Lariat

Lariat (, Lariat) is one of 's physical s in Xenoblade Chronicles. It is a wide swing that damages all enemies in front, providing talent gauge for every hit.

Overview
Lariat is very similar to War Swing in that it hits a lot of things and generates extra talent gauge per enemy hit. Which is better depends on the situation; Lariat can be used more frequently, has a longer but narrower range, and generates less gauge per enemy but doesn't stop if a hit is blocked. It also does more damage by itself, so it's a bit less wasteful to use when Reyn already has his talent gauge full. Reyn probably does not need to have both War Swing and Lariat equipped at the same time.
