Aqua Ring

At the 6th Level you can manipulate water to circle you, protecting you from harm. As a bonus action on your turn, you can spend 2 sorcery points to create this ring around you.. The ring moves with you and lasts until your next turn (no action required to dismiss it). 

While this ring protects you, you can use your reaction to interpose the water between yourself and your foes. When a creature hits you with a melee weapon attack, you can use your reaction to cause the water to absorb some of the blow. When you do so, the damage you take from the attack is reduced by 1d6 + your charisma modifier + half your sorcerer level.

If you reduce the damage to 0, you can push the creature up to 10 feet directly away from you and knock it prone.
