Description
Jar cannon which uses explosives to fire greatbolts. Deals great damage but is slow to reload.
Experimental firearm brought to the assault on Volcano ManorGrace, where it was discovered that no one knew how to use it.
Notes
The Jar Cannon weapon can be found at the following location:
Dropped by the boss Demi-Human Queen Margot at the end of Volcano CaveGrace north of Mt. GelmirRegion. [Elden Ring Map here]
Weapon Skill: Kick

Can't be buffed by Magic or Consumables
The Jar Cannon can be upgraded by using Somber Smithing Stones.
Ammunition: Any type of Greatbolt, such as Ballista Bolt, Bone Ballista BoltBallista BoltAny type of Greatbolt, such as Ballista Bolt, Bone Ballista Bolt, Explosive Greatbolt, Lightning Greatbolt, and Rabbath's Greatbolt.
Must be two-handed to fire. This also means you effectively only need 23 Strength and 12 Dexterity to fire it.
The Jar Cannon's projectile attack benefits from the +10% damage of the Arrow's Sting Talisman, the +10% damage of the Ritual Sword Talisman, and the range bonus of the Arrow's Reach Talisman.
Golden Vow and Flame Grant Me Strength also increase the damage of bolts, with the latter enhancing Explosive Greatbolts more as they include fire damage.
You can skip the long post-firing animation by using the recoil to push you backward off a ledge. If your character falls at least from a waist-high drop, the entire post-firing animation is skipped, allowing you to reload and fire immediately. If done optimally, you can fire twice at the same time it takes to fire once normally.
