As the Prince you main advantage is that you can not be lynched. This however does mean that you necessarily should let yourself be lynched since that will mean the town will miss a day of lynchings that should ideally be used on a werewolf. As with every blue power role you can think of outing yourself either early to avoid getting lynched on mid to late game when the town wants to know who can be relied upon in the hunt for the last werewolves. As always outing yourself van attracts the werewolves and make you a target but perhaps lesser so for the prince that for blue power roles with more active abilities. Last and not least at all, but actually more first and foremost remember to be awesome and flamboyant. You are the Prince after all. Long epic speeches are especially encouraged.
