Disable the Iridescent Beam

Once players arrive on Firethief's Secret Isle, they will be greeted with an Iridescent Beam who will shoot laser beams nonstop. Try to dodge all of its attacks while approaching and disabling it completely.

Complete the First Challenge

Complete the first challenge located beside the waypoint. This challenge requires players to indwell with the Yumkasaurs Spiritsconces beside it and disable all Iridescent Beams throughout the obstacle course.

Saurian Types and Names

How to Complete the First Challenge

	Objectives
1	Once the challenge starts, a string will come from above. This indicates that players can zip upward towards to disable the first Iridescent Beam
2	Another string will appear from behind which should lead the player to the second Iridescent Beam. Players should be careful not to overspam their zip-skill or they will fall.
3	A string will appear from behind which would lead the player to the last Iridescent Beam. Since there are no sigils, players can aim their zip-skill anywhere as long as its towards the Iridescent Beam.
4	The camera will then shift to a glowing symbol on the ground. Players should interact with it to activate the second challenge and get some rewards

Go to the Second Challenge

The second challenge is a bit forward and to the left of where the first challenge started. It is resting on a tiny island next to some Koholasaur.

Players are required to turn into a Koholasaur using the Saurian Spiritsconces nearby. This is so they could traverse the waters easily to complete the second challenge.

Saurian Types and Names

How to Complete the Second Challenge

	Objectives
1	Once the challenge starts, an Iridescent Beam can be seen from afar. Players should swim as a Koholasaurs and use its ability to swim faster. Simply interacting with the Iridescent Beam will disable it.
2	The next Iridescent Beam is also up ahead. However players shouldn't go forward as there are strong winds that push them back. Staying will also give the Iridescent Beam more openings to shoot the player.
3	Players should head left and jump over the obstacle to find the another Iridescent Beam on the way.
4	The last Iridescent Beam should also be up ahead, with no winds to stop the player.
5	Once players finish the challenge, another sigil and chest will spawn. Players should interact with both of them to continue.

Go to the Third Challenge

The third challenge is located at the other side of the island, opposite of where the second challenge is. The players are required to turn into a Tepetlisaur to destroy rocks and climb through the mountains by using the Saurian Spiritsconces nearby.

Saurian Types and Names

How to Complete the Third Challenge

	Objectives
1	After turning into a Tepetlisaurs, players could simply walk towards the Iridescent beam due to the Saurian's tanky health. However, an easier way would be to use the Tepetlisaur's ability to go underground to dodge the beams.
2	Quickly enter the orange hole to unlock a short cutscene of the Tepetlisaurs dodging every beam

Go to the Fourth Challenge

The fourth challenge is located on top of the Firethief's Secret Isle in the middle. The players will need to defeat three different elemental Wayobs to complete the fourth challenge.

Completing the challenge will also reward you with a Luxurious Chest that can reward you with an Iridescent Inscription Fragment.
