Immortality, you are immune from taking damage for a fixed amout of time, as for Friendship, if you press TAB and look at the scores, there is a section marked "wishes" because sometiems the admin will set a fixed amount of wishes, so people will use teamwork, and and when you make a wish, you get a wish point, friendship gives you a lil freebie wishpoint, so you just get an extra one allong with the wish you made :]
