[3.23] UYNURUIL'S TECTONIC SLAM OF CATACLYSM with TOTEMS? [400M DMG] [200K EHP] | Juggernaut

i now have been playing the build since league start and i have all mandatory items as in the build guide. there is one problem tho, despite having a skill tree favored towards being tankier and better pathing for split personality, the tankiness of this build is nonexistent.
pob tells me that my max phys is 37,7k at a 7k hp pool. i dont understand how OP describes this build as tanky.
the second problem that i face is that the totems die very fast, sometimes before they could even attack enemies due to the delay.
