item Question

Hello diablo 2 community I was wondering over these years why these items such as arreats face,Herald of zakarum,oculus,Jalala mane,homoculus, bartucs claw and titans revenge have same character lvl 42 requirement.

Maybe cuz these items are sisters and brothers? Whats from your point of view comment down in the post bellow.

 

No brothers and sisters.42 lvl items are just half stage lvling to 99 lvl,and both items helps u a lot in next game difficulty(i mean nm-hell)
