Dear Crows, let me give you a quick overview on the BATTLE Domain of Crowfall and which Major and Minor Disciplines they give you access to. If you want to check out what each Specialization Class brings to the table check out my Races and Classes Guide.
CREDIT: I want to thank Tinnis, who made an invaluable contribution by providing the descriptions of the disciplines I could copy paste as captions to you can search the disciplines and their abilities.
