Interastral Peace Guide/Survival Index

Welcome aboard the Astral Express, Trailblazer! Navigating the vast galaxy of Honkai: Star Rail can be as daunting as facing down a Stellaron, but understanding the core progression systems is key to strengthening your crew. The Interastral Peace Guide, particularly its Survival Index, acts as your mission control, outlining the essential activities for growth. This guide breaks down the most crucial features within the Survival Index—farming for character materials, targeting specific builds, and conquering the Simulated Universe—to help you chart a efficient course through the stars.

The Survival Index: Your Central Command for Growth

The Survival Index is your one-stop menu for all activities dedicated to bolstering your characters' power. Think of it as the "grind hub" of Honkai: Star Rail. Here, you'll spend your Trailblaze Power to obtain the specific items needed for leveling up, enhancing Traces, and equipping powerful Relics. It neatly organizes these critical tasks, ensuring you're never wondering where to find the next material for your favorite character.

Target Build: Your Personalized Progression Blueprint

One of the most valuable features within this system is the Target Build. This tool allows you to select a character you're eager to build, and the game will automatically calculate and display every single material you'll need for their full progression. It's like having a personalized checklist for your character's development.

Key details about the Target Build system:

Priority Characters: The game helps you focus by prioritizing characters with active or upcoming Event Warps in the catalog. Active Warps are marked "Warp," while upcoming ones are tagged "Preview."
Comprehensive Tracking: Once you select a target, the guide lists all required resources, including Stagnant Shadow Materials for ascension, Trace Materials (from Calyxes) for skill upgrades, and Generic Materials from enemy drops.
Relic Recommendations: Beyond basic materials, the system suggests the most optimal Relic and Planar Ornament sets for your chosen character. These recommendations are based on live player usage data and update daily, giving you a snapshot of the meta.

Core Farming Activities in the Survival Index

The Survival Index directs you to specific missions where you spend Trailblaze Power to earn rewards. Here’s a breakdown of the primary activities you'll be running.

Simulated Universe: Farming Planar Ornaments & More

The Simulated Universe is a roguelike game mode where you'll spend a resource called Immersion Points (which costs Trailblaze Power to replenish) to fight through simulated worlds and claim Planar Ornaments—a crucial type of equipment that forms a 2-piece set with a powerful bonus effect. Each world in the Simulated Universe offers specific Planar Ornament sets as rewards. Here’s what you can farm from the different worlds available:

World 3: Offers the Space Sealing Station and Fleet of the Ageless sets. Completing a run rewards 200 Trailblaze EXP and costs 1 Immersion Point (or 40 Trailblaze Power to directly obtain rewards).
World 4: Drops the Talia: Kingdom of Banditry and Sprightly Vonwacq sets.
World 5: Is the source for the Pan-Cosmic Commercial Enterprise and Celestial Differentiator sets.
World 6: Rewards the Belobog of the Architects and Inert Salsotto sets.
World 7: Provides the Rutilant Arena and Broken Keel sets.
World 8: Contains the Firmament Frontline: Glamoth and Penacony, Land of the Dreams sets.

Note: The specific worlds and available sets may be subject to updates or rotations in future game patches.

Calyxes: Your Source for EXP Materials and Credits

Calyxes are dedicated farming stages for the most fundamental progression resources. Located across various maps, they are your go-to for stocking up. The primary Calyxes available are:

Bud of Memories (Outlying Snow Plains): This is where you farm Character EXP Materials.
Bud of Aether (Backwater Pass): Focuses on Light Cone EXP Materials.
Bud of Treasures (Great Mine): The primary source for Credits, the universal currency.

Each of these stages can be run multiple times per wave, and the rewards scale with the difficulty level you choose.

Putting It All Together: A Strategic Approach

With these systems in mind, how do you use them efficiently? The Target Build tool is your best friend. Let's say you just pulled a new 5-star character and want to maximize them quickly.

Set Your Build Target: Navigate to the Target Build and select your new character. Instantly, you'll see a list of all required materials.
Consult the Lists: The guide will show you need, for example, specific Stagnant Shadow drops, Trace materials from certain Calyxes, and generic enemy drops.
Plan Your Farming: You can then:
- Run the specified Calyx (Golden) stages (like Bud of Memories) to gather the necessary Trace and EXP materials.
- Use Stagnant Shadow challenges to collect ascension materials.
- Use the Simulated Universe to farm for the recommended Planar Ornament sets.
- Defeat overworld enemies to collect the required Generic Materials.

This focused approach prevents you from wasting Trailblaze Power on unnecessary runs and streamlines your character-building journey.
