Once you forma it resets your Weapon's (or Warframe's) rank. It basically makes it the way it was when you first got that item, except it will have the new polarity you selected. Ranking up the item is the same as the first time, excpet you don't gain MASTERY points. You can still level it up, but you won't get mastery. Formas are meant for when you have a weapon that you just LOVE and want to make it better.
