If you’ve ever saved up a full stock of Stellar Glow and Stellar Embers in Honkai: Star Rail, you’ve probably stood on the shop exchange screen hesitating: what should you pick to avoid wasting the rare resources you spent so long grinding for? Both Stellar Glow and Stellar Embers are special currencies earned by breaking down duplicate items pulled from gacha banners. Making the wrong exchange doesn’t just waste your hard-earned resources—it also slows down your entire character progression. This guide breaks down a clear exchange priority order to show you exactly how to get the most value out of your currency.
Stellar Glow Exchange Priority Breakdown
Stellar Glow is the currency you primarily get from breaking down duplicate pulled characters, and it’s fairly difficult to earn overall. You always need to prioritize core needs first when spending it, and you should never waste it on random low-value items.
T0 Highest Priority Exchange Items
No matter if you’re a new player or a mid-game Trailblazer, the number one priority for Stellar Glow will always be unlocking a permanent 5-star character. As long as you haven’t collected every permanent 5-star character yet, the team power boost you get from adding a new 5-star far outpaces any other item you could exchange for. Most permanent 5-stars aren’t just useful for new players—they also hold a consistent spot on rosters for late-game high-difficulty challenges, so you’ll never waste resources picking this option.
If you’ve already collected every permanent 5-star character, you can next save your Stellar Glow for permanent 5-star exclusive Light Cones. 5-star Light Cones have base stats and passive effects that are a full tier above 4-star Light Cones of the same role, so using one as an endgame piece for your core character is extremely valuable.
T1 Secondary Priority Exchange Items
Once you’ve claimed all your T0 priority items, any extra Stellar Glow can go toward the monthly-reset character progression materials. This includes Trace materials, ascension materials, and Relic choice chests, all of which are solid picks. For players constantly short on resources to level up new characters, exchanging these cuts down a ton of time you’d otherwise spend farming for materials.
Items You Should Never Prioritize
Low-tier basic materials, low-value currencies you can easily earn just by playing the game, and cosmetic items like avatars and emotes—you should absolutely never use your precious Stellar Glow to buy these first. These items have an extremely low value per currency spent, and buying them will only slow down how fast you finish building your full team.
Stellar Embers Exchange Priority Breakdown
Stellar Embers is the currency you primarily get from breaking down duplicate pulled Light Cones. You earn it a little more often than Stellar Glow, but it’s still a rare limited resource, so you still need to follow a priority order when spending it.
T0 Highest Priority Exchange Items
The number one priority for Stellar Embers is also permanent 5-star Light Cones. No matter if you’re missing a damage, survival, or support-type Light Cone, the boost a 5-star Light Cone provides is completely unmatched by 4-star options. Prioritizing unlocking the 5-star Light Cones you need is never a bad choice.
If you’ve already collected every permanent 5-star Light Cone, your next best move is exchanging for a selectable powerful 4-star Light Cone. Many top-tier 4-star damage Light Cones are endgame pieces for free-to-play teams, so unlocking one directly boosts your 4-star team’s damage output and still gives you incredible value.
T1 Secondary Priority Exchange Items
After you’ve claimed all your T0 items, any extra Stellar Embers can go toward monthly-reset Light Cone EXP and enhancement materials. If you’re building multiple teams at once, you’ll always be short on these resources, so exchanging them noticeably speeds up your progression. If you’re a casual player, you can also choose to unlock cosmetic items you like, just adjust based on your personal preferences.
Items You Should Never Prioritize
Just like with Stellar Glow, you shouldn’t waste Embers on low-tier materials or unnecessary duplicate items. Never waste months of saved Stellar Embers just for a tiny amount of common resources.
Overall Exchange Recommendations For Players At Every Progression Stage
New Players (Team Not Yet Completed)
When you’re still in the new player phase, you’re short on both characters and gear. No matter if you’re spending Stellar Glow or Stellar Embers, you should follow the priority order of 5-star characters > 5-star Light Cones. Get your core damage team built first before you consider any other items, and never waste resources on low-value picks.
Mid-Game Players (Have A Core Established Team)
Once you already have a core team that can clear most of the game’s content, you can save Stellar Glow to unlock extra Eidolons for your permanent characters, and use Stellar Embers to pick up any key Light Cones you’re still missing. Save any leftover resources for progression materials to speed up building your additional teams.
Endgame Completed Players (Full Permanent Collection)
Once you’re in late game and have collected every permanent character and Light Cone, you don’t have many restrictions left. Just buy whatever you’re currently missing. If you love collecting cosmetics, you can buy emotes or profile frames, and you never have to worry about losing out on value.
Overall, Stellar Glow and Stellar Embers are both rare currencies that take a long time to accumulate. Prioritizing buying characters and core gear will always give you the most value. As long as you adjust your priority order based on your current team progression, you won’t waste the resources you worked so hard to save up.
