  • See testimonials and discussions.
  • Pre-emptive attack
    • Kain's first jump targets the highest SPR unit (including Auto-Shell), and since the target is chosen before jumping, it can't be provoked, but increase targetting passive works (e.g. Draw Attacks, Yellow Balloon, Moogle Plushie).
    • This jump deals very high damage, and reraise might not work due to high hit counts. Physical evasion will work however.
  • Subsequent jumps can be provoked.
    • Provoke needs to be applied before Kain jumps into the air
    • If Kain is in the air and no provoke effects have been applied, the jump will target a random unit
  • His defense is weak. Be careful not to accidentally kill him without achieving the mission. Use LB fill rate buff to gain LB quicker.
  • He uses ST Lance (HP/MP drain), AoE dark and ice magic damage, and dispelga. Rebuff when needed.
  • Make sure to dispel Kain whenever his ATK/MAG buff is up
  • Man-Eater is useful.
  • Equip esper Fenrir to your unit gives you 50% Ice Resistance and 25% Dark Resistance
  • Liquid Metal Slime (with Moogle Plushie and Esper Golem) would be a great provoke tank given the high DEF and SPR stat to survive the initial attack on defending. Recommend casting Reraise for fail-safe measure.
