Looking at IA: War Machines of the Adeptus Astartes, I only see that the Dark Angels and Codex Space Marines can take Contemptors, but everyone tells me that Blood Angels can take them as well. Additionally, I was given to believe that Furioso Contemptor Dreadnoughts were a thing, but I don't see any indication of them in the book. Can anyone direct me to the rules I'm looking for?
