Serra

Notes:
 * Lottery Spawn at F-9 along the western seashore from the 4 Jagil in the surf and the Kraken, approximately every 1-4 hours.
 * Around 4200HP
 * Appears to have Dragon Killer trait.
 * Killable by: 2 characters level 50+.
 * Killed also by: 52 DRG/WHM but had very low HP at the end. Safely killed it at lv 55.
 * Killed also by: 68 PLD/THF with no trouble at all, just a slightly long fight. Only had to Cure IV once.
 * Killed also by: 62 THF/NIN with some trouble, Utsusemi helped a lot, evasion gear, acid bolts, no bloody bolts, Serra took me down to critical HP, with bloody bolts i am assuming the fight would be much much easier, if getting close to death use Perfect Dodge.
 * Killed also by: 46 BLM/DRK and 46 WHM/DRG. BLM used Elemental Seal and Bind at the beginning, so the mages had no interruption while spellcasting. They had also built up their TP and used Starburst + Seraph Strike for skillchain:Impaction + magic burst with Thunder. In emergency the WHM can use Benediction and the BLM can use Manafont.

Historical Background
In Medieval folklore, the Serra is a large creature which is a combination of a fish, a lion, and a bird. It vaguely resembled a dragon, but had feathered wings and a body that was a cross of a fish and a lion. It would cause ships to sink by cutting into them with the serrated crest along its back. It appears in Philippe de Thaun's Bestiaire (1120s CE). It was apparently based on the sawfish. Serra is the Latin word meaning "saw". The Spanish word sierra is derived from serra.
