The battle with the Dark Elf on active battle speed 1. Cid Lv21, Tellah Lv24, Cecil Lv20, Yang Lv22 Honestly, getting through the Dark Elf's cave is harder than the Dark Elf himself, so you probably won't have much trouble with the fight if you can make it to him at all. It's a good idea to buy mythril equipment for Cecil in the town of—wait for it—Mythril, which is on a tiny island south of Fabul, and just stick him out front to soak up damage. You should also pick up a few Diet Food items there since they can come in handy during the Dark Elf fight. Equip Tellah with a healing staff from Mysidia and use it to conserve MP as you go through the cave since he's your full-time healer. Also, cast Osmose on any Cave Nagas you encounter to regain MP. Yang and Cid are your damage dealers but don't give Yang a thunder claw since the bats absorb thunder damage. Once you make it to the Dark Elf himself, don't bother doing anything when you first fight him. It's a scripted battle so...
