Uses: Auxiliary lots is a PvP unit that is commonly used in both arena and guild wars. His S2 provides attack buff and up to 100% combat readiness to a unit on your team. If your auxiliary lots is fast enough to take the first turn, you will be able to boost up a cleave/nuke unit that is on a slow, glass cannon-build, and decimate the enemy team. This is why his gear prioritizes speed and nothing else (battles using auxiliary lots are often decided won or lost within the first few turns).
