FAQ
Where is the shop in Queen's Domain?
The shop is Umbada's Trading Outpost. It opens after you beat the first boss, and you pay with Ancient Coins. Duck figurines you bring to Umbada and later boss kills add stock.
What should I buy from the shop?
Players point to three buys: the spare trident key after the Tower of Knowledge boss if you are stuck on the temple doors, accessories that cover a resistance you are struggling with, and the magic weapons that appear after you clear the tower.
What do duck figurines do?
Bring them to Umbada. They unlock more items in the shop, and giving him every figurine unlocks the achievement "A Fine Collection".
Where do I find Captain Aganmi's missing crew?
Four raiders are scattered around the island. One is on the starting beach, and one is somewhere you need a Travel Crystal Fragment to get back from. A Steam guide has screenshots of all four.
