Gravity materia is a 
Magic Materia in Final Fantasy VII Rebirth that provides the user with gravity spells. These spells deal proportional damage based on an enemy's maximum HP. As such, the damage dealt is not based on the user's 
Magic Attack attribute, but rather on if an enemy has any resistance to gravity damage.
Obtained[]
A gravity materia is developed by Chadley for 15 Corel Region data points.

Use[]
Gravity materia grants three tiers of gravity-based spells. The spells are guaranteed to hit and deal damage based on the percentage of an enemy's HP, as opposed to any attributes that the caster has. As such, casting this will come down to the caster's MP pool, and if an enemy has any resistance to gravity-based damage; most tough enemies are immune to proportional damage.
Gravity materia has few possible 
Support Materia. Namely, it cannot be paired with HP Absorption Materia or MP Absorption Materia. However, it can be paired with Magic Efficiency Materia, Magnify Materia, Level Boost Materia, Auto-Cast Materia, and Synergy Materia. Synergy in particular can be a strong pairing, as synergy means the spell costs no MP or ATB to use, while magnify can be used to allow the spell to hit multiple enemies at once.
