Wrong category, go to Encountering

In order to fight death worms, get a rex with around 10k health and 200% melee damage. This lets you tank it while dealing loads of damage.

Use the horns to tame mantises for mantis kibble then you can get rock golems

Since everyone else's tips are stupid. If you want to find a deathworm, you can use k mode and look underground. If a worm is nearby, you will see it's body. You can use a land mount like a thyla or a flyer like the wyvern. If flying, point the flyer downwards to make controlling easier. As for fighting it....use whatever dino you have. Rexes are great, wyverns too. Wolves are effective against the worms as well as the alpha to. If you plan to live out on the dunes in SE, be prepared to have random encounters time to time. These worms CAN destroy thatch-stone-adobe. My solution was to just use my rex army but wolves work great early game.

The absolute easiest way to fight these is with a megatherium, any level will work just make sure you have a bug buff active and you can chainsaw through even alphas with ease.

When you fight the worm make sure you use a oil jar and set it on fire when it chases you.

Megatheriums are excellent for killing them including alphas. just murder bugs around the desert and the bug killing buff will allow you to tank hits and deal loads of damage :D

It has chance to drop black pearls.That's almost the only way to obtain black pearls in scorched earth.

If you’re on ragnarok and want horns, go to the ice cave. The ice worms are easier to kill.

Have a Petra and oil jars and flame arrows when the death worm comes at you set the oil on fire and when it goes under just go to the same spot easy XP or horns

Ragnarok’s southeast desert region has them. Look around the base of the big striped mountain a lil bit up the shore. Use a rex or thyla with high stats.

Tame a 100+ megatherium and enrage is by attacking creatures that give you chitin. This will give you a damage boost and a damage resistance boost. Level up melee and you will easily be able to kill a death worm

Have a lightning wyvern with 300+ melee and 10k+hp, 4 blast and it's done.

Use Sword and a mastercraft shield. Block worm's attack, then attack it twice and put your shield up quickly for worm's next attack. Rinse lather repeat. If you get knocked back too far the sword won't hit. Maintain push towards the worm to stay close while shielding. Practice the timing. When looking for them. Go on foot. They will find you. When u see a dust circle on ground in front, put your shield up for worm's surprise attack and jus keep up the pattern I mentioned. You can it twice after every block. That's how its done on foot.

ice worms have around 1700 instead of 20000 (ragnarok)

Whatever you do, don't fight it with a rock golem. On a raid my tribe baited an enemy level 130 rock token into a level 1 death worm and the worm destroyed it.

Get a Rex with atleast 10k health and 200% melee damage. If going with a buddy, I highly recommend bringing a Yutyrannus with you. Their strength boost is very helpful in situations like these.

To tame you have to do a admin code here it is: SummonTamed Deathworm_Character_BP_C has to be exactly as showed

Not tamable, get out of this section

If you see one... RUN LIKE HELL IT WILL TEAR YOU APART!
