Stage Difficulty: 180 (CHAOS)
Requirements: 650k, no KO, 65 turns, less than 10,000 HP damage
The enemies resist melee and ranged, Poison and DEF Down debuff.
Wave 1:: Wyerd x2, Ice Bomb x1 (complete on turn 6)
Wave 2: Wyerd x2 (complete on turn 10)
Wave 3: Ice Bomb x1, Ice Wolf x2 (complete on turn 13)
Wave 4: Commander Beast, Worker Beast x2 (complete on turn 42)
Wave 5: Ghost Brother x3 (complete on turn 62)
I can foresee that this stage very difficult to complete without Ultimecia or 2 magic EX+ DPS.
Even though the boss resists Poison, Serah's EX framed debuff won't be negated. Serah is brought in the stage for her offensive buffs and auras (My Serah has 2 perfect cursed artifacts (Debuff All boost, Charged Moonlight)
Serah's Poison (EX), Ultimecia's (Sorceress Hatred), and Sherlotta (Sap) are very useful to negate the bosses BRV to a manageable amount.
