Renew is a Tier 2 Celestial power in the Blessed tree.
Renew was a salvage company that operated on the planet Korad during the time of the Old Republic. The corporation went bankrupt many years before the Battle of Yavin. The droid MT-7T once worked for Renew.
Renew is a priest ability learned at level 26 for those with the Holy specialization. It is a Heal over Time (HoT) spell, a strong heal and one of the more mana-efficient heals priests have available. It has slow moving threat, so it can play as a useful opening heal while the tank gains aggro or serves as a solid heal while aggro is bouncing.
Full Cure is a Magic Materia found in Cosmo Canyon after the party has Highwind. The Materia can be found in the item shop back room. Like the Ultima Materia, Full Cure must be leveled up once before it can be used. Full Cure costs 99 MP to cast and cannot be paired with an All Materia.
