Servans are fiends that fight alongside their master during hunt.
Nights of AzureEdit
Servan make contract with Arnice by actualizing Fetish. After making blood contracts and give them a name, Servans are summoned and helps out during Arnice's fiend hunting. Arnice can summon up to four Servans to her battles. Each of them come with different forms, abilities and types; namely Defender, Tricky, Support, Attacker, Follower and Magic type. These Servans level up by defeating fiends. As they level up, they can for example: change colors, increase size, increase in numbers, increase their stats or learn abilities.
They also possess a special ability called "Servan Burst", which consumes SP and varies from dealing damage to enemies, heal allies or boost allies' stats. Servans reside in Ende Hotel, and that's where Arnice can switch between different Servans, equip accessories to them or simply check them up.
The Servan can be discarded from the party permanently by sent them to oblivion. The sole exception was Gust due to her status as DLC.
Nights of Azure 2: Bride of the New MoonEdit
Fetishes has been omitted and it's no longer possible to actualize Servans, as well as cannot equip accessories to them. Instead, Servans can be recruited to Aluche's party by finding them in their specific locations and releasing them from wicked flowers, or completing side quests (in case for Kaede and Alice).
Aluche can take up only two Servans to her hunt. There are two types of Servan, each with their own special actions. Trickers are capable of opening the path forward, while Strikers can turn into weapons that Aluche can equip.
Servan Growth can be done at the Maintenance Room. Servan Points are obtained as quest rewards and can be used to level up Servans, and they will evolve when their total level reaches 30. If the Servan raise them to their maximum level capacity, they can be reincarnated. Reincarnation reverts them back to their original status, but their level capacity will increase. Additionally, using Evolution Gems on Servan will allow them to undergo Ultimate Evolution. An ultimate evolved Servan will receive a massive ability boost. Evolution Gems are obtainable from treasure chests.
