Use a five-step Rebirth readiness checklist: read the live reset warning, separate known facts from stale guide claims, verify current requirements, losses and rewards, then model recovery before confirming.
Before resetting, confirm the current requirement, losses, reward, retained progress, and next-tier access. Supersonic Jet and Spawn Tier are update-sensitive signals, not fixed requirements here.
Each step gives you a visible checkpoint before the next commitment.
Record the requirement, reset warning, retained progress, and promised benefit exactly as they appear in your server. Do this before spending Cash to chase an old screenshot or video milestone.
Useful check: If Supersonic Jet appears in player coverage but not in your panel, follow the panel.
Estimate the first reachable troop after reset, the Cash/sec needed to rebuild, and how much time the early merge chain will take. Use the calculator with a smaller target to model the first recovery stage.
Useful check: A rebirth benefit is useful only if the early loop restarts faster than before.
Use the live retain/reset list to decide whether any Cash, troops, upgrades, or Spawn Tier progress should be spent first. Do not assume everything resets or everything stays.
Useful check: Take a screenshot of the warning so you can compare the result afterward.
Compare any Supersonic Jet or Spawn Tier advice with the current panel and server. Treat older requirements, multipliers, and reward claims as stale when the live wording differs.
After rebirth, restore the income loop first, then merge toward one reachable troop and test camp readiness again. Avoid jumping straight back to the previous distant target.
The game advertises weekly updates. A number or named troop from a guide can drift even when the general rebirth system remains.
A higher multiplier does not help if you cannot fund the first useful merge chain after the reset.
Compare its current visible effect with Cash/sec and your next merge. The strongest choice depends on recovery time.
Compare your current top troop and progression state with the requirement shown in the panel. If the wording changed, use the current wording rather than an older guide.
Reduce the next troop target, restore Cash/sec, and use observed offline gains instead of the gross estimate until the new loop stabilizes.
Read the current rebirth panel. This guide does not hard-code an exact threshold because requirements can change with updates.
The current retain/reset warning is authoritative. Record it before confirming; public coverage is not consistent enough for a permanent list.
Recent player coverage links Supersonic Jet with rebirth progression, but the current in-game panel decides whether it is required in your version.
Recent guides discuss it as an upgrade that raises spawned troop tiers. Its exact effect and best timing should be read from your current game UI.
