You can create materia, which are special little crystal orbs that contain magicite that provide a magical effect when affixed to a weapon, shield, or suit of armor.
Prerequisite(s): Caster level 5th.
You can create a materia of one of the five types: Spell, Support, Independent, Ability, or Summon (See the Materia section for more details on what you can make for materia). Creating a materia takes 1 day for every 1,000 gil in the materia’s price (half the price of a L1 materia). When you create a Spell, Support, or Summon materia, you set the caster level, which must be sufficient to cast the spell (L1 materia) in question and no higher than your own level. To craft materia, you must use up raw materials costing one-half of its base price. All non-common new materia begins its life at level 0 and 0 MXP while common materia begins at level 1.
