Is it possible to be invincible without losing combat effectivness?

Here's a build I made: https://underrail.info/build/?HgsDAwoIBwQAwqAAAAAAAABpZAAAwqDCoChzwqAAAAAAAMKgeF8IRDvDnRXDnybDoR_DnmNVYsKyccKn4p-iA-KrhgXiv4cF4r-aAt-8

At 20% (236 without armor/juggernaut) hp it will have resists:
Mechanical: 62% (15 from heavy metal, 17 from conditioning, 30 from stoicism)
Heat: 47% (17 from conditioning, 30 from stoicism)
Cold: 47% (17 from conditioning, 30 from stoicism)
Electricity: 60% (30 from tempered and 30 from stoicism)
Everything else is 30% from stoicism

With Aegis, Morphine and Nervosomnifer:
Mechanical: 187%
Heat: 172%
Cold: 172%
Electricity: 185%
Everything else is 155%

Also food can give from 5% to 35% resistance to 1 element, and Parafibrotic Regenerative Injection gives 15% to mechanical and heat.

I don't know what is max resist but I assume it's 95% like armor penalty. So at 20% (236) hp without armor you can survive up to 4720 damage with meds.
Without meds:
621 of mechanial damage
445 of cold and heat damage
590 of electrical damage
337 of every other damage

With heavy armor and juggernaut these numbers will be even higher.

Morphine and nervo don't stack; nervo is just a better version of morphine like a super health hypo is a better version of an advanced hypo. 

Mech resist from armor can go to 95%, for other damage types it goes to 100%.  Reduction is 90% for mech and 100% for everything else.
