This is the latest version of Abel traveling priest outfit. The original author Sunao Yoshida passed away shortly after this outfit design, by Thores Shibamoto, came out. So, his story portion accompanied by this outfit design of Abel is very short, and this comes in after the coronation of Esther as Queen of Albion in the story timeline.
Main difference between this one and the former Abel's outfits are simply the length of the cape, shapes of arrows, design of the left hand side armor, more gold in color.
