How ti determined if opponent is a cheater do those have 100k hp in pvp are cheater’s?
Nope. It’s not much about power, hp and whatever. It’s more about eternal gears. Eternal gears can only have a specific set of affixes (which you can see on codex). If you see any eternal gear with a different affix it’s supposed to have, it’s very likely to be a cheater.
luis is right . you can check the codex for all items info.
