Acastus Knight Porphyrion

The Acastus Knight Porphyrion is one of the most heavily armed and armoured chassis of Imperial Knight ever produced by Imperial technology, a design that essentially sacrifices the mobility valued by most Knights for greater firepower. Even at the height of the Great Crusade Acastus Knight Porphyrions were incredibly rare and only few Households were able to field Acastus armours. In the 40th Millennium, they are even rarer, ancient reminders of the Adeptus Mechanicus lost power and mastery.
