From your inaros post, do the blue archon shards boost the base amount of health? because damn id like some stats
When the shards and their stats were announced, I believe it was Brozime who asked precisely that and Pablo answered saying that it'd be a little too broken if they let them affect base stats and be affected by mods. So, every Tauforged you get will increase your max health by 225, to a total of 1 125 extra health regardless of mods or Warframe.
You may find it disappointing, but the Arsenal screen says I have 11 699 health, instead of the 13 878 on the post, but that's because the Elemental Ward I gave him provides an extra 2 035 and Hirudo gives 144 to cap it off. You can call this cheating, but I do use that on his loadout, alongside a Rivened Furis (my favorite weapon in the game for a long time) to heal on command.
Here's the build I use. Even knowing its inner workings, it's still a marvel to show up and just not die, regardless of damage, while being immune to status (and, therefore, self stagger) and taking 90% reduced damage after armor.
According to the Wiki, this will net me around 54 725 effective health before adaptation. That's a 547 255 total EHP with Adaptation factored in, if my math is correct.
This build is obviously just meant to tank without worrying about casting abilities or dying at all. Of course, if you manage to somehow die with this thing and don't have a teammate to help out, you're dead, because DE won't let you Last Gasp as Inaros or Sevagoth. Regardless, it's just funny to me that you can stack it that high and just never think about it again.
Welp, I hope this overly long explanation that took me way too long to write and research for the exact values and equations helps!
