Rebirth

Rebirth is the main function of the game that allows you to progress and become stronger.

Rebirthing becomes available after defeating Hyperion for the first time. Rebirthing allows your god to start over again while also updating rebirth multipliers. These are changed to those acquired from the previous run.

Most counters are reset upon rebirth, including clones, physical/skills, creations, monument levels, and monsters fought. There are a number of other things that are reset, namely Pets. However, at certain stages many of these unlock achievements which increase multipliers after rebirth, effectively "saving" some progress for after rebirth. Progress beyond these achievements is effectively lost.

Multipliers
As your god trains and fights, rebirth multiplier increases. Many factors influence the rebirth multiplier:
 * The most obvious at the start of a run will be time. Short rebirths heavily penalize your multipliers to discourage rapidly repeated GP farming. Runs of at least 1 hour provide 100% of your expected multis.
 * Between 0 minutes and 1 hour, there is an increasing scale multiplying your potential rebirth multiplier. Your rebirth multis by x2 and x3 when you pass certain time thresholds in your rebirth. At 2, 3, 4, and 5 minutes, your rebirth multis are multiplied by 3. And after 6, 8, 10, 12, 15, 30, and 60 minutes they are multiplied by 2. After 1 hour, your rebirth multipliers increase by 1% every 30 minutes. This time multiplier effect can be increased with TGSC for up to a 100% increase.
 * Achievements give a boost to your rebirth multipliers, the extent of which is calculated from your past rebirth multipliers, AACs completed, and other factors. The multipliers for each achievement are additive, e.g. 2 achievements that both give 10x have an effect of 20x, rather than 100x. The value of the achievements increases with the highest god defeated in your last rebirth. thus the higher god defeated last rebirth the higher your rebirth multiplier goes this rebirth
 * Defeating a god will multiply your god multi by 2 and increase the stat multi cap to the same amount (this means you may lose on the stats multi benefit if it can't keep up with the god multi), for a total of 4x to your rebirth multipliers.
 * Monuments and upgrades together can increase rebirth multipliers by massive amounts.
 * Pets can increase your rebirth multipliers by up to 999% (10x) with enough growth and training.
 * Pet multiplier campaigns can increase the pet rebirth multiplier even more.
