Quake3 deals damage in the following formula:
- $ (70 / 16) * [ (Level + Magical Attack) * 6 ] $
where "Level" is the caster's current level and "Magical Attack" is their Magic atk stat. This is effectively 4.375x the base magic damage.
Quake3 can be used by characters with the Earth Materia at level 3. Though it deals significant damage, it also has a very high MP cost, meaning it should be used sparingly and saved for boss battles. It is best used against enemies weak to Earth damage, as other spells with a similar MP cost can deal more damage. It misses against flying opponents; Final Fantasy VII does not have a "flying" state like some other entries to the series, but most flying enemies have their Earth affinity set to Immune. Usually when an element is used on an enemy that is immune it does 0 damage, but in the case of Earth it will miss. Earth will miss Earth immune enemies even if they are grounded (this also applies to when player's own characters are immune to Earth).
Quake3 can be amplified by pairing the Earth Materia with Support Materia. MP Turbo or Quadra Magic can be useful to amplify its already high damage and Magic Counter allows it to be used without using up a character's turn. Pairing it with MP Absorb also mitigates the high MP cost, while HP Absorb can grant greater endurance to the caster by healing them. All allows the spell to clear groups of enemies, though using Mega All will have the same effect and allow it more options for paired Support Materia. Quake3 has a different animation when used with All. If the character has multiple Earth Materia linked to different Support Materia, the spell can take on various effects simultaneously.
Quake3 is useful against all enemies that are weak to Earth, or that do not otherwise resist or absorb the element. It can remain among the top tier of spells, and is particularly useful if paired with the right Support Materia, but it is outclassed by other spells. This includes Break, another Earth-elemental spell granted by the Contain Materia, which has a chance to inflict Petrify.
