Butterfly Legends runs on a simple loop. You tap to train strength, spend gems on cases for stronger knives, equip the best trail and aura you own, then rebirth to lock in a permanent boost before starting the climb again. Every layer multiplies the last, so the fastest players keep gems, knives, trails, auras, and rebirths all moving up together instead of grinding one stat alone.
Quick answer: Tap to train strength, buy cases with gems to pull better knives, equip your highest-multiplier knife plus trail plus aura, then rebirth as soon as you hit the strength requirement to add a permanent Rebirth Boost (+12% per rebirth).
How to earn gems in Butterfly Legends
Gems are the main currency, and you need a steady flow of them to open better cases and reach higher areas. Several free sources refill your balance without spending Robux.
- Daily rewards run on a 7-day cycle. Day 1 pays 400 gems, and later days hand out gems, cases, and trails.
- Blue gem boxes spawn on the ground around the map. Walk over them to collect free gems as you explore.
- The Daily Chest gives a larger payout, such as 505 gems in a single claim.
- The Free Spin wheel rewards gems, extra spins, and auras.
- Playtime gifts drop small bundles like 50 gems for staying in the game.
- Selling duplicate knives returns gems; for example, 10 gems for a spare Rusty.
Playtime also grants a temporary x2 Power boost, running for a few minutes at a time, which doubles the strength you gain from tapping while it lasts.
Case prices and knife pulls
Cases are how you obtain knives, and each tier holds stronger blades. You can buy them with gems or with Robux. Spend gems on the cheapest case that still upgrades your current knife, and save higher-tier cases for when your gem income can sustain them.
| Case | Gem price | Robux price | Example knife |
|---|---|---|---|
| Wooden Case | 50 Gems | R$49 | Rusty |
| Iron Case | 550 Gems | R$99 | Tiger’s Fang, Fork, Epic Dagger |
| Crystal Case | 4K Gems | R$199 | Higher-tier knives |
After opening a case, go to the inventory and equip the knife with the highest strength multiplier. A fresh pull is worthless until it is equipped.
Stack knives, trails, and auras for bigger multipliers
Your total strength gain comes from three equippable slots working at once. A knife, a trail, and an aura each add their own bonus, and they combine, so always run the strongest version of all three that you own.
| Slot | Example | Effect | Source |
|---|---|---|---|
| Trail | Spark Trail | x1.15 multiplier | First rebirth |
| Trail | Frost Trail | Strength multiplier | Fifth rebirth |
| Aura | Light Aura | +4 strength | Third rebirth |
| Knife | Tiger’s Fang, Fork, Epic Dagger | Strength multiplier | Iron Case |
The Golden Machine gives a way to upgrade knives without gambling on cases. Feed it five knives, and it merges them into a single gold knife with a higher multiplier.
How rebirth works and the Rebirth Boost table
Rebirth resets your level and strength back to zero, but it hands over a permanent Rebirth Boost plus rewards like gems, cases, trails, or auras. That permanent boost is why rebirthing speeds you up rather than setting you back. Each rebirth adds another +12% to your strength gains, and the bonus stacks with every reset.
| Rebirths | Rebirth Boost | Example unlock |
|---|---|---|
| 0 | +0% | — |
| 1 | +12% | Spark Trail, Wooden Case |
| 2 | +24% | — |
| 3 | +36% | Light Aura, Iron Case (Fork) |
| 4 | +48% | Iron Case (Epic Dagger) |
The fifth rebirth requires around 13.14K strength and unlocks the Frost Trail. Open the rebirth menu to see your exact strength requirement for the next reset, then farm until you meet it.
Tip: Don’t sit far above a rebirth requirement. Once you can afford the reset, taking it immediately means your permanent boost starts multiplying every tap sooner.
Training zones that multiply strength
Not every training spot is equal. Some zones are locked behind a rebirth count and apply a large multiplier to the strength you earn while standing in them. As soon as you unlock a higher zone, move your grinding there instead of tapping in the starting area.
- The 1-rebirth training zone applies a 2x strength multiplier.
- The parkour obby area gives a 1.5x strength multiplier for clearing it.
The map also holds a PVP zone and locked portals such as the Pantheon of Gods, which open up as you progress deeper into the game.
The full progression sequence
The whole game rewards keeping every system in motion. Refill gems from free sources, upgrade knives through cases or the Golden Machine, keep your best trail and aura equipped, and rebirth on schedule so each +12% boost compounds. Do that, and your strength and gem totals climb far faster than tapping alone ever will.
