SUPERLATIVES!! 11, 15, 24, andddd 50!
11. ...is the biggest flirt, or has had the most romantic stuff going on?
Biggest flirt is definitely Halla. Will hit on anything hot and mildly intelligent. Sammy's a close second. As for most romance going on? In an actual campaign, probably either Noa, who fell in love with the daughter of a tribal chief after saving her soul from being trapped in an inanimate object, or Daga, who had a sweet budding mututal-crush thing with Mirik, a lizardfolk cleric in the party, until Mirik sacrificed himself to ensure the death of someone who would have handily killed the entire party, thus plunging Daga into grief, depression, and rage. I think Noa wins.
Dring. They often don't see the point. People will find out anyway. They grew up in a large, close family unit of kenku where anything overheard could be perfectly repeated, so someone always found out your secrets. But also they don't like lying all that much. They're just a very honest bird.
24. ...would win a battle royale with all the others?
OH JEEZ. Honestly? Probably Sammy. Assuming level 20, Sammy's resistant to all damage but psychic while raging (double-resistance to fire damage), and also, uh, they're kind of the favorite of a goddess. A minor goddess, certainly, but she's very much still a fuckin' deity, and she loves her Samsam.
50. ...is or was your favorite to play in combat?
HMMM. Toss-up: either Daga or Cohr. Daga because they did all their attacks singing, and Cohr because as a knowledge cleric they were pretty fucking versatile. Only thing they couldn't really do was stealth.
