We suggested Eikon build for Final Fantasy XVI comprises three powerful entities: Phoenix, Garuda, and Odin. The first Eikon, Phoenix, should be equipped with the abilities of Rising Flames and Flames of Rebirth. These powers provide a combination of offensive and restorative capabilities. For Garuda, we recommend utilising Gouge and importing Gigaflare from Bahamut via Skill Mastery. This setup grants both swift attacks and a devastating ultimate ability. Finally, the third slot is reserved for Odin. Opt for Gungnir and Heaven's Cloud as Odin's abilities to unleash devastating melee strikes.
