Alright guys, I've found a solution to this abnormality of a deviant enemy. Have 15 or more high lvl Wyverns and a flame thrower. Worked wonders. Killed one of my dragons and ended up coming back to base with 15 more Wyverns. That Deathworm was not fun at all.
Bruh big worm is so weak ark make it stronger man this is a boss you’re joking ark guys I’m right so try lvl 87 argy on it this guy is gonna poop on your house if you don’t have bombs bruh.
