I met this in a dungeon it is lvl 700 it just spit acid to me, it break my ascendant armor and died,it one bit me, if you encounter this in dungeon, make sure you have a ascendant compound bow to kill this thing, you need to be fast, just hit and run, easy as that
DO NOT ENGAGE OR YOU WILL DIE! I was hunting araneos when this thing came out of nowhere and three shot me! All my dimorphs were literally devoured when I came back. It is like centipedes in real life but instead of killing you slowly with poison it kills you with bites quickly. Do not equip anything lower than Chitin or you will get one shot. Make the up arrow green so people can know 🙏🏻
These guys will break your armour very quickly, so when going in a cave, make sure you enter on a mount (if you can) and wear hide armour. Then, bring some fiber with you. You will be able to get hide in the cave, so when these guys break your armour, you can repair it quickly.
If you plan on building in a cave, build at least 2 layers worth of walls of the material of your choice (the stronger the better). I built in a cave once, I logged in it was fine, I took my raptor out for some meat for my feeding troughs and when I got back, I saw one of these dudes eating my wall. My tames killed it but I had to fix that gap. So if you are planning on building in a cave. Have more than one wall dividing you and the killer centipedes. Or do the the therizinosuarus tips and do the bounce spike wall I mentioned. Never failed me.
