The witch hut is a bit tricky to stumble into by accident. It involves using the Curse.
The kraken involves shipwrecks. It’s probably best to hunt for that on the archipelago map.
I’m happy to out right tell you either one if you want!
Figured out witch hut! Only kraken is left.
Got kraken! I'm not sure how though so I would appreciate the explanation for that.
Oh shoot! It looks like I forgot to actually add that in as actual rules text in the Journal.
The Kraken will be added to your hand every five shipwrecks that are created.
