotence

Bow bar:
Razor Caltrops
Rearming Trap
Endless Hail
Bound Armaments
Volatile Familiar

Staff bar:
Lightning Blockade
Liquid lightning
Power Surge
Bound Armaments
Volatile Familiar

Unfortunately nowhere to stick inner light unless we give up power surge / rearming trap or something else. However we could still get 3% more max magicka if we slot meteor on both bars for the ultimate. might be better off to go with atronach + suppression field instead though, since you still get 2% spell/weapon damage from passives that way and it gives you good aoe and single target damage options.

EDIT:

Actually, inner light really only needs to be slotted on the staff bar because it's not a toggle, so I guess we could slot it there instead of power surge and then put power surge in rearming trap's place on the back bar, but that's giving up a good bit of damage over time and minor force for some spell crit and max magicka... not sure it's worth it.

Also this build is going to suffer with survivability because there's no room on either bar for hardened ward =/
I wonder if it's worth while to fit overload onto one of the bars to give access to a third bar with the ultimate?

Yes, Necropotence pet combo. It's even possible with Nightblade as Shade summon(s) is/are pet(s). Shadow Image is IMO better morph but both basic ability and morphs apply Minor Maim on hit. Still, I wouldn't bother with it as duration is ~21 sec but they can't die so there are always trade offs.

@Lynx7386

I guess you use ESO Build Editor, right? Don't waste time and money on obtaining gear when can you simulate them properly.

Anyway, my proposed Nightblade classical build. I am almost CP400 with CP optimized for stamina DD.
I am Bosmer and attributtes are +7 health and +57 stamina.

Gear
5x Pelinal's Aptitude + 4x Morag Tong + 1x Molag Kena + 1x Velidreth

Armor is divine medium. Chest is heavy and one small piece is light.
Glyphs: head, chest and legs have prismatic glyphs. One small have stamina and 3x small have health glyphs.

Why? Because using prismatic in everything is very pricy and you have to use pricier 3x max health + stamina + magicka food. This way I save money on runes and use cheap 2x max stamina + magicka food.

My stats are (2x max stamina + magicka food): 17,3k health + 19,4k magicka + 31,757k stamina.
Magicka recovery is 747 and stamina recovery is 1073.
Weapon damage: 3.246 (front bar) / 3.333 (back bar)
Spell/Weapon Critical Damage is 60/73%.

Off course you can play with glyphs and food and tune to your own preferance.

Skills
1) Inferno/Lightning Staff (nirnhoned)
Elemental Blockade - Reaper's Mark - Relentless Focus - Leeching Strikes - Inner Light / Elemental Rage
2) Bow (nirnhoned)
Endless Hail - Poison Injection - Killer's Blade - Rearming Trap - Razor Caltrops / Soul Harvest

Weapon traits: sharpened or nirnhoned? Sharpened gives ~2% better DPS on bow bar according to Build Editor. Nirnhoned is expensive but if you slot heal ability… Basically, on the bow bar you can run whatever better suit you. On the front bar, difference is just 1%.

Overland content (alternative skills and gear)
For the overland content and eaiser group dungeons, there is another fun and good alternative. Instead of Morag Tong and one monster piece, use Shadow of the Red Mountain set. Also you can add Acid Spray on back bar instead of Killer Blade or Rearming Trap. With so many active DoTs, volcano is processed very often.
Shadow of the Red Mountain set is even better on Warden.

Buffs
You have permanent Major Prophecy on the front bar.
Once you deal critical damage (guaranteed from sneak), you gain Minor Savagery for 20 sec (Hemorrhage).
Activating Relentless Focus you gain Minor Berserk and Minor Endurance for 20 sec.
Major Breach and Major Fracture are gained by Repear's Mark. It lasts 20 sec on enemy and after enemy is dead you gain Major Berserk for 5 sec.
Rearming Trap gives Minor Force after triggered (2x 6 sec).

Potion
Essence of Weapon Power (Blessed Thistle + Dragonthorn).
It restores Stamina, and you get Major Endurance and Major Brutality which automatically translates into Major Sorcery.
If you add Namira's Rot or Scrib Jelly, you gain Major Expedition, too which is not mandatory as you can get it from Bow passive when you roll dodge but it lasts 5 sec as opposed to 36,6 sec.

Hope it helps somebody . Of course, suggestions are welcomed.
If everything goes well, I should run this setup in a one month.

Poison
You can use Drain Health Poison IX (Fleshfly Larva + Nightshade + Blessed Thistle or Nirnroot or Violet Coprinus) on your bow bar for the additional DPS.

EDIT
Added additional info, some fixes and spelling fix.

EDIT 2
Added weapon traits, overland content and poisons.

I updated post. I accidentally ommited - with slotted Magelight (and its morphs) you gain Major Prophecy. Sorry for accidental misinformation!

For potions use Essence of Weapon Power (Blessed Thistle + Dragonthorn).
It restores Stamina, and you get Major Endurance and Major Brutality which automatically translates into Major Sorcery.
If you add Namira's Rot or Scrib Jelly, you gain Major Expedition, too which is not mandatory as you can get it from Bow passive when you roll dodge but it lasts 5 sec as opposed to 36,6 sec.

Not sure if OP was looking for PvP feedback, but I'm adding my info, even though it's not the "hybrid" classification currently being used (where people stack DMG and use pelinals).

Lately there have been some Templar builds floating around between some of us magplar mains. We have been tired of playing a class that lost miss chance, has no aoe defense, no escape mechanic and trying to play builds that had conflicted synergies (jabs channels stopping you from blocking with SnB/frost staff, channels/heals being useless while in mist form, etc).
Therefore, some of us had been looking for anything that could work. Lately we have been slotting anything with major evasion.

What does this have to do with hybrids? Major evasion outside of sets, can only come from medium armor now. But as others have said, crit chance and penetration are the two stats you lose out on heavily (and arguably the most important in PvP). If you want crit outside of light armor, you need 3 crit stats on your set pieces to reach a minimum of 40% crit chance. Penetration, sadly, can only come from using ele drain plus some points into spell erosion (or sharpened trait, but I feel you lose too much SD and are subject to being weak against shields).

Slimecraw, innate axiom medium armor, and transmutation will give you the crit past 40%, ele drain on backbar frost staff will give you extra sustain and 5280 penetration, and that leaves you the options to find sustain+ raw DMG. But you do lose out on a proc set like zaan or valkyn (zaan might be good here because it also gives you enough spell crit to stay above 40% while also giving some free proc DMG).

For raw DMG, you'll need to go dual weld using infused off hand and nirn main. You'll be below 3k unless you do. Enchant for infused will be shock for the vulnerability stats effect and DMG enchant on the main sword to help keep your weapon DMG up. Use poisons on the frost staff; immobilze+Stam cost are my favorite ones to use.

For sustain, atro + 2 mag regen (or cost reduction) plus ele drain and a class Regen ability (Templar uses channeled focus). You'll be at around 1300 before ele drain, which puts you chooser to 1800 which then channeled focus puts you closer to 2k we see on be these days. Tri food or witch mother's.

Medium armor will give your mag build the following:
- 20% Dodge roll reduction
- 15% Sprint speed boost
- 10% stamina cost reduction (for shuffle use)
- 20% stamina Regen (use speed pots that give major Endurance and immovable to really save stamina for defense).

Those passives alone outweighs the penetration you get from LA (because a mag builds weakness is mobilty+low stamina pools). And the crit+sustain is going elsewhere, so you'll only be missing out on the cost reduction (but if you are a breton templar, you'll be at 9% cost reduction in MA compared to 16% in LA, which is a 7% loss.)

The conclusion:
- hybrid can also be deciding which bar does what. If your stamina bar is defense then your mag bar is offense/heals.
- the only pure stat classes are currently magblade, all stamina classes, and magsorc. Reason being, only Sorc/NB can stack max mag stats while being able to survive with low Stam pools. Magplar/MDK/magden have to build with stamina burns in mind, and therefore are now hybrid than most players like to think (though magden has major Endurance built into their kit, they are also stack max stats, but they don't have the escape options as NB/Sorc to justify low Stam.)

I think we will be seeing unique builds shortly. Thanks for the thread!

It will bring more options. But It will not push them to vet trial level all of a sudden. However, just like every patch I‘m gonna burn a huge amount of gold to see how they fare this time.

JC opens up the possibility to bank on big res pools instead of pelinal + wpn dmg on my build ideas. I‘m going for shackle + TBS (max stam + mag mundus) with 1 domi & Kena on a dunmer sorc. Statswise it should bring both to low 30s. From there on starts the shifting and testing.

PvP is completely different beast . After all, Shacklebreaker is pure hybrid set and it's pretty popular in PvP, but you already know that.

I'll repeat - build viability for HM trials is already very limited. For the vast amount players i.e. casuals / plebs like me (who doesn't care about leaderboards; heck I don't even play trials at all), changes are welcomed and in good direction .
