A wind wall shoots out from the caster's hand 15ft wide and can either be used as a physical barrier between you and an attacker (adding 2 to your AC if someone targets you through it) or it can be summoned in front of you (even if a target is there) and pushed up to 30 feet away hurting everything it passes through in between. The targets must succeed at a Dexterity save DC12 and on a successful save they will take half damage. This spell deals 1d6+4 slashing damage and pushes the target up to the range of the spell. 

When casted with a higher level spell slot the damage is increased by 1d6 and the range is increased by 5ft. (Every 3 levels the AC bonus from using it as a barrier goes up by 2)(Every 4 levels the width of the wall is increased by 10ft)

When using a material component that has a strong tie to strong force (Such as a large creature wings) you can add on a similar amount of damage onto the attack in force damage rather than slashing damage, the original damage still occurs just with this added on and the material component is eaten when using this bonus effect.
