Lineage Piece Simulated Sea Guide – Skill Tree, Artifacts, Cards, and Sea Levels!

Lineage Piece has received one of its biggest endgame updates with the introduction of Simulated Sea and the new Skill Tree system. This update gives players a fresh progression path after reaching the late game, offering permanent upgrades, powerful artifacts, and special cards that can dramatically increase your strength. If you’re wondering how everything works, here’s a complete guide to the new system.

What is Simulated Sea in Lineage Piece?

Simulated Sea is a room-based challenge mode designed for endgame players. There are currently five sea levels available, with each level becoming much more difficult than the previous one. By completing runs, players can obtain:

• Bytes
• Artifacts
• Fragments
• Milestone rewards
• Cards
• Permanent upgrades through the Skill Tree

This mode will likely become one of the main activities for players looking to maximize their builds.

How Simulated Sea Runs Work

Every run contains 13 rooms. During the run, you’ll collect fragments and cards that strengthen your character temporarily. Building a strong setup throughout the run is essential because failing the final boss means receiving no rewards. Cards come in three rarities:

• Bronze
• Silver
• Gold

Gold cards are the most valuable and can significantly improve your damage and survivability.

All Room Types Explained

Combat Rooms

These are the most common rooms in Simulated Sea. You’ll fight two waves of enemies and earn fragments upon clearing them. There’s also a chance to receive cards after completing the battle. Combat rooms are the backbone of every run and help build your setup for later stages.

Fragment Rush

Fragment Rush is a timed room where players have 30 seconds to eliminate as many enemies as possible. Enemies drop large amounts of fragments, making this room one of the fastest ways to gather resources during a run.

Death Match

Death Match rooms contain two mini-bosses that must be defeated within one minute. Although more difficult, these rooms provide better rewards and offer higher chances of obtaining stronger cards.

Elite Rooms

Elite Rooms are among the most important encounters in Simulated Sea. Elite bosses have massive health pools, but defeating them rewards players with:

• Huge fragment gains.
• Guaranteed Gold Cards.

Whenever possible, prioritize clearing these rooms since Gold Cards can completely transform your run.

Rest Rooms

Rest Rooms allow players to spend fragments. Inside these rooms, you can:

• Upgrade cards.
• Purchase new cards.
• Improve your build before continuing.

Managing fragments wisely is important because better cards make later stages much easier.

Boss Room

Room 13 is always the final boss. This boss determines whether your run succeeds or fails. If you cannot defeat the boss before the timer ends, you receive nothing from the run. Because of this, creating a strong card setup throughout the previous rooms is extremely important.

All Simulated Sea Levels

• Sea 1 serves as an introduction to the system. Enemies are manageable and players can learn how rooms, cards, and fragments work.
• Sea 2 Enemies become noticeably stronger in Sea 2. Card choices start becoming more important, and poor decisions can make runs much harder.
• Sea 3 This is where difficulty starts increasing significantly. Players will need decent builds and stronger cards to progress consistently.
• Sea 4 introduces much tankier bosses and enemies. Upgrades, artifacts, and card management become essential for success.
• Sea 5 is currently the hardest difficulty available. Players need optimized builds and strong card combinations to complete runs consistently.

Artifacts Explained

Artifacts are one of the main reasons players farm Simulated Sea. After finishing runs, gems can be used to roll for artifacts. These items provide powerful bonuses that further strengthen your build. Artifacts also have sub-stats that can later be rerolled, allowing players to optimize their equipment even more.

Milestone Rewards

Fragments collected from Simulated Sea contribute toward milestone rewards. Some milestone rewards are especially valuable, including items that let players reroll artifact sub-stats. These rewards are important for players aiming to perfect their builds.

Skill Tree System Explained

The Skill Tree is another major feature introduced in this update. It uses Bytes, a resource earned through Simulated Sea runs. Every node unlocked grants permanent upgrades to your character. Unlike cards, which only affect a single run, Skill Tree bonuses remain forever. This means every run contributes toward long-term progression. As you unlock more nodes, your character gradually becomes stronger in various areas, making future runs easier.

Why Simulated Sea is Worth Farming

Simulated Sea offers multiple layers of progression at once:

• Permanent Skill Tree upgrades.
• Powerful Artifacts.
• Valuable milestone rewards.
• Gold Cards for stronger runs.
• A reason to continue progressing after reaching max level.

Even players who aren’t focused on artifacts should continue farming because the Skill Tree alone provides huge long-term benefits.

Simulated Sea is easily one of the biggest additions to Lineage Piece’s endgame. With five difficulty levels, powerful cards, artifact customization, and a permanent Skill Tree system, players now have plenty of reasons to continue grinding after reaching maximum level. Whether you’re chasing stronger artifacts or simply unlocking more Skill Tree nodes, Simulated Sea provides one of the best progression systems currently available in the game.
