The Defiler is a minor hero that can be deployed by land to corrupt worlds and sabotage enemy structures on a planet. In combat, Defilers prefer long-range combat and creating large explosions.
For those looking to attack a planet with stealth, building a team of Defilers and sending them in to sabotage structures is a viable tactic. Defiler's blaster carbines are much like the Rebel Infiltrators. They can take down Stormtroopers and Rebel Troopers in one shot.
