In the Roblox incremental game +1 Assassin Leveling (developed by +1 on top), rebirthing is the primary system for scaling your character past power walls. Reaching designated level milestones allows you to execute a rebirth, which resets your current level in exchange for permanent Strength multipliers and access to upgraded training zones.
Because enemy health jumps rapidly across World 1—scaling from early goblins up into the billions and trillions by Stage 18—regular rebirths are required to reach the Strength necessary to progress.
How Rebirth Works in +1 Assassin Leveling
The rebirth button becomes active whenever you reach the level requirement for your next tier. Clicking the rebirth button resets your character level back to the start of the training curve, but your gear, currency, pets, and unlocked stages remain intact.
Rebirthing provides two distinct progression benefits:
- Permanent Strength Multipliers: Every rebirth increases the base Strength gained from manual clicks and slashes. Early rebirths scale your power by 2x to 5x, while higher tiers eventually provide massive multi-thousand-point multipliers.
- Training Treadmill Unlocks: The training area in World 1 contains progressive training stations (treadmills). Each station is locked behind a minimum rebirth milestone, offering exponentially higher Strength per slash than base clicking.
Observed Rebirth Milestones and Requirements
In gameplay recordings, level requirements scale upward with each tier. The table below lists the verified level targets, rebirth counts, and associated zone unlocks documented in player playthroughs.
| Rebirth Tier | Observed Level Requirement | Verified Multiplier / Unlock | Source |
|---|---|---|---|
| Rebirth 1 | Unspecified early level | Initial Strength multiplier increase | Recorded gameplay |
| Rebirth 2 | Level 25 | Strength growth scaling | Recorded gameplay |
| Rebirth 3–4 | Levels ~40–50 | Incremental Strength scaling | Recorded gameplay |
| Rebirth 5 | Level 52 | 5x Strength multiplier; unlocks 5x training treadmill | Recorded gameplay |
| Rebirth 6–8 | Levels 70–100 | Multiplier increases up to 8x Strength per slash | Recorded gameplay |
| Rebirth 9 | Level 125 | Unlocks Tier 9 training station (8x+ Strength output) | Recorded gameplay |
| Rebirth 11 | Level ~150–175 | 3.5x+ Strength scaling jump | Recorded gameplay |
| Rebirth 13–14 | Level ~175+ | Unlocks Tier 14 training station (11x multiplier, ~3M Strength/slash) | Recorded gameplay |
| Rebirth 16 | Level ~266 | High-tier flat Strength progression | Recorded gameplay |
| Rebirth 27+ | Level 400+ | High-end scaling (+2K Strength multiplier jump documented at Rebirth 30) | Recorded gameplay |
Note: Specific level requirements between minor intermediate tiers may fluctuate slightly depending on active quest completions or version adjustments, but the training zone gates (such as Rebirth 5, 9, and 14) remain rigid progression checks.
When Should You Rebirth?
Because level accumulation accelerates as your Strength grows, rebirthing as soon as the prompt appears is generally the most efficient path. However, there are two gameplay situations where delaying a rebirth is optimal:
1. Active Quest Boost Windows
Quests frequently grant temporary boost timers, such as double Strength (2x) for durations ranging from 2 minutes to 20 minutes. If you have an active 2x boost running, remain on your current highest training station and farm raw Strength until the timer expires. Rebirthing during a short boost window wastes valuable seconds re-leveling through the early stages.
2. Pushing for Imminent Stage Boss Wins
If your current Strength is already sufficient to clear an upcoming stage boss (for example, breaking through Stage 6 or Stage 12 to collect 2.5K to 10K Wins), clear the waves and defeat the boss first. Bosses award Wins and item drops, which you need to buy daggers and auras. Once you secure the currency or hit a combat wall that you cannot beat, trigger your rebirth.
Maximizing Strength Gains Between Rebirths
Reaching higher rebirth levels quickly requires stacking every available multiplier before stepping onto the training treadmills.
Utilize Higher-Tier Treadmills Immediately
Do not train in the starter area once you qualify for a higher station. At Rebirth 5, moving to the 5x treadmill yields significantly faster level progression. At Rebirth 14, the 11x station provides up to 3 million Strength per hit, allowing you to breeze from Level 1 to Level 200+ in minutes.
Equip Multiplier Pets
Hatch eggs obtained from the post-tutorial shop or quest rewards. Starter pets like Frogs provide basic multipliers, while rarer hatch drops (such as the Evil Unicorn or Epic Dragon) offer 4x to 8x multipliers that apply directly to all Strength gained while clicking or training.
Stack Friend Boosts
According to official game specifications from developer +1 on top, playing in a server alongside friends grants a flat +10% Strength bonus per friend. Having two friends in your session adds +20%, and three adds +30%, with no maximum cap officially documented.
Upgrade Auras and Weapons
Wins earned from clearing stages should be reinvested into better weapons (such as Royal Blades, Infernal Eye, Soul Eater, or Thunder Strike) and Auras (such as Blue Aura for 25 Wins, Gold Aura for 2.5K Wins, or Angelic Aura for 500K). These items raise your combat damage and click scaling, accelerating your wave clears to meet stage requirements.
Frequently Asked Questions
Do I lose my pets, weapons, or auras when I rebirth?
No. Recorded gameplay confirms that weapons, equipped auras, inventory items, and pets carry over through all rebirths. Only your temporary character level resets.
How many stages must I clear in World 1?
World 1 consists of 18 total combat stages. Defeating the boss on Stage 18 unlocks access to World 2.
What should I do if my damage stalls on a wave?
If your attacks are not clearing enemies or a boss defeats you, your raw Strength or dagger tier is below the stage requirement. Step back to your highest unlocked training station, rebirth if you have met the level requirement to upgrade your multiplier, and purchase the next available dagger from the shop.
