Cultivation is a passive racial skill known by all tauren, granting them 15 extra points in Herbalism. It has no effect if the character does not have Herbalism as one of their two primary professions. The bonus is a flat +15 regardless of the character's Herbalism skill, meaning that tauren herbalists start at 16 (1+15) skill when they learn the profession, and can reach a maximum of +15 over the current cap.
