The Fate System (縁システム, Enishi shisutemu)? in Devil Survivor 2 expresses the level of friendship you have with your fellow Demon Tamers, similar to the Social Link system in Persona 3 and Persona 4. As this favor level increases, your allies will unlock new potential such as elemental resistances or new demons.
Ranks[]
In the game there are six ranks a character can have, zero through five. Each rank grants a special bonus of some sort to that character.
- Rank 1: The character gains resistance to one or more elements.
- Rank 2: The protagonist and said character can perform joint Skill Crack. If either character is targeting a skill, both teams are capable of cracking that skill once its host enemy is defeated.
- Rank 3: A special demon fusion formula is unlocked (see below).
- Rank 4: The protagonist and said character are capable of performing SDTP (Summoned Demon Transfer Protocol), where a demon on one's team can be sent to the other in the midst of battle. If that demon enters an occupied slot, the previous demon is returned to the in-battle stock.
- On the 7th Day of the Septentrione Arc, the Demon Tamers split into factions vying for the right for an audience with Polaris. The protagonist can choose to try and convince defeated and surviving members to join his cause. Only characters with Fate Rank 4 or higher will join him, with the exception of Yamato and Ronaldo, who will not join opposing causes except in Daichi's route.
- Rank 5: Another special demon fusion formula is unlocked (see below).
- The player also earns the "Confidant" title for that character.
