If you’ve been staring at the Stardust Secret Crate menu in Once Human wondering why your rewards feel all over the place, I get it. In 2026, these crates still confuse a lot of players because the reward pools change dramatically depending on whether you’re opening a Rare blue, Epic purple, Legendary gold, or Mythic red crate. I’ve opened way too many of these myself, so let me break down the actual odds and what they really mean for your grind.

The first thing I always tell people is that not every Stardust Secret Crate is worth chasing for the same reason. Only Rare blue Stardust Secret Crates, which you get through activity, drop in-game resources and stat growth items. Epic, Legendary, and Mythic crates do not drop those progression resources. So if you’re trying to actually grow your character, chasing shiny red crates will not help you as much as you might think.

Rarity and Upgrade Chances

Stardust Secret Crates come in four rarities: Rare blue, Epic purple, Legendary gold, and Mythic red. Rare, Epic, and Legendary crates each have three chances to upgrade to a higher rarity, and a successful upgrade means better rewards when opened.

Upgrade Path Chance Per Attempt
Rare blue → Epic purple 5%
Epic purple → Legendary gold 4%
Legendary gold → Mythic red 4%

Does that sound low? It kind of is. But because you get multiple upgrade attempts per crate, the practical feel can be a bit better than a single sad 5% roll. Still, I would not plan your entire evening around hitting Mythic red on a Rare blue crate.

Current-Period Limited vs Always On Rewards

Before we dig into the numbers, there’s another important split. Cosmetic rewards are divided into current-period limited rewards and Always On rewards. Current-period limited rewards only come from the current Stardust Secret Crate. Always On rewards can show up from multiple different Stardust Secret Crates. So when you see an item in the Always On pool, it isn’t nearly as urgent to chase because it may return later.

That distinction matters more than it looks. If you’re after something like Stellar Remnant Drifter - Lonewolf's Whisper, that’s a current-period limited Legendary cosmetic. It won’t be around forever in the same crate rotation.

Rare Blue Crate: Best for Actual Progression

If I’m purely grinding for account growth, this is the crate I care about. It drops resources, supplies, and other useful things. But don’t expect generous Legendary cosmetic odds here because the base Rare crate pool doesn’t even list the current Legendary item at a normal rate.

Rare Blue Crate Reward Odds

  • Limited-time Epic rare cosmetic: 0.30% — includes Roasted Mushroom Ready - Growshroom and Silver River - Mini Wonder.

  • Limited-time Epic cosmetic: 2.70% — includes the full Pyro Dino set, Floating Light Wanderer Hat, and Night's Edge Crimson Blade Gloves.

  • Always On Epic cosmetic: 2.30% — includes the Wave Band sticker, Croissant weapon charm, Nutcracker cradle charm, Bloodbound Gloves, Candescence Top, and more.

  • Current period limited Rare cosmetic: 3.00% — includes Telepathy - Orb Lightning, Red Storm - Artisan's Touch, Vermilion Fortune - Wish Box, and the Wood Melody weapon skins.

  • Always On Rare cosmetic: 11.70% — includes Void Wings skins, Little Pyro Dino decal, Dustbound Egg cradle charm, and many furniture formulas.

  • Non-cosmetic resources and supplies: 80.00% — huge chunk, including Random Supply Crate at 45.00%, Mitsuko's Mark at 15.00%, Mod Dust at 11.25%, Battle Pass Exp at 5.00%, and Starchrom at 3.75%.

That 80% non-cosmetic rate is exactly why Rare blue crates are progression-friendly. You’ll get plenty of useful stuff, but don’t let the visible item list trick you into thinking you’ll walk away with cosmetics often.

Epic Purple Crate: The Middle Ground

Once you step up to Epic purple, the drop pool starts including the current Legendary cosmetic at a tiny rate. At the same time, you lose out on the actual resource/stat growth drops because this tier gives in-game currency instead.

Epic Purple Crate Reward Odds

  • Current season exclusive Legendary rare cosmetic: 0.15% — Stellar Remnant Drifter - Lonewolf's Whisper.

  • Current season exclusive Epic rare cosmetic: 0.45% — Roasted Mushroom Ready - Growshroom and Silver River - Mini Wonder.

  • Current season exclusive Epic cosmetic: 4.40% — Pyro Dino collection, Floating Light Wanderer Hat, and Night's Edge Crimson Blade Gloves.

  • Always On Epic cosmetic: 3.75% — includes the usual Always On purple items.

  • Current season exclusive Rare cosmetic: 6.00% — includes Telepathy - Orb Lightning and the Wood Melody series.

  • Always On Rare cosmetic: 25.25% — lots of formulas and Rare blue collectibles.

  • Non-cosmetic in-game currency: 60.00% — Silver Key at 18.00%, Colorful Badge at 16.60%, Mitsuko's Mark at 12.00%, Battle Pass Exp at 8.00%, Lightforge Relic at 4.80%, and Lightforge Ingot at 0.60%.

Honestly, Epic purple feels like the filler tier of 2026. It’s not bad, but the 60% currency rate plus the extremely low 0.15% Legendary rate means most openings won’t feel special.

Legendary Gold Crate: Finally Some Real Excitement

Legendary gold is where the current-period limited Legendary item starts to feel attainable. The rate jumps to 2.50%, which is still not huge, but it’s far better than Epic’s 0.15%.

Legendary Gold Crate Reward Odds

  • Current-period limited Legendary rare cosmetic: 2.50% — Stellar Remnant Drifter - Lonewolf's Whisper.

  • Current-period limited Epic rare cosmetic: 5.94% — Roasted Mushroom Ready - Growshroom and Silver River - Mini Wonder.

  • Current-period limited Epic cosmetic: 34.20% — the full current Epic cosmetic lineup.

  • Always On Epic cosmetic: 27.36% — the reusable Epic pool.

  • Non-cosmetic in-game currency: 30.00% — Lightforge Relic at 9.00%, Silver Key at 9.00%, Colorful Badge at 9.00%, and Lightforge Ingot at 3.00%.

This is the tier where your odds start leaning toward cosmetics instead of junk, but 30% is still a sizable amount of currency. Is it worth it? Only if you’re hunting the current Legendary or Epic cosmetics and you accept that nearly one in three pulls is still currency.

Mythic Red Crate: The Top-End Cosmetic Slot Machine

Now we’re at the crate everybody wants. Mythic red crates lean heavily into the current period’s top cosmetics. But notice something missing? No Always On items, no Rare blue items, and no actual resource or stat growth drops.

Mythic Red Crate Reward Odds

  • Current-period limited Legendary rare cosmetic: 30.00% — Stellar Remnant Drifter - Lonewolf's Whisper.

  • Current-period limited Epic rare cosmetic: 40.00% — Roasted Mushroom Ready - Growshroom and Silver River - Mini Wonder.

  • Current-period limited Epic cosmetic: 19.00% — Pyro Dino collection, Floating Light Wanderer Hat, and Night's Edge Crimson Blade Gloves.

  • Non-cosmetic currency: 11.00% — Lightforge Ingot at 10.00% and Lightforge Relic at 1.00%.

Mythic red is basically a targeted cosmetic crate. If your goal is to get Lonewolf's Whisper, this is the best shot you’re going to get by a mile. But even here, 11% of the time you’re walking away with just currency. Is that frustrating? Absolutely.

So Which Crate Should You Care About?

It depends entirely on what you want. Need resources and stat growth? Stick with activity-earned Rare blue crates. Want the current Legendary cosmetic? Your realistic path is hoping for upgrades to Mythic red or opening Legendary and Mythic crates directly. Just don’t let the flashy mythic glow make you forget that there are no progression drops inside.

After wrapping my head around these numbers, I honestly feel better about skipping the itch to chase every crate. Sometimes the smartest pull is the one you never spend extra on.
