At first you will only be able to apply a small amount of magic through your works, creating minor effects like illusions or emotional stimulation in those who are near the work of Art. But with time and with special material and mystical perpetrations you can imbue an incredible amount of magic into your works, which would put a whole city into a dreamscape, or turn a small back yard garden into a backyard jungle that slowly consumes the town.
You have the ability to create a wide variety of artistic mediums, gaining the knowledge of how to create any kind mundane artistic medium, the infusion of materials can take many forms based on your personal style of magic, but compounding infused materials with other infused materials increases the infused magic amount multiplicatively.
You can create a wide variety of hand crafted artistic works that create magical effects based on the intent and design of the work of Art. With enough practice and experimentation you could achieve a wide range of effects as long as they are all centered on the work of art itself. It's strengths lay in area effects and requires a skilled artist to create complex functions or conditions within the works of art, working at its peak when indiscriminate in effect, as the painter you can choose to be completely immune from the effects of your creations.
