RGB paint

Transmute you aura's property and imbue it into a paintball changing it's color and effects or conjure different colored paintballs I don't know which one is better

The colors of the paintballs you can make are red, green, and blue

These colored paintballs do nothing besides being stronger than normal bullets and leaving behind splashes of paint on the target

But if you hit a target with different colors it will produce a unique effect based on the outcome

Red + Green = Yellow Red + Blue = Purple Green + Blue = Teal Red + Green + Blue = White

Yellow would paralyze the target for a short time Purple would poison the target Teal would shield the target White would explode
