The Undying Flame Ghost of Tsushima Tale

1. Find the musician in Jogaku / Light the campfire

Find the musician and light the fire by which he sits. He will then tell you another tale, this time about a fighting technique called the Way of the Flame.

2. Ascend Mt. Jogaku

Your goal is to reach the top of Mount Jogaku. The difficulty will be the fact that it is very cold around the mountain and you will slowly freeze there. In order to reach the summit safely you have to follow the path marked by successive bonfires where you can warm up. You have to move quickly from campfire to campfire until you reach the top.

The first campfire (Campfire #1) is located on the rocks north-east of the camp where the musician sits.

To get to the second campfire (Campfire #2), go over the bridge to the other side, kill two wolves you run into there and climb up to the rocks where the campfire is from the left side.

The next campfire (Campfire #3) is located to the south-east. On the way to it you will come across one wolf. When you kill him, you will have to use the grappling hook to jump across the gorge and then climb some rocks.

There are four wolves on the path to the next campfire (Campfire #4), which is located to the north and slightly to the east. It is best to kill them using a bow while standing near the campfire and only after you get rid of them move towards the next campfire. A ronin, which the musician mentioned to you, will be sitting by this campfire. You can talk to him.

The road to the next campfire (Campfire #5) will be relatively long. First run north, then to the right.

When you see the fallen tree trunk, climb the rocks on the left and then step on the fallen tree trunk.

Then use the grappling hook to get to the rocks where the next campfire is located.

The fire will be extinguished so you will have to quickly light it.

The road to the next campfire (Campfire #6) will also be relatively long and complicated. First run straight ahead.

Then follow the line stretched between the rocks.

Jump on a branch and move to the rock ledge above.

Use the grappling hook to get to the top of the rock on the opposite side.

Use the grappling hook again twice to get further.

You will land right next to the campfire that is extinguished so ignite it.

Now you have the last part of the route to the top of the mountain to pass.

Go ahead and approach the tree stump sticking out of the rocks.

Use the grappling hook to get to the protruding rocks on the other side of the stump.

Watching out for a bear, climb up the to the top and jump over the gap to the right side.

A few steps further you should reach the steps leading to the dojo standing on the top of the mountain. When you get there, you will no longer have to worry about the low temperature.

3. Investigate the dojo

Approach the building and you will meet a man who will introduce himself as Bettomaru. After a short conversation he will agree to teach you the Way of the Flame.

4. Pick up the rock

First, pick up the rock lying near the arena.

5. Duel Bettomaru

Enter the arena and start a duel. At some point during the fight, you will be prompted to ignite your sword. Do it and defeat Bettomaru using a burning sword.

Of course, you won't kill Bettomaru. You will thank him for passing on his knowledge and promise to use your newly acquired skills against the enemies of Tsushima.

6. Descend Mt. Jogaku

After the duel is over, descend Mt. Jogaku by using the R2 prompt on the steps leading down...

...or by a wooden pole staked into the ground near the arena.

7. Return to the musician

To complete this quest, go back to the musician and talk to him.

One of the rewards you will receive will be a new skin for yor sword - Izanami's Grief.

Another reward you can get after completing this tale is a new mask - Purity of War.

Note: This may be the reward for completing all mythical tales. I'm not sure because this was my last mythical tale.
