Distinct Spell Reactions

RabbeinuTam

All spells make the same reaction once cast: a jet of light comes out of the wand and spins in a circle for a second or 3 before it is deemed successful or not.

Would be really cool if each spell produced that which it is trying to accomplish, to mention a few:

Augumenti- (no light) a stream of water that douses the fire

Arresto Momentum- (no light) a see through net that stops the pixies etc.

Bombarda- (no light) small explosion

Expecto Patronum- Silver shield (or the shape of an unidentified beast- or an achievement can grant a selection of beasts to choose from)

Incendio- red and orange swirling flames

Protego- a clear expanding shield
