.. Nattabloom over the pond

Use the all-seeing mask. You can see the hidden mushroom incline.

Switch back to the Mask of Invisibility.

In the area walk on top of the ledge. You can see the nattabloom.

I think those three mulch piles are the key.

Did you free the trapped älva, already?

Find three mushrooms and plant them and grow them to create a bridge to the nattabloom.

• One mushroom is in this area. ( Right after the bridge. )
• One mushroom is in the northern area, where you go by the mushroom "stairs". ( Go down the hole in the ground (can be seen with the mask) in the middle of the mushroom circle. Shrink the mushroom and dig it up with the trowel. )
• One mushroom is in the eastern area. ( After the bridge next to an älva house. )

Plant them and grow them. You have to plant them in correct order ( From left to right: large, medium, small. )

Use your dagger on the nattabloom.
