Damage/Effect
You recite the incantation protego and a shield of light appears around you. This can block most spells unless they say they can break protego like avada kedavra.
When you cast protego you gain +5 to AC until the end of round. If you are attacked by more than one spell then if the bonus AC actually blocked a spell then take away the bonus of AC.
Example: You block an attack with protego but another enemy attacks you with expelliarmus, the attack roll is 15 and you have a normal AC of 13 but an addition of +5, you then have an bonus AC of +3.
* - When you're targeted by a spell.
