Volcano island on Fjordur has dead Deathworms which can be harvested use hatched for a crap ton up if useful

If your on rag I would recommend farming deathworm horns in the iceworm queen cave. The deathworms are super easy to kill and spawn way more frequently unlike the big ones that spawn in the desert.

Take a good baryonyx in a cryo to iceworm and deathworm horns are ez

A normal Deathworm drops 1 horn and the ice worm queen on rag drops 20.

Bug raged Megatheriums work really good as well.

On fjordur on the volcano island there is dead death worms and hitting them with a hachet gives a bunch of horns

If you are on rag just go in the ice cave then farm all the death worn horns in the world plus they are super easy to kill

LoL it looks like a woolly mammoth horn ahhhhhhhhhhhhhhhhh just do it ark

Make da recipe

If ur looking for death worm horns got to the snow biome on rag and look for a cave make sure u have really strong creatures and you'll kill all the death worms you'll need
