Combination Discipline
From the White Wolf Wiki, the most complete White Wolf reference
Combination Disciplines are unique vampiric effect which draw on the knowledge and abilities of multiple Disciplines. Combination Disciplines require a particular level of proficiency for each Discipline used, and the resulting effect often resembles a combination of the powers required. Some, however, are entirely distinct effects which draw on the themes of the Disciplines used, though these are often quite specific in their application.
Combination Disciplines are popular because they can add versatility to the Disciplines a character possesses or address unique situations. They are also one of the few ways vampires of higher generations can learn non-standard Discipline powers, as it is possible to create or learn Combination Disciplines that only require mid-level powers. That being said, Combination Disciplines are rare; they can usually only be learned from a Kindred who already knows the desired power, and are often jealously guarded secrets. Most are known to specific clans or bloodlines, and combine the in-clan Disciplines known to those groups, though there are powers shared by each sect as well.
[edit] Version Differences
Combination Disciplines were introduced in the Revised Edition of Vampire: The Masquerade and are mainly presented in the various Revised clanbooks and in the Advanced Disciplines sections of the Sect books. Many were consolidated and reprinted for the Dark Ages: Vampire books Players Guide to High Clans and Players Guide to Low Clans in addition to a few new powers. The only overall difference between Combination Powers in the two lines is that Dark Ages: Vampire established a standard experience cost of 7 * highest Discipline level.
The concept of Devotions in Vampire: The Requiem is essentially the same as Combined Disciplines.
