Steamroll

Steamroll is a Boost Card for the Light Side hero Anakin Skywalker in DICE's Star Wars Battlefront II that can be unlocked for 1 Skill Point starting when Anakin Skywalker has been leveled up to Level 10.

Overview
There is something hidden that the game doesn't tell you about steamroll. If you manage to throw someone off the ledge, and claim it as your kill, you will instantly max out your stamina reduction. I think this happens because when you ledge someone, the void does impossibly high damage to the player so no matter the health, they will die. But if you ledge them and it counts as your kill, the steamroll card counts it as your damage, thus giving you the max amount of stamina reduction.
