The Queen of the Aldmeri Dominion during the Molag Bal crisis was capable of creating magical shields which incinerated phisical projectiles. In her specific case, Daedric arrows. Magicka count is a game dynamic representing the power of a mage, so it is possible for a magician to have very high Magicka. As for teleporting, both the Sload and a majority of mages in the second era were clearly capable of creating portals from place to place. The Sload are the best example as they literally reply on teleportation and levitation magick to get around. And what else am I supposed to call a magical shield? Because "magical shield" is tedious to type on a tiny phone keyboard.
