Fistule

Notes:

 * Does not aggro nor is it targetable.
 * Becomes aggressive and targetable after absorbing Guimauve or Bloodguzzler. Please note that the person that has hate on Guimauve while being pulled into Fistule will be the one that obtains the key item.
 * Uses an ability called Dissolve that takes HP from all surrounding targets. Took HP from Guimauve as well, not sure about other mobs. It's a Cone attack, also it's a True AoE,it will hit anyone in the area in or out of party.
 * Spawns two smaller Pustule mobs when it uses Cytokinesis.
 * After defeating one Pustule, two other spawned in it's place.
 * Pustule have increased movement speed.
 * In order to solve what the possible weakness trigger factors and conditions are, efforts are being made to centralize data capture in a standardized format. If you have some personal experience in achieving any particular weaknesss on any NM, please feel free to refer to the | Weakness Discussion segment of the Category: Abyssea Discussion tab and add your data to that form.

Historical Background
In medicine, a fistule or fistula (pl. fistulas or fistulae) is an abnormal connection or passageway between two epithelium-lined organs or vessels that normally do not connect. It is generally a disease condition, but a fistula may be surgically created for therapeutic reasons.
