Terror of the Deep weaknesses, resistances, and immunities

Terror of the Deep is weak to Lightning in Final Fantasy 7 Rebirth. You should have at least one Thunder Materia equipped on a character. It’s better if this is equipped on the party leader, so you can use it as many times as possible. Another great way to inflict Lightning damage on Terror of the Deep is to summon Ramuh. This is just one of the summons you can get over your journey in FF7R.

Avoid using Fire or Ice, since it’s resistant to those two. It also won’t be easy to inflict any debuff, like Stop, Petrify, Slow, Silence, Sleep, and Stone, since it’s either resistant or immune to them altogether.

Best team versus Terror of the Deep

The best team to beat Terror of the Deep in Final Fantasy 7 Rebirth are Cloud, Aerith, and Barret.

  • Cloud can deal melee damage with the Aerial Combo (press circle and hold square for the gap-closer).
  • Barret can deal continuous ranged damage when Terror of the Deep is out of reach.
  • Aerith can provide support while buffing spells with the Radiant Ward

Phase one

To beat Terror of the Deep in Final Fantasy 7 Rebirth, be aware of its moveset and react accordingly. Its attacks can incapacitate your party members, causing you to waste one ATB Gauge charge to save them each time. You can counter its strategy by either perfecting your dodges when Water Cell and Grasping Tail strike, or by keeping your ATB Gauges charged at all times so you won’t have to waste a spell saving a party member.

The best way to keep your ATB Gauge filled is to keep Cloud as the party leader and engage Terror of the Deep with an Aerial Combo. To fight in the air, press circle and hold square. This triggers Cloud’s gap closer and lets you unleash continuous damage while airborne.

Once you’ve got two stacks of ATB, create a Radiant Ward with Aerith. Radiant Ward doubles the spells you cast as long as you’re inside it. So, if you stand inside the Radiant Seal with Cloud and cast Thunder, you’ll be casting two lightning-based spells for the cost of one.

Keep at it until you reduce Terror of the Deep’s health pool to 50 percent.

Phase two

During phase two, Terror of the Deep swims in the water and sticks its head out of the holes in the arena. There is one hole in every cardinal direction (north, south, east, and west). If you locate them, you’ll know where the boss will emerge next, which gives you the upper hand in battle.

When Terror of the Deep is using Water Jet, Oceanic Tornado, or Aquatic Twister, focus on dodging any incoming damage. Once it’s used those abilities, use your gap-closer to get close and deal as much damage as you possibly can to stagger it.

Once you’ve defeated Terror of the Deep, you’ll have one less FF7R trophy to worry about.
