How to Get the Jar Cannon in Elden Ring

Do you want to blow your enemies up from hundreds of meters away in Elden Ring? Yes? Then do I have good news for you! We’re discussing how to find the Jar Cannon, a literal handheld cannon that can fire giant, explosive bolts accurately from farther than you would ever expect.

Where to Find the Jar Cannon in Elden Ring

To find the Jar Cannon in Elden Ring, go to the Mt. Gelmir region in the northwesternmost portion of the Lands Between and defeat the Volcano Cave boss.

How to Reach the Volcano Cave Boss

From the Altus Plateau, head northwest until you reach the First Mt. Gelmir Campsite Site of Grace. Continue northward past a group of dead, yellow-clad soldiers across the rocky bridge leading northwest until you reach a pair of ladders, one on your left, one on your right. After taking the right ladder, keep ascending past the Grafted Scion until there are no more ladders. Look to your right to see some Demi-Human enemies.

Proceed toward the Demi-Humans, and you’ll come upon a cave on your left leading into the mountainside. This is the Volcano Cave and a boss at the bottom awards the Jar Cannon.

Volcano Cave Boss Location

To reach the Volcano Cave boss, keep right as you move through the cave, drop down when there’s a drop-down, and continue past the larger Demi-Human through the fog until you can fight the Demi-Human Queen Margot. No, not Morgott, not Margit. Margot. It’s different. Blame Miyazaki and George R.R. Martin. In any event, defeating Margot awards the Jar Cannon, so let’s briefly review her fight.

How to Beat Demi-Human Queen Margot in Elden Ring

Margot has two phases. She’s unique in that her phase shift happens after she’s lost one-fifth of her health. In her first phase, she only has three attacks: a single slam, a three-hit bite combo, and a slam followed by a drag. You can avoid both the slam and slam-drag by rolling backward or to the sides. Her three-bite combo is trickier because the first two hits combo if you get hit by the first one.

After losing about one-fifth of her health, Margot throws her staff, roars, and goes feral. Her attacks in this phase are much faster, cover a lot more ground, and deal more damage. You must watch out for her jumping pounce, as it lets her clear the entire arena in a single jump. It hit me more times than I’d like to admit in my fights.

If you see Margot go up on her haunches and raise her front claws up, roll or run away quickly. That’s her grab attack that removed 50-60% of the health for my Level 200 character with 60 Vigor. She also has a two-bite combo and a two-swipe combo with her front claws. Both are fairly quick, but you can outpace them or roll backward to avoid them.

The one saving grace of the Demi-Human Queen Margot fight is her small health pool. She can dish out damage, but she can’t really take too much. Even a Level 90 build with +20 weapons can quickly deal with her. As soon as she falls and you get the Enemy Felled message, you’ll automatically have the Jar Cannon in your inventory.

How to Use the Jar Cannon in Elden Ring

You need at least 27 Strength and 12 Dexterity to use the Jar Cannon. You must two-hand the Jar Cannon to fire it. It has no attribute scaling, so the damage it deals is consistent regardless of your build. The only difference is in the distance the ammo travels. Explosive Greatbolts are the shorter-ranged of the two, with Lighting Greatbolts flying at least double the distance before they begin to arc downward.

The Jar Cannon is more of a PvP weapon than a PvE one, but you can use it effectively. In PvP, especially as an invader, you can use it to pester your enemies from a distance and still do a ton of damage. In PvE, the Jar Cannon’s main use is dealing with enemies at range, damaging bosses from a cheese spot, or generally harassing mobs from a safe vantage point. You could also use it for a stylish boss kill, but I don’t really recommend it if you want to survive.

Now you know not only where to find and how to use the Jar Cannon in Elden Ring, but also how to the boss that rewards it. For tons more content on FromSoftware’s latest masterpiece, check out our Elden Ring guides hub.
