There are tons of exciting weapons to unlock in Elden Ring and some of them are a bit more eccentric than others. Take, for example, the Jar Cannon. This massive mortar is capable of launching a huge projectile at enemies and what it lacks in speed it more than makes up for in raw power. Past all its logistical aspects, this Ballista is just plain fun to use. But getting the Jar Cannon itself can be a bit difficult for some players.
