[Dinkum]Island Reef complete strategy guide | Thorough explanation of all limited item acquisition routes, optimal items to bring, and alpha shark subjugation techniques

In the vast world of Dinkum, one of the greatest joys from the middle to the end is exploring the island reef. This mysterious island can only be visited every Sunday, and its randomly generated map is littered with rare materials, exclusive creatures, and gorgeous treasure chests. Excitement awaits, including massive mining of aquamarine, fierce battles with alpha sharks, and chest hunts based on treasure maps.

This guide will thoroughly explain the conditions for opening the airport, preparing for departure, the efficient order of actions on the island, and detailed methods of obtaining all limited items. We will carefully explain common mistakes and advanced techniques so that even first-time visitors can achieve the full harvest without hesitation. If you're well-prepared, you can bring home millions of dinks worth of value in a single expedition. Let's conquer the seas of Dinkum.

1. What is Island Reef? Complete understanding of release conditions and basic outline

Island Reef is a special biome added in the Summer Sun Update that is a beautiful island dotted with tropical coral reefs and sunken ships. You can only visit from Sunday morning until night, and the map is completely randomly generated each time, making each exploration a fresh adventure. The central part of the island is covered with lush vegetation, surrounded by the blue ocean, and countless sparkling aquamarine ores lie on the ocean floor.

First you need to build an airport to access it. When the in-game time has entered the second year and 11 or more residents have settled on the island, the construction menu will be unlocked by speaking to Fletch after meeting Nancy's settlement conditions. Nancy can be summoned to the island by completing certain quests.

The materials required for construction are as follows.

• Eucalyptus wood boards: 25 pieces
• Palm wood planks: 25 pieces
• Cement bags: 15 bags
• Iron bars: 10 pieces
• Copper bars: 10 pieces
• Crystal: 10 pieces
• Cloth: 5 pieces
• Dink: 2,500,000 Dink

Once the airport is completed, you will purchase a boarding pass from Nancy for 250,000 Dink on Sunday morning and board the airship through the entrance opposite the counter. In the case of multiplayer, the aircraft will depart after everyone has boarded.

A characteristic of the island is that after midnight, green poison particles are generated and damage will be taken every 2 seconds. It is important to take to the skies by helicopter or evacuate as soon as possible. Although NPCs cannot accompany you, the appeal is that you have a very high degree of freedom in exploration. If you conquer this island, your economy will instantly stabilize with expensive aquamarine shards and limited edition decorations.

2. List of essential items to bring before departure and why

The island reef is vast and has many underwater elements, so the selection of items you bring will determine 80% of your success. If your inventory is full, you will have to give up treasure chests, so it is essential to prepare to make use of the maximum capacity. Below we list the best things to bring in each category and explain the reasons for each in detail.

Transportation (top priority)

• Jet Ski or Helicopter: The island is surrounded by water, so boogie boards alone are too slow to get around. Jet skis glide across the sea at high speed, and helicopters provide a bird's-eye view of the entire area. It's a good idea to bring a glider with you in case of an emergency.

Underwater equipment (lifeline)

• Diving Helmet: This is the only item that allows you to use pickaxes and hammers underwater. Essential for destroying sunken ships and mining aquamarine.

exploration tools

• Old keys: 100+ (for 20 treasure maps). Collect them in crab cages or fishing. For every 5 shark statues consumed, you will receive 1 map.
• Shovel: For digging treasure chests only. I bring several bottles with me for durability.
• Pickaxes, axes, insect nets, fishing rods: Required for capturing limited plants, ores, and creatures.

Combat/Survival

• Powerful weapons (Alpha Trident recommended) and armor: Save your life in the Alpha Shark battle.
• Buff foods such as premium steak and young soup: Enhances HP and attack power. Bring multiple stacks.
• Substitute vehicle (cart or wagon): For inventory expansion. You can leave your items on the island and collect them all when you return.

Forgetting these things will greatly reduce your efficiency. Especially if you don't have enough keys, you won't be able to hunt treasure chests. Many players focus on collecting keys a week in advance.

3. Optimal search route and priority action order immediately after arrival

Once you arrive on the island, decide on a route to make the most of your time. The map is random, but the basic pattern is “Search for statue → Treasure chest → Cooler → Sunken ship → Mining''. The fastest way to quickly locate the statue is to use a helicopter to scan the entire area from above.

1. Search for shark statues (5-10 minutes): There are 1-2 shark statues somewhere on the island. Insert 5 keys and get all 20 maps. Do not move the statue until the end, and take it home after getting 20 statues.
2. Treasure Map Hunt (30-60 minutes): Dig the X marks on the map in order with a shovel. Efficiency increases by prioritizing nearby areas. Chests yield paint, decorations, slingshots, and more.
3. Cooler collection (parallel): Scattered all over the island. Ice cream makers and high-performance slingshots are likely to appear.
4. Found a sunken ship → Killed an alpha shark: There are 1-3 locations on the ocean floor. If you destroy the hammer with a diving helmet, a shark will appear, so lead it to land and fight it.
5. Aquamarine mining and creature capture: Use the remaining time to dig undersea rocks with a pickaxe, and use nets and rods on the sea surface. Don't forget to collect plants such as pineapples.

Prioritize evacuation as night approaches. Distribute items to substitute vehicles to prevent overcapacity. You can take home up to 200 items or more per day using this route.

4. Complete list of rare items limited to Island Reef and how to get them

The true value of this island lies in its limited edition items. Below is a complete list of each category and how to obtain them. We recommend multiple rounds to avoid duplication.

From the treasure chest (map/cooler)

• Ice cream maker: There is a high probability that it will appear from the cooler box. Once we obtain multiple items, mass production will begin.
• High-performance slingshot, stone staff: Appears mainly in blue boxes. Long range combat will be greatly enhanced.
• Silver pocket watch, artificial grass, pirate glider: rare frames. Useful for time manipulation and decoration.
• All types of paint (including gold/chrome): Essential for customizing your home.

subjugation/mining

• Alpha Shark Teeth: Obtained by defeating sharks. Alpha trident creation material.
• Aquamarine Fragment: Seafloor ore can be quadrupled with the crusher. John can sell it at a high price.

Found/captured

• Rotating Clothesline: There are 1-2 underwater. Collected by diving.
• Collect plants and ores: pineapples, pearls, parasols, belconium ore, jet ski parts.
• Limited creatures: Various tropical fish, tropical butterflies, crabs, etc. Catch them with a net and take them back to the farm.

Selling these items at John's Goods is the best way to make money. It is not uncommon to earn more than 500,000 dinks in one round.

5. Detailed guide to defeating Alpha Shark: Weaknesses, routes, and drop rewards

The biggest challenge on the island is the alpha shark. Appears when you destroy a sunken ship (1-3 random locations on the ocean floor) with a hammer while equipped with a diving helmet. Since you are at an overwhelming disadvantage underwater, it is important to choose a ship close to land.

To prepare, fill up your attack power and HP buff food, and equip yourself with Alpha Trident and high-class guns. The strategy is to follow the shark and guide it to land, then attack it repeatedly from behind while avoiding its jump attacks. Although it has high HP, it can be defeated in 5-10 minutes on land.

The rewards are mainly alpha shark teeth, but you can also get scales and meat. There are many cases of failure that result in instant death in underwater battles, so please thoroughly guide them on land.

6. Efficient take-home techniques: Tips for inventory management and loaner vehicle operation

Inventory management is very important as the yield is huge. Bring in multiple substitute vehicles (carts and carts) and collect them in the center of the island. Items are deposited periodically during exploration and collected in bulk upon return. This will prevent you from being overweight and allow you to open all the treasure chests.

The basic idea is to take light items home directly and leave heavy ore to a loaner vehicle. Please be sure to collect all items before boarding the airship.

7. Tips for advanced users: Utilization of financial strategies and lap optimization techniques

• If you sell aquamarine pieces by weight, you can make a huge profit. It is also effective to breed and sell limited species.
• The key is crab cages, which allow you to farm infinitely. By memorizing the map you can instantly find the statue.
• In multiplayer, the division of roles is powerful. Ideally, one person will be in charge of statues and the other person will be in charge of mining.
• Poison rain has been strengthened, so keep a helicopter on hand at all times.

8. Summary: Conquer the island reef and reach the top of Dinkum

Island Reef is a great area that can bring you endless wealth and joy if you prepare well. If you follow this guide, you'll reap the rewards right from the start. It's a long road starting with the construction of the airport, but the sense of accomplishment is exceptional. Please look forward to every Sunday and make the island even more prosperous. Dinkum's adventure continues.
