Ahhh, I was reading it that the Coat and Armor were 2 different pieces. Being that I'm squishy I could use the armor and the swarm bonus is an added bonus. I will update accordingly.
Understandable confusion. I realised when you asked that it did look like two different items when I wrote it up, lol!
Katsuye, please remove the lead artificer's ritual book from the group loot. Vendis had it last, and he is gone now... with the book.
Anyone checking in here?
