With regards to knowledge rolls, I usually have one PC make the roll and let other PCs help.  That gives them one attempt - and advantage on the roll.  However, I do not let someone help unless they have a reasonable basis to be able to contribute.  For example, a barbarian with Int 8 and no Int based skills that wants to help a wizard/rogue with a +16 to Arcane checks perform a DC30 arcana check is not going to be able to help.  However, if the wizard's arcane roll is to figure out an ancient magical puzzle, the fighter with a sage background and proficiency in history might be able to drum up some historical fact of use - and can offer his help.Too many rolls destoys role playing.  Too few mean that there is no chance of failure.  1 attempt with advantage gives you a nice window to control a reasonable chance to succeed while maintaining a chance of failure.  It is a nice balance.</blockquote>
