In this guide, we are going to go over the best way to kill a cave worm. Before killing one, you will need to find a cave. Caves are pretty common; there is a cave near the cliff in the starting area of the first mission. Additional caves can be found along cliffs and near the base of mountains.

These cheap structures will block any shots from the cave worm.

Cave Worm Spawn Points

Caves are pretty dark, but thankfully, cave worms glow with bioluminescence. Additionally, cave worms have specific spawn points. This means that, if a cave worm pops up and then disappears, it is guaranteed to reappear in the same spot. Once you scope out a cave and see cave worms, you will know exactly where they will appear.

It's important to keep in mind that more than one cave worm will be inside of a cave. If the cave is deep, you may find up to a dozen of these dangerous creatures.

Setting Up Your Walls

After you locate the cave worm spawn points, it's time to set up your barrier. Place a windowed variation of the wall near the entrance of the cave. To build the windowed variation, you will need to hold down 'R' and select the window appearance. This will cost no additional materials since you have already crafted the wall.

Lighting Up The Cave

To light up the cave, equip a torch and light it. When you drop the lit torch on the ground, it will stay lit, allowing you to create small light sources on the ground. This is helpful if the cave is very dark or if it is nighttime.

You can risk catching on fire if you step on the lit torch, so try to place the torch in an area that you will not walk through.

Shooting The Cave Worm

Now that you are all set up, it's time to kill the cave worm. From behind the wall, all you need to do is shoot the worm until it dies. The wall will block a majority of the poison shots from the cave worm; you can take cover behind the solid part of the wall for shots that are aimed directly at you.

After a while, the wall will start to break. When this happens, equip your hammer and hit the wall. Doing so will repair the wall, allowing you to go back to shooting.

Do Cave Worms Respawn?

Unfortunately, cave worms do respawn. A few minutes after killing a cave worm, a new one will appear. If you are exploring a cave to gather new materials, it's important to move fast so the cave worm doesn't start attacking again.

If you need to seek shelter in a cave during a severe weather event, it's advised that you stay near the entrance where cave worms cannot get to you.

That's all there is to know about killing cave worms! Once you kill a few using this method, you will start to get the hang of it, and be able to kill cave worms in no time.
