The Silver Wolf Artillery provides the Silver Wolves with indirect fire support. It is less threatening than the Wolf Bombadier because it fires less frequently and has poorer defense and health, but the shells it lobs can still rip apart unarmored infantry and support units in the rear ranks. The Wolf Artillery made its debut appearance during the Silver Wolves Invasion.
Though it looks like an Aries (and is an Aries if you bought it and compare it), the damage is comparable to even an Earthshaker! Fortunately, they only have 1 ammo. the bombardier is a higher priority because of its lower cooldown times
The level 5 version looks like a Wolf Bombadier, but it has the Vehicle-Metal type.
The strongest version of this unit is the Silver Wolf Rainmaker that you will begin to encounter at level 55.
