Images  on  phone  say  too  large  to  uplaod .    Sent  them  to  support  though.    Any  history  of  others  hotting  this.    Read  aome  theads  but  alwja seems  to  be  something  overlooked  by  player.    Number  of  ser  pieces  ,  artifact  level,  etc

99.9% you are reading the challenge incorrectly and doing something wrong

Honestlt  thanks.    Read  ot  again  and  it  was  3  sets.    I  had  3  of  the  6  heroes  with  4  ser  instead  of  3  2set  artifacts.    Thank  you  for  the   reaponse !
