Boost an ally's Speed.
Tailwind is an ability of the Squire class, unique to Ramza only and learned for 200 JP. It increases one ally's Speed within a range of 3 and activates immediately upon being selected.
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.
