Where is Crane Key in Raft The Final Chapter?

Raft: The Final Chapter came with three new destinations for you to find, explore and make your way through. These are Varuna Point 6277, Temperance Ice Island, and an unnamed third destination. You can read our Raft Temperance Ice Island guide to find all the available activities, or the Raft New Characters guide and learn how to unlock all.

The Crane Key is related to Varuna Point 6277, a sunken island with much construction equipment left behind. Operating the Crane is one of the first missions you’ll get on the Island.

How To Find Crane Key in Raft

Before we explain where to obtain the Crane Key in Raft: The Final Chapter, be informed that this guide will cover certain story elements that may spoil the story for you, so proceed at your own discretion.

Whether exploring Varuna Point 6277 on your own or with a party, you should have oxygen tanks, fins, and a zipline. As parts of the Island are sunken, you’ll often be required to dive underwater and zipline across.

You will find Food and Drinkable Water along the way, but it won’t hurt if you have some extra supplies. If you’re exploring Varuna with a party, ensure that you have enough Healing Slave for everyone.

Climbing Up To Crane on Varuna Point

As you set foot on the Island, your first mission will be to gain access to the Crane. You need to climb to the top of the building, where the Crane operating cabin is. You’ll encounter many rats in the building, so have your sword on the standby.

After some puzzling navigation and parkour bits, you’ll find yourself next to the Crane Controls. Here, the game will inform you that to operate the Crane, and you need a Crane Key.

Going Underwater and Raft Motherlode Key

In typical Raft fashion, your mission to operate the Crane will take you to different parts of the Island. You’ll need to dive underwater from the building you were just on. You’ll need to explore around, looking out for spotlight-esque light fixtures.

In the area illuminated by the light, there will be an opening guarded by a swarm of jellyfishes, so time your move and get in. Inside these areas, you’ll find Notes and other collectibles. Anglerfish, a new enemy type introduced in the Raft: The Final Chapter update, roam these waters.

The update also brought along Trash Cubes, explained in our Raft Trash Cubes guide.

Be on the lookout for these fish, as they do a rush attack with considerable damage. Once you are done exploring and collecting the three spotlight parts, get out of this area and look below to see another spotlight. Turn on the spotlight to disperse the jellyfish. There will also be Air Bubbles next to the light to replenish your Air Supply.

Head into the tunnel illuminated by the light. You’ll have to explore around to get up, so be sure to manage your Air from the various Air Bubbles properly.

Once you’re out of the water, you need to get to the end of this section. The area is littered with booby-traps (spiked boards on the floor, spiked tubes, and boards that swing from the ceiling), so beware of them.

Finding the Motherlode in Raft

After collecting the Raft Motherlode Key, you’ll need to explore a bit to find the exit door. A map will be drawn on the wall next to the exit door, marking the Motherlode.

For the next bit, you need not worry about your Air Supply as the Air Bubbles are abundant here. Once you leave this area, swim downwards until you reach an opening with luminescent, colorful coral reefs.

Enter here, and you’ll arrive at a Garage Door with Air Bubbles next to it. Enter through the door, and you will be in the Motherlode.

We won’t spoil what the Motherlode is right now to preserve your adventurous intuition. All you need to know for now is that you should be looking out for a wall marked with a large ‘G.’

Rhino Shark Boss Fight in the Motherlode

Inside the Motherlode, you will face the Rhino Shark boss. The Shark will rush to attack, damaging your Oxygen Tanks and drowning you. You need to keep your distance, guiding the Rhino Shark to smash into one of the four pillars in this arena.

Doing so will drop an explosive barrel, which needs to be placed in the opening in the pillar. Get the Shark to ram into the same pillar once again to stun it for a couple of seconds, allowing you to swim up through the hole (caused by the pillar collapsing) into the second phase of this boss fight.

Repeat the same trick here to collapse a pillar, allowing you to proceed to the third and final phase of the Rhino Shark boss fight. In the third phase, a pile of explosive barrels will be on the ground.

You may want to guide the Shark into the pile, but doing so will leave you stranded in this arena with nowhere to go. You actually need to take one barrel, place it in the pillar, and guide the Shark to ram into the pillar for one last time.

Then, zipline to this hole and go into the office down below to pick up an Advanced Battery blueprint and a note which will unlock the following location for you. Also, pick up the briefcase next to the blueprint, which may drop Titanium. You can explore if you want to, after which you can leave the area.
