PoE The Iron Fortress, Fire builds with custom stat filters

Hey everyone, I'm looking to build a high budget infernal blow character. I think berserker/marauder fits best, because we can include the chieftain explosions aswell. I made a strengthstacking template for the build, but I don't think I did a very good job. What suggestions could you guys give me to improve upon this? Btw doesnt have to be a strengthstacker, only requirement is it being able to fire explode very well. (also big numbers plx) Budget is about 2 mirrors pob:

Gear 22% AS/15% Chaos Pen Paradoxica with Great Crucible Tree - 20 Div Redblade Banner with 4% Max Chaos Res for Divine Flesh + 50 Life on Block + 15% Explicit Life Modifiers - 1 Div Double Elevated Warlord/Hunter Royal Burgonet with Molten Strike Enchant - 15 Div 30% Quality + 120 Strength Roll Iron Fortress with Strength per quality Enchant and White Sockets for Clear Swap - 8 Div 55 Strength + 78 Life + Perfect rolled Essence Attack Speed Gloves with some elemental res, Eldritch Implicits, and damage during flask effect craft - 5 D
