Looking For Advice For Improvements On My Pyroblast Miner

Thank You In Advance For Investing Your Time Here
To Start Off I Am Very Happy With The Build
1. I Never Done Red Maps Before Cause I Would Simply Die And Had No Damage
2. I Got Like 12 Exalts To Spend And Am Very Comfortable Making Money
3. Im On Xbox Consoles

My Problem : I Hit A Wall On Red Maps Specifically The Highest Level Maps 14+ Cause I Just Die Randomly Out Of No Where
Reasons That I Recognized:
Corpse Explosion
Opening A Door And Getting Hit By Range Projectiles Or Spells
Flame Dashing Into A Group Then Dying
Getting Stun Then Dying
I Havent Died Yet To Freeze Status
Theres Some Bosses That I Would Like To Overcome Cause They Are Too Hard To Kill
Core And Lava Lake Map Bosses - Basically Act 9 And 10 Bosses

I Currently Do Not Believe Chaos Resist Has Anything To Do With My Dying
When I Have The Chaos Debuff I Just Flask - I Know It Sounds Bad And Nooby But Im being Honest
I Had To Switch To Chaos Resist Gear Once For A Rogue Exile Unique That Had Blue Fireballs

OK I Cover My Problems That I Want To Cover - Survivability

My Current Idea Is To Buy Kaoms Heart Or Belly Of The Beast For Life ??? I Could Buy That Unique Staff Pledge Of Judgement For 100% More Mana With Mind Over Matter

Honestly I Got 3 Jewel Slots to Fill With Life / Mine Dmg / Mine Throw Soeed

I Tried Going CI Or ES But Failed Too Hard To Get Gear

Plz Help Me Out Im Kinda Not Clever With It Comes To PoE
My Character Is Mine_One_Shotter - Thank You Once Again
