Welcome to this End-Game World of Warcraft Blood Death Knight Class Guide. It is simplified and streamlined to be straight-to-the-point. It's intended for players who want to excel at tanking without having to dig through colossal walls of text.
For highly competitive raiders and high parse chasers, it's best to explicitly use simulation tools, spreadsheets, and your own judgement instead of static guides. Your current gear setup, raid needs, and playstyle preference must be taken into account to produce the optimal stat weights, talent builds, and ability prioritizations necessary for your goals.
