Level 96 Vaal Righteous Fire Juggernaut^3.21

Notes

Guide:

To check the gems you need to have, go under the "Skills" tab and see what to get at certain levels.

The difference between Default and BEEF trees:

Default: More damage, less tough against hits, tougher against DOTs.
BEEF: Less damage, tougher against all hits, less tough against DOTs.
Spell damage does nothing for RF but improves Fire Trap, while elemental damage improves both.

Act 1

Dual wield 1h Sceptres early on as they increase your elemental damage and deal decent physical damage for Molten Strike.
Keep an eye out for a 3L (all red sockets) item. I found a nice 1h Sceptre sold by Targlieth that had 3L all red sockets. 
Focus on items that have Life and Resistances.
For boots use Wanderlust or any boots with Movement speed if possible, otherwise Life/Resists.

Act 2

Keep dual wielding Molten Strike and upgrading your weapons until you reach lvl 22.
At this point you should have Herald of Ash + Vitality(lvl1) as your auras.
Around lvl 22 you can start using RF if you have CAPPED FIRE RESISTANCE, Vitality, Springleaf and all of the Regen nodes on the passive tree taken by that point.
Life regeneration items like Kikazaru or just rares with life regen help a lot.

A good way of using RF and Searing Bond/Fire Trap together is by placing both of them inside tabula rasa and linking them with gems that benefit both.
RF + Searing Bond/Fire Trap + Elemental Focus + Efficacy + Combustion + Lifetap (Lifetap is optional, it does give more damage when you place a totem but costs a lot of life).

A good Elemental damage or +1 to all fire spell skill gems Sceptre will be optimal for leveling. (Check "Items" and find the "RF leveling" set)

Use Shield Charge + Leap Slam + Faster Attacks all linked together inside your weapon or your shield.

Act 3

Look for 4L items at this point and if you find one use an essence or an alch on it. Alternatively buy 1c rares from players.
Get Determination and replace Herald of Ash with it. Should be usable, if it isn't, wait for the mana reservation efficiency nodes.
At this point your Auras should be: Vitality (lvl1) + Determination + Purity of Fire.
Complete the Normal Lab before you fight Dominus. It should help quite a bit. Alternatively do it before Malachai in a4.
Swap out Combustion with Burning damage in your main Link setup. If you're not using Tabula Rasa check the "Skills" section and link the gems appropriately.



For Brutal restraint Jewel notables, look for:
1) Alchemist's Genius
2) Frenzy on Kill / Flask charges gained
3) Life / Damage / Resists 
4) Movement Speed / Dexterity (if you're missing some)

NOTE: If you get 2x Life nodes on your Brutal Restraint then just craft Alchemist genius on your belt with the Essence of Horror.
