Farming gear in ESO is relatively easy in compared to other mmo's.

This is due to the stickerbook and transmute system.
You'll generally gain gear that you don't have unlocked in your stickerbook system yet when farming a dungeon or trial. so eventually you'll get the items you want.

Traditional setups usually had:
2x monster set,
5x DPS set
5x Sustain set
An arena weapon.


Alternatively you can replace 1 5x set, or a monster set for a mythic item. (such as oakensoal, harpooners kilt etc.)


Nowadays sustain isn't that much of an issue anymore, so people generally build:
2x monster set
5x Dps set
5x Dps set
backbar using a vMA greatsword (for the stampede dot/aoe)

You could use a mythic item however it's not the "best" anymore.

It really doesn't matter that much which dps sets you use really. the difference is a few %%.
You could simply start with 2x zaan(Monster set), 5x Julianos(Crafted set) 4x New moon acolyte (crafted set) or mother's sorrow(Overland set) and oakensoal (because you want a 1 bar build)

Alternatively 1x Monster set that gives base stats such as extra magicka, or crit chance. 5x Julianos 5x mother's sorrow/new moon acolyte, and oakensoal.

That gives you a good basis, from there you can farm other gear that you want such as the gear suggested there, but to be frankly for 99% of the content that setup would be sufficient.
A good replacement set that doesn't require trials would be pillar of nirn, (which would replace julianos in this case)


Skill bar wise;

Generally back bar= full of aoe/dots/buffs.
Front bar= more dots, 1x spammable 1x Execute, sometimes depending on classs a "Procable high dmg skill" such as blastbones for necromancer or bow for nightblade. and some skills that passively boost your dps, such as "Camouflaged hunter" or "inner light".

As a 1 bar build you need to make your build much more compact.
So generally you'll have 2-3 dots, 1 spammable, a class procable if applicable (for necro that'd be your blastbones)

I'd personally do the build a bit different than what azryal suggests. as I would make it;

- Avid boneyard (Aoe/dot)
- stalking blastbones (Proc dmg)
- Ricochet skull (Main spammable) alternatives are; force pulse(bit more aoe dmg, less single target dmg), or elemental weapon(easier on sustain, but lower dmg)
- Skeletal arcanist (Sustain+dot dmg)
- Detonating siphon (Aoe dmg)
- Ult: Colossus.

If you have problems with sustain you could potentially use hungry scythe instead of ricochet skull, it gives more aoe damage and allows you to use the passives of bone tyrant, which gives extra health, magicka/stamina regen healing received and the skill itself heals you as well. however it requires you to be in melee range, and it's less single target dps than ricochet skull. so I'd only use that in aoe heavy fights/in places where you need the extra survivability. in most cases simply using ricochet skull is better.

As for rotation/skill priority; Always keep your arcanist up, keep your dots up, activate blastbones whenever it's available (after every 2 casts)
And when no other skills need refreshing/blastbones isn't available use ricochet skull.

Always use a light or heavy attack before each attack. I'd suggest just going inferno staff. since it is ranged and does good damage. (Technically daggers are higher damage, however you'd need to be in melee range to use the light/heavy attacks. so inferno staff is a lot more beginner friendly.)

Start off with gear you can get and use it to work up to gear you want. For instance, that build says Whorl and Order's Wrath. Order's Wrath is craftable, so that's easy. Whorl is from Dreadsail Reef. You can get a non-perfected set on normal that works just fine. A solid non-trial set is Deadly Strike, which you can buy from guild traders. Or Frostbite, as that build suggests. Frostbite is pretty cheap.

The real key to DPS is not gear, however. Its your rotation. You can have the best gear in the game, and someone who has a better rotation can out-hit your with base sets. That is not to say gear plays no role, it does, but the improvement you see from top sets is much larger with a solid rotation than a junky one.
