Extravehicular Gear

  • Unlike cap damage taken effects, incoming Fire damage is capped before ImageShieldNext ATK received will be ineffective for a fixed amount
    is applied.
  • The cap to incoming damage is applied after most other forms of damage reduction. For example, consider a special attack which deals 9,999,999 Fire damage to all allies:
    • If Image95% DMG CutTaking 95% less DMG
      Damage Cut reducing damage taken for all elements.
      Warning! Does not work for Plain Damage!
      is in effect, the damage is reduced to 499,999 before being reduced to 5,000.
    • If ImageDMG MitigationDMG taken is lowered by a fixed amount
      is in effect, the damage is reduced to 5,000 and then reduced by the strength of the DMG Mitigation.
    • Additionally, if a form of ImageSubstitute (All-Ally)Receives all attacks in place of allies
      (Includes all-ally attacks)
      is in effect, the substituting character takes one attack for each party member, with each attack being reduced to 5,000. In a 4-man party, this results in a total of 20,000Verification needed.
