[3.3] Pure Fire EleHit Berserker | 880k consistent shaper dps (without BiS gear!)

The budget version uses only few/cheap unique items.

Weapons
As I do not stack any accuracy, I need to make up for it somewhere else. The obvious choice is the shield Lycosidae, while using some high attackspeed weapon like Brightbeak. But as the shield is rather expensive atm, I chose two 100% hit daggers instead. Alternatively you can use a Vagan mod weapon or a shield with life an res, but I would not really recommend it as comparable items are difficult to obtain.


Helm
As the helm I chose Starkonjas, as it provides high life, some attack speed and maybe most importantly some needed dexterity (EleHit need 155 dex at lvl 20). You can also use some rare helm with life and resistances, but it makes it more difficult to get all the dex needed.


Body Armour
The body armour is one of you choice. Initially I used a rare 5-Link with a %Life mod from the Temple. Afterwards I switched to a Loreweave as I had enough rings to get me one (honeslty...it didn't even feel so much better or safer). You can basically choose what you want/need here, as long as it has enough links.


Rings
The rings have to be Pyre and Call of the Brotherhood to get the (almost) 100% Fire conversion. If you REALLY want, you can use a Cold to Fire Gem instead of a Pyre, but it was only 1c when build my char and gibes the space to use a different support gem.


Amulet
You have some options here. You can go for a Yoke of Suffering, which should boost the damage the most on a budget but you can also invest a few chaos more and get a rare with life, wed and res if you need. Both should work.


Gloves
For the gloves I chose 1-Abyss-Socket Tombfist Gloves, mainly to intimidate enemys. They were 2c when I bought them.
You can also use rare gloves, but according to PoB Tombfists were only competing with very very good rares, costing a few ex. As for the murderous eye jewel, look for qol stats (life, attack speed on crit, onslaught on kill, ...). (Ignore the curse on the linked gloves)


Boots
Some rare Boots with resistances and life are what you want here. If you can cap your resistances elsewhere, go for Kaoms Roots for the high life. You dont need any movement speed here as you will only move with the movement skill of you choice (depending on your weapon choice of course).


Belt
Go for a rare belt with resistances, life and weapon elemental damage in that order.


Jewels
Aside from the two Combat Focus jewels, got for rare jewels with %life, melee damage, fire damage, attack speed, etc. If you need, you can also fix your resistances with the jewels.

The expensive version was used when I killed Shaper. There might be more suitable items that I did not think of/I did not try, but it works as it is. Test some different stuff if you can!

Weapons
To get the 100% hit chance I went for a Lycosidae (it also provides some life!) and a Brightbeak for its high attack speed. I think the only weapon giving more dps is a rare weapon with very high attack speed, wed, high elemental damage. When I build my character, the cheapest weapon like this was 2ex and only gave something like 2-3% more damage. For me it was not worth it.
An alternative to mix things up a little (mainly to make the build tankier) is to use bloodseeker for the instant leech. This works especially well with the savage hit leech, but makes the build a little slower. If you have the money, go for an attack speed corruption!


Helm
As the helm I chose the Frostferno helm as it gives +4 gem levels to Elemental Hit and has the buikd in Cold to Fire Gem. It is comparable to a 5.5-Link dps wise but offers the possibility to use a different body armour to get more life.
Additionally it can be corrupted to get one or two +2 gem levels for Elemental Hit, making it a 6.5-Link dps wise, but those are really expensive!


Body armour
As we do not need 5 or 6 Links for our dps setup, we can use kaoms heart to get the +500 life, and some damage aswell.


Rings
While the Call of the Brotherhood rings is still use, we can swap out the Pyre ring (due to the Cold to Fire in Frostferno). Just go for a rare ring with life, resistances and wed - whatever you need!


Amulet
I have to say that I did not test most of these options...
The highest dps option, according to PoB, is Xophs Blood. It covers the enemy in ash, penetrates res and has avatar on fire which allows us to respec the tree a little and pick up more damage or life.
Another option is Yoke of Suffering. It allows fire damage to shock and increased damage taken on enemies.
Impresence with Flammability is also a solid option, as we do not have a curse in our gem setup.
I am currently using a rare amulet with life, wed and a little res. It works aswell.


Gloves
For the Gloves we still choose Tombfists. You can go for two abyssal sockets or a good corruption like curse on hit, attack speed or life. I would prioritize a curse on hit (like temp chains or enfeeble) over a second socket. If you have the currency, go for both.


Boots
Since we have sufficient damage and need some more survivalbility, the choice is (once again) Kaoms Roots. As the corruptions on Boots are not very convincing in 3.3, I enchanted mine in the Lab with Crit-Chance if you haven't crit recently to proc Elemental Overload more often.


Belt
As in the Budget-version, go for a rare belt with life, resistances and weapon elemental damage. If affordable, you can go for a Stygian Vise...but in my opinion the stats are more important than the socket (in most cases).


Jewels
As in the budget version, use two combat focus jewels to force the fire damage on Elemental Hit. Additionaly, to give us some more dex I used a Fluid Motion jewel to convert some strenght to dexterity in the templar area. It makes gearing just much easier.
The rest are rare jewels as in the budget version.

As the flasks are not different in the different versions of the build, I'll just note them separately.
The flasks are mostly up to your choice. There are only few dps increasing flasks, the other flasks are for survivalbility.

1. Bleed immunelife flask
2. Ignite immune Silver flask
3. Curse immune Sulphur flask
4. Wise Oak
5. Freeze immune Basalt flask
