The Silver Wolf Roller is an armored vehicle that employs a giant roller to flatten the group of enemies in 3 spaces in front of it. While it is limited to attacking those in the three spaces in front of it, armored units can easily withstand its attack as well. However, it is a blocking unit and will shield much more dangerous Silver Wolves, such as the Wolf Bombadier and Wolf Devastator. The Wolf Roller made its debut appearance during the Silver Wolves Invasion event
The Silver Wolf Crusher is the strongest version of this unit. You will begin to encounter it at level 55.
