If you're trying to beat a Furnace Golem in Elden Ring: Shadow of the Erdtree, you likely rode down into Gravesite Plain for the first time and immediately made a beeline for the giant flaming man trudging in the distance. We all saw this brazier-headed boss in the trailer, but what it didn't show is that Furnace Golems drop the new Crystal Tears for the Flask of Wondrous Physick.
And yes, I did just say Furnace Golems plural. Just like any other field boss in Elden Ring, multiple of these melted monstrosities are wandering around the map, and some of them are even invulnerable to all your attacks—we'll get to that a little lower down the page. So, here's how to beat Furnace Golems, their invulnerable variant, as well as a list of the new Crystal Tears and where to find the golems who drop them.
There are two types of Furnace Golem in Shadow of the Erdtree that you can find wandering the expansion's various regions. The first type is fairly easy to beat; smack them in one of their legs and stagger them three times, causing them to fall over, then critical attack their face for massive damage. After that, it's just rinse and repeat.
If you're having trouble, here are a couple of hints to help you out:
Once the golem collapses to the ground, look for the face with the glowing spot on the front of its brazier and give it a good stabbing.
So you've found a Furnace Golem but smacking its legs isn't damaging it. On second look, its legs are actually bound in metal and protected. You've also tried shooting it in the face but nothing is working. The way you damage these Furnace Golems is by tossing fire pots into the top of their brazier. When you arrive at the main entrance to the Shadow Keep in Scadu Altus, you'll find the Furnace Keeper's Note by a collapsed Furnace Golem just off to your right.
This note explains that you shouldn't toss fire pots into Furnace Golems, especially not those that "produce flaming whirlwinds" which in this case is talking about the new Hefty Furnace Pot item. While regular Hefty Fire Pots will work, too, it'll only take around three Hefty Furnace Pots to kill a Furnace Golem. You can unlock the recipe from the Greater Potentate’s Cookbook (2), which is found in the Run-Down Traveler's Rest to the south along the cliff from the Abandoned Ailing Village in Gravesite Plain.
To craft one you'll need:
You'll also require a few Cracked Hefty Pots to make some. I recommend checking out the Gaol dungeons, especially Belurat Gaol to the west of the Abandoned Ailing Village across the lake.
Now you've got your pots, head back to the immortal Furnace Golem you found and look for a Spiritspring that'll let you jump onto a ledge above it. It'll make its way over to you and start swiping the ledge with its arms—this is your cue to start throwing those Hefty Fire Pots and Hefty Furnace Pots into the brazier on top of its head until it dies. Job done.
If you find yourself at the Unte Ruins in Scadu Altus, you'll discover a graveyard of Furnace Golems, including one you can kill, and a dead one that's blocking the entrance to the ruins. So how do you move it? Well, we talked about Hefty Furnace Pots earlier; you need to throw a Hefty Furnace Pot into its brazier to wake it up. If you don't have a Furnace Visage to craft one, you can grab plenty from the Furnace Golem corpses around the area.
Once you have your pot ready, use the ruins to climb up to the balcony just to the left of it and chuck it in. If you die while fighting this Furnace Golem, you'll have to wake it up again, so be careful. Beat it and you'll get the Blood-Sucking Cracked Tear. If you look behind where the golem was sitting, you'll also find the Giant Golden Arc spell in a chest, and an altar for the Stone-Sheathed Sword, but that's a whole other thing.
Since each Furnace Golem drops a Crystal Tear for the Flask of Wondrous Physick, I'll list the ones I've found below as well as their effect:
