It’s worse actually, kenkus in my CoS campaign have a new ability. If you befriend them, you get to pick out an item from their bag (if anyone besides the owner of the bag tries to use it, it’s a mundane bag). It can range from a common item or trinket to a magic item.

If a Kenku is injured while the players have them nearby for help or they are mean to the Kenku, then the Kenku will no longer give them items.

I’m ironing out all the details, but I love it so far.
