Raging Mage Slayer

You have practiced techniques in focusing your raging energy to block magic, gaining the following benefits while you are raging:

• You can use a bonus action to exude an aura of anti magic. The aura lasts until the start of your next turn.
• While the aura is active, magical attacks against you are made at disadvantage and you have advantage on saving throws against spells and magical effects. 
• While the aura is active, if you succeed on a saving throw against a spell or magical effect, you take no damage instead of half damage.
• When a creature you can see or hear casts a spell, you can use your reaction to move up to your speed to a space closer to the creature. This movement does not provoke attacks of opportunity.
