Honkai Star Rail 2.3: The Ultimate Radiant Feldspar Treasure Hunt Guide

When Version 2.3 of Honkai: Star Rail dropped back in 2024, Trailblazers were buzzing with excitement. The update wasn't just about new characters or story quests; it unveiled a brand-new, treasure-laden location within the dreamscape of Penacony: the Radiant Feldspar. Fast forward to 2026, and this majestic ship remains a must-visit spot for any Astral Express crew member looking to beef up their Stellar Jade count and snag some unique collectibles. While it didn't feature the mind-bending 3D planes of other Penacony zones, the Radiant Feldspar offered a classic, sprawling exploration experience packed with goodies. For the completionists out there, this guide is your golden ticket to cleaning house. Let's dive in and find every last chest and those two elusive Lordly Trashcans. It's time to go on a proper treasure hunt, no stone left unturned!

All F1 Floor Chest Locations (The Main Deck)

The first floor is where the party's at. It's the heart of the ship, with lounges, stages, and plenty of nooks to hide treasure. Seven chests are waiting for you here. Pro tip: Start from the bottom Space Anchor and work your way up. It's the most efficient route, trust me.

Here’s the breakdown of where to find 'em all:

Chest #	Location & How to Find It
1	Teleport to the bottom space anchor. Head down the grand staircase, and you'll spot this chest chilling on your right. Easy peasy.
2	From Chest 1, keep heading north. You'll find the next one tucked away in a secluded area on your left. Don't blink, or you might miss it!
3	Take the path to the right in this area. Look for a circular secluded spot with a table; the chest is right there.
4	Venture into the central area of the deck. This chest is sitting pretty on the northernmost part. It's kinda hard to miss once you're in the middle.
5	Go through either of the two doors in the middle of the Feldspar. Take the stairs up, and you'll find this chest waiting in the hallway between them.
6	Head to the front (or top) area of the ship through those same middle doors. This chest is hiding in the top-left corner of that section.
7	From Chest 6, go north and enter the stage area. The final chest for this floor is on the right side of the stage. Encore! 🎭

All F2 Floor Chest Locations (The Upper Decks)

Time to level up—literally. The second floor houses five more chests and connects to some key activity areas. If you've unlocked the Origami minigame here, you've got a perfect starting point. Otherwise, those central stairs from F1 are your best friend.

Let's get that loot:

Chest #	Location & How to Find It
1	Best starting point: Teleport to the Origami minigame anchor. The chest is on the northeast side of the room. No minigame access? Just take the stairs up from the F1 middle room.
2	Exit the Origami room from the left side (on your map) and head south. You'll bump into this chest pretty quickly.
3	After grabbing Chest 2, haul it all the way north. Go through a door, and you'll find the next chest immediately on your right.
4	Teleport to the Divergent Universe area (Simulated Universe access). Go up the curved stairs, and the chest will be right there.
5	From Chest 4, enter the ship's main driving area by going north. This final chest is right near the steering wheel. Captain's orders! ⚓

All B1 Floor Chest Locations (The Lower Decks & Hidden Trashcans)

Ah, the lower decks. This is where things get interesting. Not only are there six more treasure chests down here, but you'll also find the crown jewels of Penacony exploration: two Lordly Trashcans. These aren't your average junk piles; interacting with them grants unique achievements and items. Finding them is a real flex.

Here's your treasure map for the basement:

Item #	Type	Location & How to Find It
1	Chest	Head to the bottom Anchor in Radiant Feldspar. Go down the stairs to reach a cabin on the lower floor. The chest is inside, plain as day.
2	Lordly Trashcan	Jackpot! This glorious trashcan is in the same cabin as Chest 1. One man's trash is literally your treasure here. 🗑️✨
3	Chest	Teleport to the Midship Lounge space anchor. Go behind the stairs, and you'll find this chest tucked away.
4	Lordly Trashcan	Double jackpot! The second majestic bin is sitting right in front of Chest 3. A two-for-one special!
5	Chest	Head to the main lounging area on B1. There are two side rooms. Find one chest in the left-side room.
6	Chest	In the main B1 lounge area, find the other chest in the right-side room. Symmetry is key!

Final Tips for the Aspiring Treasure Master

By now, you should have a clear path to 18 total treasures (12 standard chests, 4 precious chests, and 2 Lordly Trashcans) aboard the Radiant Feldspar. To make your run as smooth as butter, remember these pro-gamer moves:

• Follow the Flow: The order presented here is optimized for minimal backtracking. Stick to F1 -> F2 -> B1.

• Anchor Advantage: Unlock all Space Anchors as you go. It'll save you tons of time if you need to return.

• Trashcan Triumph: Don't just walk past those Lordly Trashcans! Interacting with them is a non-negotiable part of the 100% completion grind.

• Eyes Peeled: Some chests are in slightly obscured corners. Use your camera angles!

There you have it, Trailblazers. The Radiant Feldspar might be an older map, but its treasures are timeless. So gear up, set your destination, and get ready to plunder. Happy hunting, and may your Jade count be ever in your favor! 🚂💎
