This page will offer a guide on where to locate and how to complete the mystery, Comb of Champions, in Rygjafylke.
Find Bil’s Comb
Bil can be found on the shore of a pool southeast of Adrift Refuge and southwest of Hildesvini’s Crag. When you have found her, speak to her and she will ask you to retrieve her comb.
The comb can be found at the bottom of the pool she is sitting near. The water is icy and the pool is deep so you’ll need to be quick getting to the very bottom of the water to retrieve the comb. To grab the comb, you’ll need to press ‘E’ to interact with it. It is likely you will take a little cold damage from being in the water for a rather extended amount of time but as long as you have enough health, you shouldn’t have too much trouble with the iciness of the water. Make sure to be as quick as you can so you don’t also run out of breath!
When you reach the surface of the water, speak to Bil again to tell her you’ve found her comb. At this point, you’ll have completed the Mystery and earned some EXP, but afterwards you’ll also have the opportunity to walk with her and speak to her a little more.
