At FwYAeJXiwVc@01:56 the presenter says rebirth is a permanent 20% income boost and plus five max health. That is spoken over gameplay, not a tooltip screenshot. Check the panel on your plot.
At @05:44 he opens it and says it is not available yet. His read: finish the current base first. If your copy lets you prestige earlier, trust the live lock text.
A permanent 20% beats a two-minute 20k over any long session, once the lock is actually open. Do not dump an era’s Points into swords if the last evolve buttons are still grey.
Finish the row, evolve if that is the gate, then rebirth. Point cost is still unknown.
The Point cost. Whether both partners share one rebirth. How many times you can do it. Whether Greek / Cyberpunk changed the lock.
20k does not prestige you. UPD1 does not prestige you. Codes are timed income. Rebirth is a plot button.
If you just want the button order, use the how-to-rebirth guide. This page is the evidence notes behind it.
