Fast Talker

Fast Cast is a job ability exclusive to Red Mages in Final Fantasy XI. They first get fast cast at level 15 and from there it improves 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 roll in a party to buff, debuff, and/or heal party members, 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.
