Do not start RF at level 1
Level the Marauder with a sensible melee skill first, later using Sunder for example. Righteous Fire is available early, but being able to equip the gem does not mean you can sustain its self-burn. Check fire resistance, maximum fire resistance and regeneration together before switching.
Safe switch test in a harmless area: activate RF and stand still. Life must remain stable or recover without a life flask. Then test a small fight. If life steadily falls, return to the levelling skill and fix resistance/recovery first. The actual switch level depends on your equipment.
Check RF self-damage concretely
Before mitigation, RF burns 90% of maximum life and an additional 70% of maximum energy shield per second as fire damage. In a life-only example with no energy shield or other modifiers: 75% fire resistance leaves 22.5% of maximum life per second; 85% leaves 13.5%. This illustrates the calculation, not a complete character plan. Regeneration must cover actual loss and leave room for enemy damage.
Ordinary fire resistance above your current maximum does not reduce this loss further. Raising maximum fire resistance changes that cap. Tasalio’s protection from ignite does not prevent RF’s own burning: RF self-damage is not an ignite inflicted by a hit.
Set up gem access and Lifetap correctly
| Component | Access / check |
|---|---|
| Righteous Fire | From level 16; Marauder buys the gem from Yeena after The Root of the Problem. Pass the sustain check before leaving it active. |
| Fire Trap | The gem requires at least level 12, dexterity and intelligence. Marauder does not simply receive it as his own Act 1 reward: without trading, use Siosa after A Fixture of Fate; Lilly provides another access point in Act 6. |
| Lifetap | RF’s continuous self-damage does not pay upfront skill costs and does not activate Lifetap. To maintain it, for example link Fire Trap to its own Lifetap and actually spend life on those throws. Check the buff icon; a cheap movement link with a low-level Lifetap can be a deliberately planned alternative. |
| Life upkeep | Lifetap makes supported skills cost life. Do not add it without life reserves and recovery. An RF link alone does not generate the buff. |
Gems and controls
| Role | Gems | Use |
|---|---|---|
| Clearing | Righteous Fire → Burning Damage → Elemental Focus → Lifetap | Move around enemies and let damage over time work. Add supports gradually; Elemental Focus prevents ailments from supported hits, but RF’s burning aura is not an ignite. |
| Boss | Fire Trap → Trap and Mine Damage → Burning Damage → Lifetap | Throw traps during safe damage windows and keep burning ground on the boss. Watch attribute requirements and life costs. |
| Defence | Purity of Fire; Vitality or Determination as needed | Choose reservation around your sustain problem. Blindly copying a fully reserved endgame setup can worsen the starter. |
| Movement/curse | Shield Charge or Flame Dash; Flammability | Choose movement for your equipment. Apply the curse to tough targets; telegraphs remain dangerous with RF active. |
What actually scales RF
RF scales through appropriate fire, area and damage-over-time modifiers and its underlying life/energy-shield contribution. Generic spell damage is not a universal multiplier for the RF aura. Fire Trap has different components and needs separate consideration. For a starter, plan life rather than a complicated energy-shield hybrid.
Passive priority: life and regeneration → reliable fire defence → appropriate fire/DoT clusters. Chieftain options such as Tasalio/Valako support resistance planning; Hinekora improves clearing through explosions. The actual order must pass the sustain test.
Upgrade and troubleshooting list
- Prioritise rare gear with life, fire resistance and regeneration. Meet off-attribute requirements for Fire Trap supports and utility gems. More maximum life can also change absolute self-burn.
- If life falls after a gear swap, immediately check resistance, active auras and regeneration. A higher tooltip damage number does not automatically mean a better character.
- Skip no-regeneration maps and other modifiers your recovery cannot handle. RF is comfortable for clearing but does not let you ignore boss mechanics.
