Rebirth keeps your power curve advancing in +1 Assassin Leveling. It wipes your Strength and level, but permanently multiplies the rate at which you gain Strength. With faster gains, you can move beyond the point where your previous progress had stalled.
Quick answer: Keep training until 100% appears above the Rebirth button. Then open the Rebirth menu and use the button at its bottom. This resets your Strength and level to 0 and grants the displayed multiplier.
What Rebirth changes in +1 Assassin Leveling
Your Strength and your level are tied together. Training raises Strength, which fills the level bar at the bottom of the screen and pushes you up a level. Rebirth hooks directly into that system by handing back a new, faster starting point.
When you confirm, your Strength drops to 0 and your level drops to 0. The trade for that reset is a higher Strength gain rate, set by the multiplier listed in the Rebirth menu. Because gains climb faster afterward, you rebuild toward your old peak quickly and then push past it.
| Before Rebirth | After Rebirth |
|---|---|
| Current Strength | Strength resets to 0 |
| Current level | Level resets to 0 |
| Current Strength gain rate | Gain rate rises by the menu multiplier |
Each Rebirth also opens higher-tier training zones. The faster stations, like the X3 Strength platform, let later cycles yield far more per hit. After a third Rebirth, strikes on an X3 station can produce over 3,800 Strength each, a jump that early cycles never reach.
Read the multiplier straight from the live Rebirth panel each time. Do not assume a fixed number carries over between resets, and check the panel’s reset text for anything beyond Strength and level before you confirm.
How to Rebirth in +1 Assassin Leveling
Menu wording or layout can shift with an update. If the labels in your panel differ from the path above, follow the labels in front of you.
When to Rebirth and when to wait
At 100%, Rebirth becomes available but does not happen automatically. Decide whether the displayed gain-rate boost is worth losing your Strength and level progress and returning both to 0. Compare the multiplier with the progress you would give up.
Rebirth is most worthwhile once your current cycle has slowed and the next upgrade would take a long grind to reach. At that point the faster gain rate recovers lost ground quickly and then carries you further than before. If an upgrade is nearly in reach, it is usually better to finish it first.
The need for resets grows sharply in the late game. Stage clear requirements ramp up fast, and once your Strength runs into the millions, growth flattens hard without the multipliers that Rebirth provides. Resetting periodically keeps your clear rate steady instead of letting it stall against a wall.
There is no single best Rebirth count or schedule. Each time the button lights up, check the current reward and reset text and decide based on those numbers rather than a routine. The game stays free to play throughout, and its premium elements are optional, so progress never depends on spending to reset.
