Elemental Primer (Talent)

You gain permanent knowledge of two elements that you may use as a primer for elemental finishers: fire, water, earth, wind, lightning, light, or darkness. Whenever you damage a target with an elemental chaos spell you afflict that target with an Elemental Primer of the same element you used. The next source of elemental damage used on that target combines with the primer to create an Elemental Finisher based on the elements used.
