How to Beat Jabberwock

Jabberwock Boss Fight Tips
Use Fire Attacks Against the Jabberwock All of the Jabberwock's Attacks are Blockable Have Ways to Remove or Resist Petrify

Use Fire Attacks

The Jabberwock is susceptible to Fire damage, so make sure to equip a Fire Materia on your Main DPS to exploit its weakness.

This is especially important for when it uses Gorgon Shield since dealing Fire damage is the easiest way to remove it and put the Jabeerwock under pressure.

All of Its Attacks are Blockable

Unlike most other bosses, all of Jabberwock's attacks are blockable, including the attacks that have a Petrification effect. Make sure that you have enough space to see its incoming attacks and equip the Steadfast Block and Precision Defense Focus Materias to improve your blocking.

Remove and Resist Petrify

In case you fail to block its attacks, make sure that you have a way to either resist or cure Petrification. The best way to do this is by having a Cleansing Materia equipped so you can cast Resist and Esuna on any party members afflicted with Petrification.

You can also use a Warding Materia linked to Petrify or Accessories like a Jeweled Ring or Safety Bit so that you're completely immune to Petrification, but you'll have less Materia slots to work with and a non-stat boosting accessory respectively.

Do note that you can also use Gold Needles to cure Petrification, but once you get to Hard Mode, you won't be able to use items anymore.

Jabberwock Best Party and Builds

Notice	This party setup is built for Hard Mode. If you don't have certain members, equipment, or Materia available, you could replace them with the closest alternative that you have available.

Recommended Party Setup

Recommended Party Setup
Aerith	【Main DPS】 ・Double casts spells with Arcane Ward. ・Doesn't need to dodge attacks. Recommended Level: 70
Tifa	【Stagger DPS】 ・Heavily increases stagger damage. ・Use Tifa while Aerith's casting spells. Recommended Level: 70
Cloud	【Support / Tertiary DPS】 ・Mainly casts Resist and Esuna. ・Can also be a DPS with Punisher Mode. Recommended Level: 70

Aerith Casts a Barrage of Powerful Fire Spells

With the combination of Arcane Ward and double casted Fire Spells, Aerith can quickly take down the Jabberwock. Also with ATB Ward and the ATB Assist Materia, she can rapidly fill the other party members' ATB Gauges without you needing to swap to them.

Another benefit of using Aerith is that she doesn't need to worry about her Ward placement to dodge attacks since she can just block everything.

Alternatively you could also use Yuffie for her Fire Ninjutsu and Fiery Banishment abilities so that you're not solely reliant on Fire spells.

Tifa Increases Damage Dealt During Stagger

Once the Jabberwock gets staggered, Tifa can use the combination of Rise and Fall, Omnistrike, and True Strike to massively increase the amount of damage it takes while staggered.

Combine this with Aerith's Ray of Judgement and the Jabberwock can take up to 300% extra damage while staggered.

Also, whenever Aerith is casting a spell, especially ones with a long animation like Firaga, switch to Tifa so you can maximize your team's damage output.

Cloud's a Support That Can Double as a DPS

Cloud's main role on the team is to provide support by blocking and curing Petrification with Resist and Esuna respectively. He can also be an effective DPS using Punisher Mode's counter, but make sure that you're dodging Lithic Curse and its AoE attacks since you can't counter them.

Jabberwock Best Materia to Use

Recommended Materia for Aerith

Weapon: Plumose Rod	Armor: Valkyrian Bangle
ATB Assist ATB Stagger HP Up MP Up Magic Up Steadfast Block	Magic Focus Fire Cleansing ATB Boost Assess Prayer
Summon:	Phoenix

The important Materia for this build are Magic Focus linked to Fire for your primary damage source , Cleansing in case the other party members are Petrified, and Steadfast Block to reduce the damage you blocked while also giving an ATB boost.

ATB Boost and Stagger are used to give Aerith a boost to her ATB so that she can continue to spam Fire spells while ATB Assist is great for charging up Tifa and Cloud's ATBs without you needing to swap to them.

For the flexibles slots, HP, MP, and Magic Up are all generally good stat increases while Assess is useful to check for the boss' stats. Also, Prayer is useful in case you need to quickly heal the party.

Finally, Phoenix is used because it gives her the highest Magic boost out of all the available Summons.

Recommended Materia for Tifa

Weapon: Kaiser Knuckles	Armor: Enhanced Garm Bangle
HP Up Luck Up Strength Up Skill Master ATB Stagger ATB Boost	Magnify Healing Disempowerment Enervation Steadfast Block
Summon:	Odin

ATB Stagger, Boost, and Skill Master are used so that Tifa can spam as many abilities as possible as soon as the Jabberwock gets staggered.

Magnify linked to Healing is used in case no one else has ATB Chagres to heal the party, while Disempowerment and Enervation will debuff the boss and make the fight more manageable.

For the flexible slots, HP, Luck, and Strength Up are all generally good stat increases while Steadfast Block will reduce the damage Tifa takes while also giving her an ATB boost.

Finally, Odin is used because it gives her the highest Attack boost out of all the available Summons.

Recommended Materia for Cloud

Weapon: Rune Blade	Armor: Cetran Bracer
Elemental Fire Cleansing Barrier	Magnify Healing Swiftcast Revival Magic Efficiency Reraise Time Empowerment
Summon:	Gilgamesh

Cleansing will be the most important Materia for this build because of Resist and Esuna, while Time, Empowerment, and Barrier are secondary buffs to increase the party's ATB recharge rate, offense, and defense respectively.

For the linked Materia, Magnify and Healing are used to heal the entire party in a pinch, Swiftcast and Revival to instantly revive a downed ally, and Magic Efficiency and Reraise to cast Reraise on an ally at a lower MP cost, and lastly Elemental and Fire to give his attacks Fire damage.

Finally, Gilgamesh is used to give Cloud a balanced boost to his Attack and Magic while also giving a slight boost to his HP and MP.
