Crimson Mirror

You conjure from your own blood a mirror-like round surface floating perpendicular to the ground near you. A physical attack directed at you gets intercepted by this mirror, that catches the projectile stretching like an elastic surface, the mirror at this point loses consistency completely enveloping the projectile, which now becomes coated in a hard, dark red, glossy armor. the projectile can on subsequents turns be launched back at an enemy, they will have to pass a DEX save or get hit by the projectile with its original damage plus an additional 1d10 piercing damage. if they save they take no damage. 

 Details for higher levels:

 at higher levels you create an additional mirror that will block another projectile attack directed at you until the start of your next turn. IF used at level 6 you have the option to create just one larger mirror parallel to the ground to protect you against a (DEX save) area attack, again this works only for projectile attacks, for EXAMPLE: Catapult's shot, Conjure Barrage, Conjure volley, cordon of arrows, artillery shots. Instead it can't be used for non-physical attacks like Fireball, Lightning bolt or magic missile. The second part works as normal, the area of attack can be re-launched at within range (60 ft) with the same area of attack as the original attack with the same damage plus an additional 1d10 piercing damage as a DEX save. for EXAMPLE: conjure volley has an area of attack of 40 ft radius and 20 ft height, the same would apply to the reflected hit, the difference would be the additional damage and the range fixed at 60 ft (instead in this case of 150 ft)
