immortality spells

tarkhan bey

Help me out guys,I may be missing something but there is no basic immortality spell.Now I do realize that there is nothing remotely basic about immortality but if this style of magic is taken as a new sorcery style does the character forego the right to a spell and have to wait until he gets another advanced spell pick? What if at the same level he gets both new sorcery style and advanced spell options?
