Efficiently farming Zeinesis (melee/ranged classes)?

[LancerFate]

Any enemy that drops the Divulcan other than Caterdran? I really dislike farming it with the ECs Caves tend to throw up that wastes time. I noticed it went up when doing Tokyo but I don't know which enemy it is.

Forest and Dragons XQ 61-65, 21-25.

Finding the exit to the boss area in Free Field Facility is pretty easy. Look above and find the large tower with water pumping at the top and that's your exit.
