Extracted from Trinity Core Source (SharedDefines.h). Last full extract 11/20/19. Reformatted and several updates from source in 2022-2023.

Please note that while many Spell Headers may contain different wording from various sources (largely dependent on sources/forks) and years of work, the goal is to convey information most accurately and understandably. Only when programming or creating complex modifications would the header information be needed (which can be found in the most recent or current version of the project you are working in.)

This is an ongoing update of many important integral attributes that define spells and abilities. If you have knowledge of these please feel free to add any missing information, especially ones from Cataclysm forward. --Xiberion (talk) 16:43, 10 May 2023 (CEST)
