Devotion

From the White Wolf Wiki, the most complete White Wolf reference

Devotions are specific vampiric powers which draw on the knowledge and abilities of multiple Disciplines.

Devotions are difficult to learn and must generally be taught by a Kindred who has already mastered the Devotions sought. They are generally of limited utility and designed for specific circumstances, and shared only among trusted groups - most often between members of a bloodline or Covenant, though unaligned Kindred may also know Devotions specific to their lifestyles and may teach them to others in similar situations.
