I have a strange bug... My party leveled up to level 6... and everyone was fine except for my player who had a Kenku Swarmkeeper Ranger. He finished the Charactermancer upgrade but then it just... doesn't do anything. So I thought it was an error on his end and I tried it... Nothing. I built a new ranger... Nothing... I built a new ranger in a different campaign... nothing. It's a mystery to me. See below for an example of a mock character... it stayed this way for 10 minutes before I pulled the plug.
