1. Purchase a pair of Fractured Gloves. Ilvl 84 gives you the highest tier res, 85 gets you the highest % Life Regen roll. I'd go pure Armour — Titan or Vaal Gauntlets.
   • Desired Fractures 15%+ Increased Life Regeneration, 30+ Dexterity, 60+ Life, 20%+ Chaos Resistance
2. Purchase essences. You will have lots of variety here, but no matter which you end up picking I would recommend getting 20+ Screaming.
   • Screaming Essence of SorrowScreaming Essence of SorrowGuarantees dexterity on armour, cold penetration on weapons. — Dexterity, saves skill points on the tree
   • Screaming Essence of EnvyScreaming Essence of EnvyGuarantees a chaos modifier. Chaos resistance on armour, added chaos damage on weapons. — Chaos Resistance
   • Screaming Essence of GreedScreaming Essence of GreedGuarantees a life modifier. Increased life on armour, life regeneration on jewellery. — Life
3. Constantly use your essences until desired outcome.
4. Bench craft:
   • Life
   • Area of Effect & Damage
   • Damage during Flask Effect

This next step is very RNG based — you can get it on the first try or take over 100+.

5. Eldritch Influence — purchase Lesser Eldritch EmberLesser Eldritch EmberAdds a Lesser Searing Exarch implicit to a body armour, boots, gloves or helmet.s (60+) and use until you get Ignite Spread on your gloves. If you are using the Fan the Flames cluster you can go with Fire Damage over Time Multiplier.
   • Lesser IchorLesser Eldritch IchorAdds a Lesser Eater of Worlds implicit to a body armour, boots, gloves or helmet.s (20+) — roll till you get % Increased Damage per 100 Strength.
