    • 40%/20% HP
      • Blackout
      • Dark Messenger
      • Ends turn
  • If hit with a dark element attack, above 50% HP, uses one of the following:
    • Evil Mood1 (16.1%)
    • Evil Mood2 (28.7%)
    • Evil Mood3 (33.6%)
    • Does nothing (21.6%)
  • Under 50% HP:
    • Every 2 turns, uses one of the following:
      • Evil Mood1 (16.1%)
      • Evil Mood2 (28.7%)
      • Evil Mood3 (33.6%)
      • Does nothing (21.6%)
    • Every 4 turns: Dark Barrier
  • Remaining attacks follow a 2-turn rotation:
Turn 1, 3, 5, etc. Turn 2, 4, 6, etc.
* 3x Shadow Strike (50%) or Death
* 2x Night Terror
* Shadow Impact
* (above 60% HP) Every 3 turns: Demonic Trial

* (above 60% HP) Every 2 turns: Ruinous Omen
* (under 60% HP) Ruinous Omen

  • See testimonials and discussions.
  • Bring death resist via Safety Bit or Genji Shield on a provoke tank
  • Bring a source of blind, paralysis and stop immunity.
  • Gear your team with dark resistance, or bring a magic cover tank with 200% (innate + buffs) dark resistance.
  • Gravity, Graviga, Death and Bioga can be reflected, or sealed with Manufacted Nethicite, Sealing Blade and Silence
  • The Graviga attack can be best dealt with in the following ways:
    • Using a source of reflect will allow you to avoid its damage.
    • Defending with your magic cover tank (on the 80% and 60% HP threshold) helps it to survive while covering Graviga.
    • Cast one of the following abilities: Manufacted Nethicite, Sealing Blade from Celes or Silence from Rena.
  • Veritas of the Light has passive demon killers and light imperil, equipping her with Diabolos and chaining with a dupe will bring down Diabolos easily.
    • Any magical chainer can bring down Diabolos easily. Protect the party against the threshold.
  • Diabolos has much lower SPR than DEF. Magic damage chains (Tornado+Aeroja) or even Lila will trivialise this trial.
  • Since Veritas of the Dark can absorb dark attacks, if geared for evasion with death resist, a source of Demon Killer, enough mp recovery to use Dual Slash constantly, then he can mostly solo. A light element weapon will make it go slightly faster. Bring a couple units that have a Hide-type skill, can Raise DV should he get stopped, and to summon Carbuncle.
