Butterfly Legends: Farm Gems, Rebirth & Stack Upgrades
In Butterfly Legends, gems are the premium currency used for rebirths and permanent upgrades, and the most reliable way to farm them is by replaying the highest unlocked stage that you can clear quickly and consistently, while stacking the gem-boost upgrades from the skill tree and using the daily bonus and event rewards. Rebirths reset your stage progress but grant a permanent multiplier that increases gem drops, making each cycle faster and more lucrative. This guide explains the gem economy, how rebirth works, and the optimal order to stack upgrades.
How Gems Work in Butterfly Legends
Gems are the primary currency in Butterfly Legends, distinct from coins. You earn gems from:
- Stage completion bonuses (first-time clears and repeat runs)
- Daily login bonuses and timed events
- Rebirth rewards (a one-time gem payout per rebirth)
- Watching rewarded ads (if enabled)
Gems are used for two main things: purchasing rebirths (which reset your stage progress) and buying permanent upgrades in the skill tree. Unlike coins, which are spent on temporary in-run boosts, gems persist across runs and are the key to long-term progress.
The Rebirth System Explained
Rebirth is a prestige mechanic. When you rebirth, you lose your current stage progress and all temporary in-run upgrades, but you gain a permanent multiplier to your damage and gem drop rate. The rebirth cost scales with the number of times you have rebirthed, typically increasing exponentially. For example, the first rebirth might cost 100 gems, the second 200, the third 400, and so on. The multiplier gained per rebirth is usually additive, so two rebirths at +50% each give a +100% total bonus.
Key points:
- Rebirths are permanent and stack.
- You keep all purchased skill tree upgrades.
- Your stage progress resets to stage 1, but you will clear early stages much faster due to the multiplier.
- Each rebirth also grants a one-time gem bonus based on your highest stage reached.
How to Farm Gems Efficiently
The most efficient gem farming method is to find the highest stage you can clear in under 30 seconds, then replay it repeatedly. Because stage completion gives gems every time, speed is more important than pushing to a new maximum stage. For example, if stage 50 gives 5 gems per clear and takes 20 seconds, that is 15 gems per minute. If stage 60 gives 6 gems but takes 45 seconds, that is only 8 gems per minute. The former is better.
Steps to optimize your gem farming:
- Unlock the gem-related upgrades in the skill tree (e.g., “Gem Finder” that increases gem drop chance by 10% per level).
- Rebirth as soon as you can afford it, because the multiplier directly increases gem drops.
- Use the daily double-gem bonus window (if available) to farm during that time.
- Participate in events that offer gem rewards; they often give a large one-time payout.
- Watch ads for bonus gems when the option is available, especially during double-gem events.
Stacking Upgrades: What to Prioritize
Upgrades in Butterfly Legends fall into two categories: permanent (skill tree) and temporary (in-run). Permanent upgrades are the only ones that persist through rebirths, so they should be your priority. The most impactful permanent upgrades for gem farming are:
- Gem Drop Rate – increases the number of gems dropped per stage clear.
- Rebirth Multiplier – increases the multiplier gained per rebirth (if such an upgrade exists).
- Damage – allows you to clear stages faster, indirectly increasing gems per minute.
In-run upgrades (like temporary attack boosts) are useful for pushing to a new high stage, but they reset on rebirth. Spend coins on them only when you are attempting a new record, not during farming runs.
Common Mistakes and Misconceptions
One common mistake is hoarding gems to buy a high-cost upgrade instead of rebirthing early. Since rebirths give a permanent multiplier, they are almost always better than a one-time upgrade. Another misconception is that higher stages always give more gems per time. In reality, if your clear time increases disproportionately, you are better off farming a lower stage. Also, some players think that rebirth resets your skill tree – it does not. Only stage progress and temporary upgrades reset.
Comparing Farming Strategies
There are two main farming strategies: active and idle. Active farming involves manually replaying stages for maximum speed. Idle farming relies on offline progress or auto-battle features, which give gems but at a slower rate. For most players, active farming is better for gems, while idle is good for coins. If you have limited play time, use idle to accumulate coins and then spend a short active session to farm gems.
Safety and Fair Play
Do not use third-party tools, mods, or exploits to generate gems. These violate the game’s terms of service and can lead to a permanent ban. The game developers regularly update the game to patch exploits, and any progress gained through cheating is often rolled back. Play legitimately to keep your account safe.
Frequently Asked Questions
What is the best stage to farm gems?
The best stage is the highest one you can clear in under 30 seconds. For example, if you can clear stage 40 in 25 seconds, that is better than stage 50 in 60 seconds. Test different stages and calculate gems per minute.
How many rebirths should I do before upgrading the skill tree?
Rebirth as soon as you can afford it, because the multiplier increases your gem income. However, if you are very close to affording a high-level gem drop upgrade, it may be worth waiting a few runs to buy it first, since that upgrade will also increase your gem income.
Does rebirth reset my gem upgrades?
No, permanent upgrades from the skill tree are kept forever. Only stage progress and temporary in-run upgrades reset.
Can I get gems from watching ads?
Yes, many versions of the game offer a gem reward for watching an ad, usually once per day or per few hours. This is a safe and legitimate way to earn extra gems.
What is the fastest way to get gems early game?
Early game, focus on clearing stages as fast as possible and save your first 100 gems for the first rebirth. After that, the multiplier will speed up everything.
Is there a cap on rebirth multipliers?
There is typically no cap, but the cost increases exponentially, so the effective gain per gem spent diminishes. Eventually, you will reach a point where it is better to spend gems on upgrades that reduce stage clear time.
