UNLOCK: Capture at least one of every fiend in Mi’ihen Highroad.
BOSS ANALYSIS : Kottos doesn’t have much of an offense to give. He’ll use basic physicals throughout the whole battle, really, and always as a counterattack. That’s about it.
MAIN STRATEGY : Throw up Protect/Auto-Protect and Hastega/Auto-Haste, and simply tread carefully here. Don’t attack too much or you’ll get countered too much (Protect only halves physical damage), and be sure to heal when needed. Auto-Potion with X-Potions really ought to suffice for that here, though. Once again, Doom and Trio of 9999 are alternative strategies.
