|インフェルxネネシャ (Infel & Nenesya) (inferu crosu nenesha)|
|Description||They had appeared as Luca and Lady Cloche's Mind Guardians. Overcome by the will of the continent they crafted, they tried to return the world to nothingness. Their power is no less than that of Ryuuju.|
The final phase of Ar tonelico II: Melody of Metafalica's final battle, this time Nenesha and Infel are fighting together in order to make true their vision of the utopia. The song playing during this battle is EXEC_over.METHOD_SUBLIMATION/. ~omness chs ciel sos infel.
Given their status as final bosses, it is to be expected that they have access to the best attacks and skills possible; as well as stats. Their elemental resistances also reduce all elemental damage to the point it makes all elemental attacks insignificant, and their skills are as follows: Sword Tune and Sword Chorus both hit a single character four times; Strongest Heal, which recovers around 21000 of their HP; Twin Circler, which hits all party members seven times; Explosive Ring; which hits all party members five times; Prism Light, which hits all party members six times and may inflict the Seal status; and finally Crystalune; which hits all party member ten times.
All of these attacks are executed very quickly, which makes them have very tricky blocking timings; and Prism Light is particularly problematic due to rendering the vanguards useless due to not allowing them to use anything beyond their Lv. 1 attacks, so it is advised to heal it if it gets inflicted on anyone. At this point, there's no point to hold back, so the player should use the best items they have at their disposal if the situation gets dire; and use the best Song Magic they can, such as Ar tonelico, Phantasmagoria, Infel Phira, or Meteor Shine; in order to take down both ancient Maidens. It's also a good idea to finish the battle as fast as possible; so Strongest Heal doesn't undo all the work the player has done, and Replekia isn't advised due to cutting off the song, but it shouldn't be really necessary to use it if the player has a well-prepared party. Once they have finished this battle, they are free to relax and watch the ending.
