Build explanation + 1 gorge run (vulnerability): https://www.youtube.com/watch?v=NHZO0amFuco
Another two gorge runs (Elemental reflection / 40% less regeneration): https://www.youtube.com/watch?v=753jsck9ov4
Sorry for heavy german accent, english not my native language^^

Since we use Avatar of Fire (AoF, http://pathofexile.gamepedia.com/Avatar_of_Fire), only 50% of physical damage will be converted to fire damage, the other 50% physical part of Blade Vortex will get lost. But there's a way to use the full damage of Blade Vortex by using certain rings and a certain gem:

If we do the maths:
50% physical to fire (AoF)
50% physical to lightning (Gem)

50% lightning to fire (AoF, means there is still 50% lightning damage unused because of AoF)
50% lightning to cold (Ring, Call of the Brotherhood)

100% cold to fire (Ring, Pyre)

--> full damage conversion, i.e. we do fire damage only!

For Righteous Fire I highly recommend this shield
Rise of the Phoenix is pretty standard for Righteous fire builds, because of the +8 to max fire resistance. It also helps a lot against reflect maps.

Must have:


Weapon: +2 to fire gems (for purity of fire) and spell/fire damage, cast speed also good (doesn't roll with daggers though)
For example:

Boots, Helmet, Chest, Gloves, Amulet and Belt:
any good rares with high life, armour and resis rolls. Later you can buy lightning coil to optimize your build, but it isn't really necessary. On some rares I highly recommend the +dexterity mod, since stacking dexterity through the skill tree can be a bit troublesome (you need at least 155 dex for a lvl 20 BV!). The life/mana leech on boots is optional, but not mandatory.
For example:

Flasks:

1 panic life flask is enough. Ruby flask and granite flasks are a must. Other ones can vary to personal preferences, for example Taste of Hate or Silver Flask.

Must have links:

Chest: Blade Vortex, Spell Echo, Physical to Lightning, Fire Penetration, Increased Duration, Elemental Focus (It's an order from 4l to 6l. Elemental Focus gives a huge boost since we do only fire damage. Added Fire damage is no option here.

Boots/Helmet/Gloves:
1. Righteous Fire, Elemental Focus, Increased Burning damage, Increased Area of Effect
2. Cast when damage taken (lvl 1), Curse on Hit (lvl 1), Ice nova (lvl 8, quality very good here!), Warlord's mark (lvl 20) - this CDWT setup is very important for survivability!

Weapon: Purity of fire (must have for righteous fire!)

Other must have Gems: Enduring cry (to keep charges and regen up), Blood rage, Hatred, Rallying cry

The remaining skill slots can be filled to you personal preferences, i like the CWDT + Molten Shell + Tempest shield on my RotP.

Ascendancy:
Bandits:

Till level 65 (because with Level 65 the fun begins, you can use the RotP shield): You can use any skill you like to use for leveling, there are no restrictions except the item requirements maybe. I recommend to take the +30 dex nodes, to make it easier until u have the gear. If you want to use BV early, get the +duration nodes near the scion start.



Level 80 (stacking life, respeccing +30 dex nodes, getting +duration if not done yet:


Level 92. I use the 'intuitive leap' jewel near the scion start to get the extra aoe nodes and to gain access to the +duration points, getting life and jewel sockets:
In the jewel sockets put jewels with mods like %increased fire damage, %increased AoE damage, %increased physical damage, %increased spell damage, %increased cast speed. Increased fire and AoE damage buff both Righteous fire and BV! I also use a 'fluid motion' jewel to stack dexterity.

Level 100: depending on gear either stacking last fire damage nodes (explosive Impact skill point), getting aura nodes or stacking mana. Depends on personal preferences, i think i would've gone on damage nodes, since mana and auras are no problem for me. Getting 20% increased aura effect (for +1 fire resists with an level 23 purity of fire skill gem) doesn't seem worth it, since you got to sacrifice a jewel spot as well.

Pros:
tanky, dpsy, fun to play, good clear speed, both physical and elemental reflect maps are no problem, also mods like vulnerability, slower regen and -max res are doable in most cases.

Cons:
works badly with maps with the 'no regeneration' mod, shock hurts a lot, medium AoE (but still good clear speed)

- 22,5 k * 10 seconds = 225k (rough calculation)
+Righteous fire damage, no tooltip dps since it's wrong. By rough estimation it should be around 25-30k. Most white mobs burn down by the fire only.
Also not to forget the 35% increased damage against burning monsters also the 47% fire penetration from the ascendancy and the skill gem (which could drop the monsters resistances below zero and makes resistant monsters easy to kill).
