Cas ended up as paladin. He is warrior of god afterall, which was kinda modus operandi for actual middle ages paladins
or to be accurate term paladin means archetypal ideal knight not actual person (mostly) but whatever.
Since it’s fantasy game I let myself to make this outfit strategically stupid for aesthetics sake. Starting with lack of helmet for obvious reasons (let’s say his halo is magical or something XD).
Left arm is unarmored because he holds shield anyway. That would destroy his flight ballance but hey. If angels could fly without having actual tail then that should be only minor inconvenience.
Speaking of inconveniences. That chain mail should be long down to his ankles. Wing covers of course should be taken off if he’d like attempt to fly but besides that imho they are best solution. There is no point in covering feathers that are dead tissue anyway and will regrow eventually. Besides they look fancy and make me think about hussars (even though their wings are more of a myth) in a way and they were badass.
