[[File:rebirth.jpg|frame|A player about to Rebirth.]]
'''Rebirth''' is a mechanic in ''Phantasy Star Portable 2 Infinity'' that allows the player to keep progressing beyond the normal level cap of 200 and bolster their character up even more. Rebirth resets the character's level to 1 in exchange for permanently increased [[stats]], [[Extend Code]]s and an increased [[Type]] level cap.
The character itself is not reset, so parameters such as name, sex or race cannot be changed using this feature, nor will any other progress, such as mission or story progress, be lost.
Rebirth confers the following bonuses upon the character:
* After the character's first Rebirth, all Types will gain an extra 4 [[ability]] slots. Subsequent Rebirths will not grant more ability slots.
* Rebirth Points can be allocated to permanently improve stats or gain Extend Codes, to a limit.
* The character's Type level cap will be increased, to a limit.
Rebirth is accessed from the [[Type Counter]] in story mode once the player is at least character level 50. Once Rebirth has been chosen, the player must choose what stats they would like to increase for their next playthrough, and then will be asked to confirm their choices before finally rebirthing.
The amount of points that can be allocated to stat increases depends on the player's character level, with only 5 points being accessible at level 50, and up to 600 points at level 200.
Rebirth allows the player to increase their Type level caps. Originally, a player can only level their Types to a maximum of level 30, however through Rebirth, a maximum type level of 50 can be achieved. The level cap increase will apply to all Types on the character, not only the one currently selected when performing Rebirth.
The level cap increase amount depends on what character level the player rebirths at, however the type level cap increases are additive, meaning that rebirthing twice at character level 50 will allow the player to level all their Types to level 32.

Rebirth points are the primary currency obtained from Rebirth, and allow the player to increase the following stats:
HP, PP, ATK, DEF, ACC, EVA, TEC, MND, STA, and Extend Codes.
Each stat has a limit to which they can be increased, and each increase is persistent across Rebirths. The cost of each stat increase varies from stat to stat, and the cost increases every time a stat is increased. Each stat can be increased a total of 10 times.
There is no total limit to Extend Codes, but only 10 can be obtained per Rebirth.
Below is a table showing how much each stat will be increased by, how many points it costs to increase them, and the limit that a stat can be increased by.
Amount of Rebirths to cap
To max out all rebirth bonuses, it is required that the player Rebirths multiple times to gain the 3,080 points necessary. Below are some example paths:
* 5x 200 Rebirths + 1x 109 Rebirth = 3,082 points (508,815,015 EXP)
* 12x 150 Rebirths + 1x 139 Rebirth = 3,081 points (434,187,940 EXP)
* 51x 100 Rebirths + 1x 76 Rebirth = 3,080 points (305,630,560 EXP)
* 616x 50 Rebirths = 3,080 points (225,985,760 EXP)
While it would appear to be more efficient to rebirth at a lower level, this is not recommended as [[experience]] from [[creatures]] raises exponentially at higher levels, and the player would not be able to play higher difficulty [[missions]] or earn [[titles]] doing multiple level 50 rebirths, which they may find extremely boring to do.
The recommended level to rebirth for the first time is at level 50, however. The extra 4 ability slots obtained from the first rebirth should be obtained as soon as possible, and level 50 is very quick to get back to, meaning the player does not have to do an extended levelling focus early on in their progression. After this, players should rebirth at level 200, as that grants the best time/point ratio factoring in the increased experience that can be obtained at higher levels, especially in [[The Magashi Plan]].
The most efficient path for maxing all rebirth bonuses is to rebirth for the first time at level 109, then do the subsequent 5 Rebirths at level 200. While this is the most efficient route to a maxed out character, a new player may find rebirthing at level 109 discouraging, as they will have only made it to S-Rank difficulty and then have to suddenly level all over again, so this is only recommended for veteran players.
However, a player can choose to rebirth whenever they want, there are no direct penalties for rebirthing when the player wishes to do so, as eventually all stats will be maxed.
Below is a table listing the amount of rebirth points that the player obtains at each character level.
