Level 95 Holy Flame Totem Ascendant^3.20

Notes

Build from guiorioli, and thanks for  Tatiantel2 (www.twitch.tv/tatiantel2), the Shaper of Totems, for all the help with the build as well.

This build is based on the interaction between Scion's Chieftain and Hierophant ascendancies, giving her +1 Totem, a lot of fire damage and Life Leech from totems, which is quite unique.
It also takes advantage of Holy Flame Totem's skill description, which deals Physical Damage and converts to fire, so we can use some tricks to get extra damage.

How to use this POB:

 This POB got 4 different builds, depending on your needs:
  - Early mapping
  - Endgame - HCSSF w/o diadem
  - Endgame - HCSSF with diadem
  - Endgame - SC Trade

>>> To cycle between then, you need to change select the corresponding option in "ITEMS", "SKILL" and "TREE" tabs. <<<

Leveling Trees:

In "TREE" tab, you can find leveling trees.

Leveling gems:

In "SKILLS" tab, you'll find a session called "Leveling Gems". They are there to guide on how to level, but here are some more details:

The first thing you need is a Holy Flame Totem (HFT) and getting to level 4 to use it. 
If you are in SSF, you need to start a Witch and get past "The Mud Flats", come back using the waypoint, and you can buy HFT. 
 - This is very fast.
 - Get Flame Wall from quest reward, to give it to Scion.
 - While you are at it, you can keep Witch's Arcane Surge at level 1, and use Freezing Pulse to advance. You can buy your Scion a Freezing Pulse as well, to use until lvl 4.
 - You can also kill Hailrake in Tidal Island if you want an extra Quicksilver
If you are on trade, maybe you can ask someone instead.

Then, as soon as you kill Brutus, you can buy Added Fire Damage and Added Lightning Damage to link your HFT
You can also buy Clarity and Vitality

In Act 2, first quest you should do is killing Fidelitas (in The Chamber of Sins), so that you can get Wave of Conviction and Herald of Ash
This is a HUGE boost of DAMAGE.
Use Wave of Conviction as a self-cast until you get Ancestral Bond, and then, switch to Wave of Convictions Mines.

Then, you will be wanting to kill The Weaver (in The Weaver's Chamber, found at The Western Forest).
This will allow you to get Controlled Destruction (CD) and Elemental Focus (EF).

Once you get a 4-link, use HFT + Added Fire + CD + EF until you get Fire Penetration, then you swap EF for it.

In act 3, get Flammability. These are the skills you need to finish campaign. 
If you manage to get the mana for it, you can run Determination and Defiance banner, but isn't crucial for the leveling.

Explanations:

Arcane Surge
Hierophant ascendancy from Scion grants AS, but PoB doesn't take that into account, so I add it linked to a disabled skill.
Remember to link AS to either Flame Wall, Wave of Conviction, Flammability or Arcanist Brand while you don't have Hierophant ascendancy.

Exposure/Mines
Wave of Conviction applies -15% exposure. Before Ancestral Bond, use it as self-cast.
After you get Ancestral Bond, it deals no damage as self cast. This is why you link it to High-impact mine (which also gives some extra damage)
Then, we take advantage of Charged mines to have Frenzy charges, and of Combustion to apply more reductions to fire resistance.

Flame Wall
Holy Flame Totem fires projectiles which go through Flame Wall and get added fire damage.
Arcanist Brand is a nice way to grant that the enemy will always be inside a flame wall

Physical damage, Herald of Ash, Fire conversion
Holy Flame Totem deals Physical damage and converts 50% of it to fire. So, additions to both fire and physical damage works.
Herald of Ash adds damage based on physical damage, so it gets the entire Holy Flame damage (which is physical) and adds more. It's a huge boost in damage.
Finally, we convert all damage to fire through Avatar of Fire, so that all damage is boosted by increased fire damage

Auras, Mana, Diadem/Divine Blessing
This build stacks auras, so managing mana for the can be tricky. 
During leveling, all you need is Clarity, Vitality and Herald of Ash.
Determination is high priority for survivability, try to fit it ASAP. Defiance Banner also helps.
Devouring Diadem is a great source of damage by stackin one additional aura and freeing up mana nodes
When you have Eldritch Battery, you can reserve 100% of your mana and still use Energy shield to cast a temporary aura linked to Divine Blessing. 
(Be sure to keep Divine Blessing at level 1 and link it to Inspiration to make the aura cost less that the amount of ES you got)
Devouring Diadem is a quite target-farmable item, so it's an SSF option as well.

Ailments
We use Anointed Flesh nodes alongside with Brine King, a ring with 50% reduced ignite duration and Soul of Garukan
to have Freeze immune, 90% reduced shock, Ignite immune and 80% reduced chill. Pick last chill node from Anointed flesh to get 100% if you want.

Shaper Shield
A shield with Shaper influence is the only way to get 1 extra totem, being BIS for totem builds.
Ways to get it range from Expedition (Rog and Gwennen), Harvest (reroll influence) and shaper scarabs.
If you are in Trade leagues, you can usually buy a base for cheap and roll with influences, or buy a finished one.

Wand
It's easy to get +1 fire on act 1 wands, the ones you buy as soon as you get to town, at level 2.
A +1 wand -> aug -> regal -> craft cast speed is enough for the entire campaign.
If you don't get one, good increased spell + cast speed are good enough too
In endgame, I use Heathen wand because Profane wand requires too much Int.

Chieftain
Chieftain is a good ascendancy for HFT for the fire damage, str, covered in ash, and it's unique ability to let your totems life leech.

Hypothermia/Skitterbots
Skitterbots chill enemies, so Hypothermia works. Against bosses, which is when it matters, it has 100% uptime.
IF you don't like Hypothermia or don't want to invest into DEX, use Cruelty instead

Aditional Curse and Occultist in SC Trade build
Since there's the possibility of using Chieftain Flesh/Flame jewels, and they are usually cheap, this is a viable tech to get more damage.

Corrupted Blood Immune
The BIS is to have it in a jewel, corrupted implicit. Until you get a good one, you can use "Resistance and Ailment Protection mastery" instead.

Atziri's Step
Atziri's Step is a quite target-farmable unique with huge spell suppression, while still having the other two desired stats we need - life and move speed.

Physical to Elements conversion
Converting incomming physical damage to any element is a great defense against phys, since the damage will be mitgated by 76%
