Apparently Kenku in the Dark Sun setting have wings. Which to me makes me think that they were not under the same curse as Kenku in other settings, possibly because whatever deity that cursed them did not have access to Athas at the time, after the Grey sealed Athas off.
I am wondering if their mimicry trait should be changed as well, because I think that was also part of the curse put on Kenku in other settings.
I added Kenku to my campaign last session, the players encountered them as random nomadic traders, but I used mimicry instead of allowing them to talk as normal. One player had Speak with Animals ability from his Barbarian subclass, Kenku are technically humanoids, but because they speak more like birds I gave him advantage on persuasion rolls if he used his ability to communicate with the Kenku. It’s a little homebrew that seemed right in the situation. I was wondering though afterward if their speech is even affected by the curse, or if it is just a common trait that all Kenku have no matter the setting.
How would you do it?
