Cuelebre

Notes:

 * 20-60 minute Timed Spawn among the Nauls at (E-9).
 * Always flies and does not mêlée.
 * Attacks appear to be earth magical damage (reduced by Saline Coat, Barstone, and Earth Carol).
 * Will take mêlée damage despite being in the air while Mighty Strikes is active.
 * Aspirable.
 * Can use Bai Wing for ~600. Additional effect Slow can proc on Bai Wing, but can be resisted with earth resist setup, Barstone and Earth Carol.
 * If you pull it down through the encampment toward Conflux #3, there is a somewhat hidden ledge where the alliance can stand without danger of getting hit by AOE if the NM is tanked further down the hill. Similar to Astral Flow in prime avatar fights.
 * Will spam Ochre Blast after using Mighty Strikes (will use it multiple times).
 * Can be avoided in the same way as Bai Wing, but you'll need to stay on a tank's HP for this part of the fight.
 * Ochre Blast does roughly 350-400 per use.
 * Can cast Slowga(overwrites Haste), Stoneskin(can dispel), and Breakga.
 * Seems to only use Breakga at low HP.
 * Does not use Draw In.
 * Has increased movement speed.
 * Unlike Ouryu, Cuelebre is susceptible to Stun. Additionally, Temporal Shift landed reliably without a Thunder Staff, even though he seems to be resistant to Thunder spells.
 * The quest Tangling with Tongue-twisters has this NM as a goal kill.
 * Appears to rage after a certain time. After about 45 minutes - 1 hour all damage was resisted for 0 damage except from Summoner BP's and Damage Over Time spells. Only by wiping and letting it regen did damage become able to be dealt again. (Possible this "rage" might be activated by "!!" Weakness.)
 * During this phase, its magical regular attacks, as well as Bai Wing and Ochre Blast receive a boost in damage, hitting for upwards of up to 300(regular), 600-800(Bai/Ochre) on a non-tank job.

Historical Background
Cuélebre, or Culebre, is a giant winged serpent-dragon of the Asturian and Cantabrian  mythology, that lives in a cave, guards treasures  and keeps xanas  as prisoners. Although they are immortal, they grow old as the time goes by and their scales become thick and impenetrable, and flag wings grow in their bodies. They don't usually move, and when they do it, it is in order to eat cattle and people. One can kill the cuélebre giving him as meal a red-hot stone or a bread full of pins. Its spit it is said to turn into a magic stone which heals many diseases.
