After completing the Iron Country story arc, the Sage NPC located near the inn becomes available to the player. He allows players to perform reincarnations—a special progression cycle where the player's current level is reset, and in return, the player receives a series of advantages for the next development cycle.
To perform a reincarnation, the player must reach the required level. In the initial stages of the system, the requirement is level 100. After each reincarnation, the player returns to level 21, receives an increased experience bonus, and gets 3 perk cards, from which they can choose one to build their character.


Reincarnations also determine the player's rank, which is displayed in the inventory and above the character's head. The rank consists of a letter and a serial number: D1-D3, C1-C3, B1-B3, A1-A3, and S1-S15. In total, a player can perform 30 reincarnations.
Each new letter tier increases the level requirement for the next reincarnation by 25 levels. Thus, rank D requires level 100, rank C requires level 125, and each subsequent letter tier requires 25 more levels.
The experience bonus depends on the number of reincarnations performed. In the initial stages, the player receives the highest bonus, after which it gradually decreases with each new reincarnation.
After completing a reincarnation, the player receives a set of 3 perk cards and chooses one of them. The cards are divided into three types: neutral, clan, and elemental.
One of the three cards is always neutral. The other two are generated randomly based on the player's current build.
During generation, the system analyzes the features of the previous cycle: the presence of elements, as well as active and upgraded clan abilities. Based on this data, the probability of receiving corresponding cards is increased. For example, if the player predominantly studied Fire jutsus and Uchiha clan abilities, the system increases the chance of receiving a Fire elemental card and an Uchiha clan card.
However, an increased chance does not guarantee receiving a specific card—the final choice is still made randomly within the corresponding pool.

Before final confirmation of the reincarnation, the player can preview all 3 proposed cards and decide if they fit their build.
The player can either accept the proposed set and complete the reincarnation, or perform a reroll. A reroll completely replaces the current cards while preserving their types: a neutral card is replaced only with a neutral one, a clan card with a clan one, and an elemental card with an elemental one.
The cost of each subsequent reroll within a single reincarnation increases. After the reincarnation is completed, the reroll costs are reset.
The acquired card can be further modified using the reforging system. To do this, the player selects one specific card, after which it is replaced with 2 cards of the same type and 1 additional random card.
Reforging requires a special resource—a Reforging Sphere. This resource limits the number of available reforges and prevents endless build optimization.
