Minerva ( boss ) Minerva is an optional superboss in " Crisis Core - Final Fantasy VII - " , and is the most powerful boss in the game . Battle . Minerva is at level 100 and has 10 , 000 , 000 HP and 999 , 999 MP . She uses non - elemental attacks , the strongest being Judgment Arrow , an attack with animations resembling that of a summon . Her special move is Judgment Arrow that greatly depletes the player ' s HP , takes away their MP and AP and nullifies buffs ( including Raise ) . Minerva uses an attack called Krysta that can be dodged , but it requires perfect timing or the Dash Materia . Once she is defeated , the player obtains the accessory Divine Slayer , which increases HP , MP , and AP by + 100 % , and increase all stats + 50 , breaks the HP , MP , AP , and Damage limits , and gives Auto - Libra . The player can repeat the battle even after she is defeated . Strategy . Zack will need to be able to break the damage limit . The battle should not be entered without a Costly Punch Materia , which will deal a maximum of 99 , 999 damage ( if the player only uses Costly Punch it will take 101 hits to win ) , a Full Cure / Curaga Materia , a Phoenix Down , a lot of Elixir , Soma , and Ether items . It would be recommended that as soon as the player sees Judgment Arrow , they switch to Ether , and select it so that Zack can restore his MP and use Full Cure . It is also advised to have Zack equipped with a Phoenix Down , and if he uses that one , mug more from Minerva . It is not worth equipping a Libra because Minerva ' s HP and MP are hidden due to being so high . The player should be aware of the attacks that Minerva throws at Zack and guard only if dodge roll is not possible . Player should always aim to interrupt the Ultima casting , and not spam Costly Punch . The player should not recklessly press on Costly Punch , because it won ' t make Zack ' s attacks come any faster , and he might need to switch to dodge roll or guard . If Zack has under 3 / 4 of his max HP , the player should be prepared to heal directly after Minerva uses Krysta . Minerva also uses a slow - moving but high - damaging homing attack called Crimson Flare . It is possible to avoid this attack by running , but if it hits it will do serious damage . Even with a full set of Genji equipment , Ziedrich , and Materia with high stat boosts , this fight can be very difficult . Equipping the SP Master is highly recommended as it will reduce the damage and increase damage considerably ( approximately doubles Zack ' s damage output and reduces damage taken to 0 , if mastered ) by spending SP points . A good equipment setup is Ziedrich , Genji Armor , Genji Gloves , and Genji Shield or Protect Ring and Materia that increases Strength , Vitality , Spirit , and HP to the maximum . With the stats and equipment , if Zack guards , her attacks will cause between 100 and 7 , 000 damage . One should be sure to have at least 20 million SP . To have a large amount of SP or money , one can mug 99 Phoenix Downs from Minerva and sell them , then buy a lot of Dualcast Materia and convert to SP . An alternate and easier method is using Materia Fusion and the 99 Phoenix Downs to create a Curaga Materia with + 999 HP stat ( Curaga + Libra + Fat Chocobo Feather to convert the attached stat to HP and then Curaga + Libra + 99 Phoenix Downs to max out the HP stat ) and then converting it to SP . This Curaga Materia takes approximately 1 million SP to make but when converted , grants 2 million SP . ( These strategies will not work with the game ' s Japanese version since once a mission is lost it will be Game Over ) . The Dualcast Materia can be bought from the Net Shop Shade .
