The single hardest decision in Mine a Planet is choosing when to trigger your first Rebirth, because the Prestige Points you earn are calculated based on your level, your reforged drills, and your cleared planets at the moment of reset. Reset too early and you leave thousands of potential Prestige Points on the table. Reset too late and you burn hours grinding levels that no longer matter. This guide walks through the precise math behind Prestige Points, the optimal first-rebirth timing, the second-rebirth unlock requirement, and the reforge cycle that maximizes your long-term Prestige Point income.
The Rebirth system is the central progression loop that separates casual players from committed grinders, and the developers have tuned it deliberately so that the players who plan their resets around reforge milestones earn roughly 40-60% more Prestige Points per cycle than players who just reset the moment they hit level 25. Learning the math behind that spread is what unlocks the true end-game of Mine a Planet.
Understand How Prestige Points Are Calculated
Prestige Points are awarded based on three inputs at the moment of reset: your player level, the number of reforged drills you have bound to your account, and the number of planets you have fully cleared. Each input contributes a flat multiplier to your total Prestige Point payout, and the multipliers stack additively. The base payout at level 25 with no reforges is roughly 100 Prestige Points, while a level 25 reset with a bound Legendary drill and three fully cleared planets can grant 500+ Prestige Points.
| Rebirth Inputs | Prestige Point Multiplier | Cumulative Payout (level 25) |
|---|---|---|
| Base level 25 reset | 1.0x | 100 PP |
| + Bound Common drill | +0.5x | 150 PP |
| + Bound Rare drill | +1.0x | 200 PP |
| + Bound Epic drill | +2.0x | 300 PP |
| + Bound Legendary drill | +4.0x | 500 PP |
| + Each cleared planet (Earth-Mars-Europa) | +0.5x per planet | 650 PP (all 3) |
The numbers above are based on community testing of the UPDATE1 patch and may shift slightly with future balance updates. The general direction — bound Legendary drills and full planet clears are the dominant Prestige Point contributors — has been consistent since the game launched.
The Optimal First-Rebirth Timing
For most players, the optimal first rebirth triggers the moment you have reforged a Mythril Destroyer (or your highest available Legendary drill) and have fully cleared at least three planets. This typically happens around level 30-35, not the bare minimum level 25. The reason to wait is that the Prestige Point payout jumps sharply when you bind a Legendary drill, and binding a Rare drill first is a wasted opportunity because the same time investment could have yielded a Legendary.
The standard timing for a focused player is roughly 4-6 hours of active gameplay to reach the optimal first-rebirth state. During that window, you should be focused on three goals in order: reach level 25 to unlock the Rebirth screen, craft a Mythril Destroyer or your highest available Legendary, and reforge that drill until it rolls a high Ore Multiplier stat. Once those three checkpoints are met, trigger the reset immediately and do not delay any further. Players who push past level 35 to grind more ore before their first reset typically earn diminishing Prestige Point returns because the base level multiplier tops out around level 50.
Why the Second Rebirth Matters Even More
The second rebirth unlocks the Prestige Shop, which is the central end-game progression system. The Prestige Shop sells exclusive drills, smelter upgrades, and permanent multipliers that are unavailable to first-rebirth players. To qualify for the second rebirth, you need to reach level 50 AND have at least one Cosmic Reaper or higher Legendary drill bound to your account. This is a much higher bar than the first rebirth, and most players spend 10-15 hours grinding to reach it.
The Prestige Shop's most valuable offerings are the Ore Multiplier III upgrade (which triples your ore income), the Drill Speed III upgrade (which doubles your swing rate), and the exclusive Astral Annihilator drill recipe. Each of these is gated behind a minimum rebirth count, so the sooner you reach your second rebirth, the sooner you can start saving toward these upgrades. For a complete walkthrough of the Prestige Shop and the optimal spend order, see our Mine a Planet prestige guide.
Spend Prestige Points in the Right Order
The Prestige Shop has roughly a dozen upgrade paths, and not all of them are equally valuable. The community-tested optimal spend order starts with Ore Multiplier, because it compounds with every other system in the game. Drill Speed is the second priority for the same reason. Rare Drop Chance is a strong third because it directly affects late-game material income. Smelt Speed and XP Bonus come last because they are situational.
| Priority | Upgrade | Effect | Approximate PP Cost |
|---|---|---|---|
| 1 | Ore Multiplier I | +25% ore income | 200 PP |
| 2 | Ore Multiplier II | +50% ore income | 500 PP |
| 3 | Drill Speed I | +15% swing rate | 300 PP |
| 4 | Drill Speed II | +30% swing rate | 800 PP |
| 5 | Rare Drop Chance I | +10% rare drops | 400 PP |
| 6 | Smelt Speed I | -10% smelter time | 350 PP |
| 7 | XP Bonus I | +20% XP gain | 250 PP |
The exact PP costs above are based on the UPDATE1 patch. They may shift with future updates, but the general priority order has remained stable for multiple patches and is unlikely to change dramatically. This principle applies broadly across all progression stages and is one of the most reliable optimization levers in the game.
Use Reforge Cycles to Reset for Free Drill Pieces
There is a clever trick that experienced players use to earn massive Drill Piece payouts from reforge cycles. The cycle works by reforging a Legendary drill until it rolls a near-perfect stat spread, binding that drill at the moment of rebirth, then repeating the process with a different Legendary after the reset. Because the bind persists across rebirths, you can essentially trade Prestige Points for the time investment of rolling perfect drills on every reset cycle.
The optimal rebind schedule is to bind a fresh Legendary on every third rebirth. This gives you roughly 15-20 hours between binds, which is enough time to accumulate enough Drill Pieces to fund a Legendary reforge campaign. Players who bind every single rebirth typically run out of Drill Pieces for reforge within two cycles, which forces them back to grinding ores before they can afford the next big reforge.
Advanced Rebirth Timing Optimization
For end-game players who are pushing for absolute maximum Prestige Points per hour, the timing strategy becomes much more nuanced than the basic first-rebirth guidelines suggest. The most important advanced technique is the batch rebirth window, where you deliberately delay your rebirth until you have stacked enough bonus hours to justify resetting a high-value crafting bench that is currently producing rare materials. Players who learn to read their own resource production curve can extract 20-30% more Prestige Points per calendar hour than players who simply rebirth on cooldown.
A related optimization is the smelter overflow reset, where you intentionally let your smelter queues run dry before triggering a rebirth, then immediately queue a fresh 100-stack batch on the new planet. This avoids the common mistake of triggering a rebirth while the smelter is still processing batches of low-tier ores that become worthless on the new planet. The one-batch lag is a small cost compared to the value of starting the new planet with a clean queue. Tracking your smelter utilization across multiple rebirth cycles is a reliable way to identify when this optimization applies.
The third advanced technique is the prestige shop stockpile strategy, where you save up 5-10 rebirths worth of Prestige Points before spending any of them. This is most useful when a specific shop upgrade has a steep step-cost — for example, the second tier of the Ore Multiplier upgrade costs 50% more than the first, and players who can stockpile through two rebirths at a time hit the discount breakpoints much faster. For more details, see our reforge cost strategy guide which covers the exact Prestige Point thresholds for each shop tier.
Finally, players who have unlocked the Second Rebirth and the Astral Annihilator can use a prestige-bombing approach where they reset multiple times in rapid succession to compress the early game of each cycle and reach the high-tier drilling zones faster. This is risky because it starves your Prestige Point income in the short term, but the long-term benefit is that you can unlock the Mythic-tier reforges much sooner. The optimal bombing cadence is once every 3-4 normal rebirths, which keeps the Prestige Point income steady while still accelerating your overall progression toward the end-game grind on Nebula and Void planets.
Cycle Timing Windows
Each rebirth cycle has natural time windows.
| Window | Duration | Bonus |
|---|---|---|
| Cooldown | 0-30m | None |
| Peak grind | 1-4h | +10% |
| Diminishing | 4-8h | +5% |
| Over-grind | 8h+ | -5% |
Frequently Asked Questions
Should I trigger my first rebirth at level 25 or grind to a higher level?
Level 25 unlocks the Rebirth screen, but the optimal reset is at level 30-35 with a reforged Legendary drill. Resetting at the bare minimum of level 25 without a bound Legendary typically yields only 60-70% of the Prestige Points you could have earned with a slightly longer grind.
What happens to my drills after I rebirth?
Any drill you have not bound to your account is destroyed. Your bound drill persists across the reset along with its reforge stats. Everything else — your level, your ore inventory, your smelter queue — is wiped back to the starter state.
Can I change which drill is bound mid-cycle?
No, the bind is locked at the moment you trigger the rebirth. There is no unbind option. Choose carefully which drill you bind, because you will not be able to swap it until the next rebirth. The optimal drill depends on your current biome and active pet bonuses, but the highest-tier drill you can craft is usually the right answer.
How many rebirths does it take to max out the Prestige Shop?
Community estimates range from 8-12 full rebirth cycles to fully max every Prestige Shop upgrade path. With consistent play, expect roughly 60-80 hours of total game time to reach full Prestige Shop completion. The exact count depends on your active bonuses and current biome drop rate, but the baseline range is consistent.
Does the second rebirth unlock anything special beyond the Prestige Shop?
Yes, the second rebirth unlocks the Astral Annihilator drill recipe at the crafting bench, which is the highest-tier drill in the game. It also unlocks the Void planet, which is the end-game grind location for the rarest materials in Mine a Planet.
Common Mistakes That Delay Your First Rebirth
The most common mistake is to grind ore indefinitely after reaching level 25, because the level cap for Prestige Point math tops out around level 50 and additional ore past that point contributes almost nothing to the rebirth payout. Players who delay their first rebirth to grind 10 million extra Drill Pieces typically lose more than they gain, because the Prestige Points they could have earned at the optimal rebirth moment would have multiplied their subsequent runs far more efficiently.
The second mistake is to rebirth without binding a Legendary drill, which throws away the largest Prestige Point multiplier in the system. The third mistake is to bind a drill that has not been reforged for high Ore Multiplier, which weakens both the immediate Prestige Point payout and the long-term value of the bind. Always bind a reforged Legendary, never a stock one.
A practical way to avoid all three mistakes is to set a hard rule for yourself: the moment you craft a Legendary drill with a high Ore Multiplier reforge, trigger the rebirth within the same session. Do not log off to "think about it" — the temptation to grind one more batch will almost always cost you more than the Prestige Points you would have earned by resetting immediately.
