Shells Mountain & Sky Island Update Guide – Codes

Shells has finally released the Mountain & Sky Island update, and this patch adds a huge amount of new progression content for players to explore. Instead of being a small update with just a few items, this one completely changes how progression works by introducing Sacred Relics, Sky Island access, new quests, powerful Tide Claws, and several new locations connected together through one large system.

A lot of players are confused after entering the update because the game does not fully explain where to go first or how all the mechanics connect. Some players are searching for relics without knowing where they spawn, while others are trying to unlock Tide Claws before completing the required quests.

This guide covers everything important in the update including all Sacred Relic locations, how to unlock Sky Island, where to find the new Tide Claws, and how the new progression system works overall.

New Shells Codes

Before starting the update, make sure to redeem the newest working codes because they give useful free rewards.

Working Codes

  • MountainAndSkyIsland
  • FastFastFast

These codes currently reward Lucky Rolls, spins, and other bonuses that can help during progression.

Since Shells update codes usually expire quickly, it is better to redeem them immediately instead of saving them for later.

Everything Added in the Update

The Mountain & Sky Island update adds:

  • Sacred Mountain
  • Sky Island
  • Sacred Relics
  • New Tide Claws
  • New quests
  • New NPCs
  • New tools and shells
  • Forge of God progression
  • Multiple new islands

This update is heavily focused on exploration and progression rather than simple combat grinding.

How the New Progression System Works

The main progression path starts at Sacred Mountain.

Once you arrive there, your goal is to collect:

Three Sacred Relics

These relics are hidden across multiple islands and are required for continuing the update questline.

Without collecting all three relics, you cannot properly progress into the later parts of the update like Sky Island access and advanced Tide Claws.

The update is designed to slowly guide players through exploration before unlocking the stronger rewards.

First Sacred Relic Location

The first Sacred Relic can be found at:

Sea Stack Island

Once you arrive at the island, search around carefully and you should eventually spot the relic.

This is generally the easiest relic to collect, so many players start here first before moving to the other locations.

The relic itself is not too difficult to find once you know the correct island.


Second and Third Sacred Relic Locations

The remaining relics are located at:

Crescent Shore

This island is important because:

Two Sacred Relics Spawn Here

A lot of players accidentally leave after finding only one relic, so make sure to fully explore the area before leaving.

Once both relics are collected, you will officially have all three Sacred Relics required for progression.

How To Unlock Sky Island

One of the biggest additions in the update is Sky Island.

To unlock access, players need to continue progressing through the Sacred Mountain content first.

According to the update progression, players must:

  • Reach Sacred Mountain
  • Bring a friend
  • Find the Summit of Bliss

After completing those requirements, players can travel to the Sky Island area.

This part of the update feels much more adventure-focused compared to older Shells content.

Divine Tide Claw Location

One of the major new weapons added in the update is the:

Divine Tide Claw

However, players cannot unlock it immediately.

To interact with this Tide Claw properly, you first need to complete:

Forge of God Quest

This acts as one of the main progression checks in the update.

Once the questline is completed, you can finally obtain the Divine Tide Claw.

Silendria’s Specter Tide Claw

Another new addition is:

Silendria’s Specter Tide Claw

This Tide Claw is also tied to quests and progression systems, meaning players must continue through the update before fully unlocking it.

It appears designed for stronger players looking for late-game tools.

Sanctum Tide Claw

The:

Sanctum Tide Claw

costs:

14 Million

making it one of the more expensive additions in the update.

Players will likely need to grind currency for a while before unlocking this one.

Sunveil Tide Claw

Another extremely powerful addition is:

Sunveil Tide Claw

This Tide Claw costs:

20 Million

and is located near:

Keep of Solon

Because of its price and placement, it clearly seems intended for advanced progression players.

Aether and Helios Sunspace Tide Claws

The update also adds:

  • Aether Tide Claw
  • Helios Sunspace Tide Claw

These are currently some of the:

Most Expensive Tide Claws in Shells

with prices reaching:

  • 30 Million
  • 45 Million

These tools are clearly aimed at late-game players grinding high-level progression.

Why This Update Feels Different

One reason this update stands out is because nearly every feature connects together.

Instead of simply adding:

  • One boss
  • One weapon
  • One island

the developers created an entire progression system involving:

  • Exploration
  • Questlines
  • Relic collection
  • Currency grinding
  • Unlockable travel areas
  • Powerful endgame tools

The update feels much more like a full expansion rather than a simple content patch.

Best Things To Do First

If you are starting the update for the first time, these should be your priorities.

Redeem the New Codes

Free rewards always help early progression.

Collect All Three Sacred Relics

This is the main requirement for progression.

Visit Sea Stack Island First

It contains the easiest relic.

Fully Explore Crescent Shore

Remember that two relics are hidden there.

Start the Forge of God Questline

Several Tide Claws require it.

Save Currency

The strongest Tide Claws are extremely expensive.

The Mountain & Sky Island update adds a huge amount of progression content to Shells. Between Sacred Relics, Sky Island progression, Forge quests, and the massive collection of new Tide Claws, the update feels much deeper than most previous patches.

The update also encourages exploration much more than older content, which makes progression feel more rewarding overall.

If you want to progress efficiently, focus on collecting the Sacred Relics early, complete the important quests quickly, and start saving currency because some of the strongest Tide Claws in the update cost an enormous amount of money.
