Picking up as many allies as you are able to will help you dominate the board. Every time you land on an ally tile you will be able to add another member to your team, the advantage of this is that you will be able to choose to roll your allies dice every time you roll. The dice each character has is unique to that character and offers different benefits and drawbacks. This means having several allies with you will enable you to roll the dice for each of them giving you the opportunity to get across the board quicker.
