When you learn how to summon Ifrit, you get a 'new' spell: Summon III. Summon III is a melee DPS.

When you learn how to summon Titan, your Carbuncle (Topaz) is replaced by Titan, which is called by Summon II. Summon II is a tank.

When you learn how to summon Garuda, your Carbuncle (Emerald) is replaced by Garuda, which is called by Summon I. Summon I is a caster DPS.
