It has had many variations ranging from Occultist to low life Guardians, Hybrid Inquisitors & now I bring you the Juggernaut. Righteous Fire has been in Path of Exile since Closed Beta. Juggernaut also excels in SSF unlike the Inquisitor, however, if you’re looking for the more complex inquisitor RF build you can find that here Juggernauts Mitigation is unrivalled making it extremely hard to get one hit with this build. This will even end up protecting you against Elemental Damage. Also, no need for anything complex this build is great for first timers since your main defensive layers come from Armour stacking. Juggernaut has a much easier time getting the defensive layers online. However, The juggernaut can easily hold his own.
Is a bit more expensive and complex to build for players looking for something a bit more advanced due to ES scaling and is nearly permanently curse immune. He goes Block based to reach 75% Block & Spell Block which ends up shrugging off most little hits. The Inquisitor version has more boss damage.
Before you read on, I also have an Inquisitor version of Righteous Fire.
