levitate
jump
fly (the player cannot stay still, and controls now resemble a plane with swords and magic)
sky should be dangerous with dragons,whatever skyrim has to replace the cliffracer,people with bows, winged daedra etc
water...
swift swiming should be ingame. how else would you escape the sea serpents and water dragons bethesda has for us? the player should also be able to use this ability to jump out of the water like a dolphin
water walking- i want to walk across the waves! monsters should be able to attack you from under the water and destroy you like a killer whale kills a seal.
ice moving- frozen lakes that you can move through as if they were water- lore correct, skyrim's vampires are supposed to have this ability.
water should be seriously dangerous with dreugh,water dragons, sea serpents, various types of slaughterfish, prehistoric inspired fish and the ever so deadly MUDCRAB.
