Shield 5 is already a projectiles defense, no need for another one.
Here is my take on this concept:
shield 1- Bouncing shield, 900 range bounce off 3 target grant might on each bounce
shield 2- Symbol of avenging, 600 range charge at target create a symbol that grant stability.
shield 3- Final justice, like the revenant sword 3 a 7 hit combo attack ended with a knock down, 120 range.
Reaper was base on Jason Voorhees, so its ok for this to base on a Marvel character.
