Auromancy

Auromancy is the creation, control, and manipulation of magical fields, or 'auras'. Its practitioners are called Auromancers. At least some degree of auromancy is considered a requirement for any healer.

A particularly-skilled auromancer can even produce an Anti-Magic Aura, an aura capable of absorbing any form of magical energy. This ability was highly sought-after during the Mage Wars.
