Altar Imp Captain Summon Scroll from Black Spirit

I tried to summon it but it wont come out, it says requirement does not met. Is this a solo or a co-op?

This is the item in question I suppose, the first thing you need to check is whether you have unfinished quests with your BS (BlackSpirit) if you do then you have to finish it by receiving the quest reward before you are able to summon another, otherwise if you aren't the party leader you cannot summon, if you aren't level 45 yet you cannot summon, not sure if there are any other conditions.
Hope this helps
