You are new to the game and your more experienced friends are waiting for you to come join them. Run to the end of the very long pathway to meet up with them!

w1a

Tutorial
Change controls mapping in the settings!

A little ways through, enemies and loot will appear. Get rid of the former and collect the latter!

w1b

Your friend Saayu suddenly goes silent after hearing a noise in the place they're investigating. Clark and Wyzeman go after her, asking you to wait by the door whenever you get there.

w1c

Soon, you hear Clark telling you not to go there and Saayu yelling for help.

w1d

You finally arrive and you watch your friends' avatars disappear.

w1e

[2] Defeat all the monsters in the room.

Are they responsible for your friends' deaths? Time to get revenge!

2wa

In the midst of fighting, a stranger comes in. As you are about to be dealt a deadly hit, he saves you.

2wb

Somehow, the two of you make it through. The man starts asking you questions about yourself. He offers to travel together and introduces himself as Iori.

2wc

Tutorial
Consume crystals to recover your HP.
There is a set number of them available and will replenish when at a Safe Area or Terminal.

[3] Search for the exit.

Open the door and get out of the room. Keep going on the path until you reach the Waypoint.

3wa

Tutorial
Yellow diamonds seen in the mini-map and full map indicate Points of Interests. You can also create your own POIs on the map!
Battle Tip
Some moves require stamina or SP. Make sure to know which consumes what! Sword Skills use SP while using your shield and Crush Attacks use stamina! Keep an eye on your status with the bars on the upper left side of the screen.

Iori seems to doubt that the kobolds are what took your friends out. He understands if they were solo, but they were in a party, and considering how the two of you are doing just fine, it's a bit suspicious.

Battle Tip
You can bring 1 with you on each quest. They can die in battle but will automatically revive after a while. The process can be sped up by the player.

Parrying can lead to opening for Combo Skills!

A more forbidable enemy appears. Try doing combination skills with Iori to deal better damage. Take note of your Combo SP as you battle.

Rest at the Safe Area. Your health and crystals will be replenished, but monsters that have already been slain will also respawn. Press forward after resting.

[4] Defeat the Sentry Golem.

Take everything you've learned so far and practice it in fighting this boss-class foe! Don't forget to mind all your SPs and stamina. Doing a combo attack with Iori will deal massive damage! You can also use Iori for healing if needed.

4wa

After the battle, a girl will come in, screaming for help. She claims that a boss-class enemy is destroying her friends.

4wb

[5] Find the girl's party.

Move onwards through the area.

Go on until you reach the large door. There is a Safe Area before it where you can heal up if you need to.

5wb

Walk towards the girl at the end of the room.

5wc

She was a distraction! The pink-haired girl attacked us! They're Player-Killers!

5wd

Stella? Didn't Clark say her name before his avatar disappeared? Were they the ones got rid of your friends?!

5we

The girls cause some shaking to happen before they run for it. This isn't good...

5wf

[6] Defeat Illfang the Kobold Lord.

Yikes! They left you to deal with an boss-class enemy! Illfang holds a shield so you have to get rid of it to deal damage. Try Crush Attacks! Be careful of other kobolds joining the fray!

6wa

Battle Tip
It's not obvious but Illfang's HP actually has to be brought to 0 thrice! Don't relax after the first time and make sure to keep hitting hard!

You weren't able to avenge your friends, but maybe next time...

6wb

Oho? Seems like you got the relic after all. The Sacred Tree's Memory? No clue what this could do, but perhaps it'll be more helpful later on.

6wc

[7] Find the exit.

Enter the hole the boss made and press on.

Easter Egg
ee
While talking, Iori makes references to Kirito (SAO main protagonist).

You make it outside! Iori asks if you'd like to add them as a friend. They're a hardcore player so it often led to disagreements with more casual people. He enjoyed playing with you though and hopes you can keep the friendship.

6wb

Keep going on the road until you find the Terminal.

6wc

You and Iori take a moment to enjoy the realism of the game.

6wd

Interact with the sphere and get a summary of what you obtained from the dungeon.
