You have to ensure its not a minion, unique, champion or superunique
And its a demon
And you've damaged it below max health, and it hasn't regenerated to full
you dont have to consome your demon it will get replaced you cant bind normal demon from elite pack
thank you guys, i think the elite pack and minion is a reason,, but is there a urdar that is not minion? if it is minion, how many hard point do i need?
