The phys mitigation is shown for a phys hit of 22000, which is a crit shaper slam. I don't think many things do more damage in a single hit, so I think that is a realistic showcase of how much % phys reduction you are getting from your armor (rather than 50k armor giving you 90% flat phys reduction in tooltip since it expects enemies to do 500 damage to you).
Since the last video, I swapped flesh & stone for dread banner and also added skitterbots + bonechill (thanks /u/terracide99 for the suggestion). I then slotted in disorienting display to still have blind. Adding two auras made me need some more mana reservation, so I had to swap some es jewels for mana reservation jewels (don't have budget for es mana reservation jewels). I also swapped my watchers eye for one with discipline es on hit, phasing, and bleed immunity which I got for 8 ex. That lets me drop my corrupted blood immunity. Awakened fork cost me 2 ex. Tbh, I forgot how insanely good awakened fork is with spark; while technically, each spark still hits 4 additional targets at max, awakened fork increases the probability of spark actually hitting something by quite a lot due to creating more spark projectiles and sending them out at an angle from where they hit the enemy.
You can see Kosis does chunk me quite a bit; was my mistake using VMS instead of MS, as VMS is pretty bad at burst mitigation (only can take half as much damage from each shot as MS). I really think they should change it, as currently, VMS is usually weaker than normal MS, which feels kind of stupid.
