Rebirth is a free, repeatable multiplier. The doubling compounds: rebirth 1 = ×2, rebirth 2 = ×4, rebirth 3 = ×8, and so on up to a ×1024 cap at rebirth 10.
First rebirth resets your level but doubles your JumpPower multiplier. Free, repeatable, and stacks with every other multiplier in the game.
After 10 rebirths you hit a ×1024 ceiling. Tool 2 clamps the rebirth slider at 10 and warns about diminishing returns past that point.
