Naofumi Iwatani’s review

  • The effect of “True Arts” can stun the enemy, which can hinder the enemy’s Arts and actions
  • If you succeed in fainting with the effect of “True Arts”, you will be dealt strong damage that ignores defense, so it will be a high damage as a defender
  • Even if you fail to stun due to the effect of “True Arts”, you can recover your own HP and increase the secret gauge
  • Improve the damage of allies while giving damage up with the effect of “Arts”, so you can increase the survival rate of allies while increasing firepower
  • Recovers from damage caused by the effect of the skill, further reduces fear (freezing, paralysis, and no interruption of attack), so the survival rate is high and the Arts is not disturbed
  • Because of the effect of the ability “Shield Hero”, the ability to nullify damage at the start of the quest will increase the survival rate against enemies shooting the opening Arts.
  • The effect of the ability “Shield hero” will reduce the damage taken when attacking with a normal attack, so the survival rate will increase greatly along with the skill
  • Effect of the ability “Disable Enhanced” will increase the defense power when the damage is invalidated, so it is very compatible with “Arts”
  • Equipped with 5 star defense and 5 star recovery frames, self-contained damage reduction and recovery
  • Because you can equip 4 star support equipment, you can also support allies
  • Available in quest missions
  • Can be used as LUCK frame
  • You can’t do any damage unless you stunned “True Arts”
  • If you want to recover with “True Arts”, you cannot recover if you faint.
