The Jar Cannon is a Ballista in Elden Ring. It carries the highest physical attack of any ballista in the game.

When to Use It

Mid game. It is found around Mt. Gelmir, which opens up past Stormveil Castle, so it arrives once a build has taken shape.

Why Players Pick It

Hardest single hit of any ranged weapon in the game: 192 physical at +0 and 672 at Somber +10, with 180 stamina damage. Its 34 Str reads brutal but is effectively 23 because it must be two-handed. Also documents a real fire-rate exploit: using the recoil to drop off a waist-high ledge skips the entire post-firing animation, letting you fire roughly twice in the time one normal shot takes. Dropped by Demi-Human Queen Margot in Volcano Cave, so it is a mid-run pickup, not an endgame one.

Upgrades

Ordinary Smithing Stones carry it all the way to +25, and because it is not a Somber weapon it will also hold a grease or a weapon buff, which is a damage source the unique blades simply do not have.

Build

It scales with nothing, so the Str 34 and Dex 12 it asks for is all the investment it wants. Any Ash of War and any affinity will sit on it, so its scaling can be re-cut towards whichever stat you are already levelling.

Notes

Jar cannon which uses explosives to fire greatbolts. Deals great damage but is slow to reload. Experimental firearm brought to the assault on Volcano Manor, where it was discovered that no one knew how to use it.
