You imprint on your next spell your choice of special effect depending on the effect of the spell:

• Your face is imprinted on a cloud, smoke, flame or other material involved in the spell.
• A ranged missile leaves a trail of cloud that bears your signature in it's tracing.
• You can change the color of the flame on a fireball, lightning bolt to a color you identify with.
• You create a unique auditory effect.
• Your spell leaves behind a scent of your choice.
• You combine any of the above for anything within your own sensory range.

In addition to this spells effect, you can add a 1d8 roll to checks that involve performance. It does not affect deception or combat but can be used to add a personal touch in combination with all spells of the same type cast in the same turn. Similar to Thaumaturgy in timing but more vast in range and more suited to work with other spells.
