This guide will let you know how to do the Ice Cavern Mystery quest. First, you need to go into the ice cavern and talk to Elsa. After that, talk to Anna and then you need to take the green crest from Anna’s house.
It’s right near the clock, so pick it up from there.
Then you need to place it on the wall of the ice cavern.
After that, talk to Elsa and collect the bunch of items.
The first one is the pickled herring. You need to cook it.
For that, you just need some herring, lemon, onions, garlic, and some seasoning. It could be any type of seasoning. Then you will need the white passion lily. In collections, you can see where it is found by going into the foraging menu. It is found in frosted heights, so you need to go to the frosted heights find it, and pick it up.
The next thing you need to get is a carrot. You can easily grow carrots by picking up the seeds from the stall in the peaceful meadow and then a gold ingot. Gold is found in the sunlit plateau lots of it is found there and in a forgotten land. Once you get all the items, go ahead and put them on the pedestals and see what happens.
After that, talk to Elsa and a chest will appear and open up.
You’ll get a dress and then your quest will be completed.
