Fast Cast
From Final Fantasy Wiki
Fast Cast is a job ability exclusive to Red Mages in Final Fantasy XI. They first get fast cast at level 15 and from then on it will improve every so many levels. Fast cast has two effects, one of which is to decrease the cast time of spells. It also actually reduces the recast time between spells as well. Since a Red Mage usually has the role in a party to use Buffs, Debuffs, and/or healing, this helps them get more spells out quickly.
This is also one of the primary abilities that makes Red Mage an attractive subjob. Many other casters can benefit from quickened casting and recasting times, including Bards who's songs are effected by the fast cast ability.
Fast cast is related to the another Red Mage ability Chain Spell.
