Titamat’s moving cube

A magical block of metal  springs into existence at a point you choose within range. The block is a 15 foot cube. You must summon the cube into an area of unoccupied space when you cast this spell roll 1d4+1 this will determine how many spell can be reflected in a different direction. 

Reflective aura - when you cast this spell roll 1d4+1 to determine how many times the cube can redirect any incoming spell, if a spell is casted within 5 ft of the cube it is redirected  in a random direction same for if a creature is targeted with a spell with in 5 ft of the cube. When the cube runs out of charges the spell ends.

Moving - as a bonus action you may move the cube 15 feet to an unoccupied space
