Second Wind is an ability exclusive to Ramza. The skill costs 12 MP and allows Ramza to increase by 50% one ally's ATK and MAG for the duration of three turns.
Currently, in the Global version, Second Wind is an exclusive materia that was obtainable during the Orbonne Monastery Vaults event, by purchasing it from King Mog's reward shop at the Farplane; its cost was 6000 auracite shards. In the Japanese version, however, the skill is naturally learned by "Mercenary Ramza" at Level 1 (5★), as his starting ability.
A tailwind is a wind that blows in the direction of travel of an object, while a headwind blows against the direction of travel. A tailwind increases the object's speed and reduces the time required to reach its destination, while a headwind has the opposite effect. Tailwinds and headwinds are commonly measured in relation to the speed of vehicles — commonly air and watercraft — as well as in running events — particularly sprints.
