I was the swamp cave encountered two of them i was my bary my bary was lvl 143 375+ mele 2600 hp they were lvl 300+ i killed one off them and ended up run home with the artifact long story short when you encounter two or more in a cave especially the swamp cave run home don't fight them cuz your dino will die

Killed the spider boss with this handy boys

You And put it on aggressive, and it will become a living turret

They take tripled damage from weapons like longnecks, don’t use melee or whatever ur using will get destroyed. Get out ur longneck and aim for its head, 1 or 2 shots should do it

PSA (public service announcement) that arthros have NO WEIGHT, hear that? NO WEIGHT. But on mobile this is easily counter-balanced by making it the land Itchysaurus so that means cave creatures and literally anything else just don't care about you, even if u hit them lol

One of the best raiding dino's on the island, if not the best. It can destroy any material.

Make sure you don't wear armor around them

Because they will destroy it. Use bug repellent so they don't automatically attack you. If you need spoiled meat make sure you have each raw meat split up individually that way once 5 mins passes by it all spoils at once

By the way, they are on mobile, unfortunately

I recently constructed a 1x8 pen with walls in ARK Ascended, and I found an effective way to tame an Arthro. I used my Argent 🦅 to transport it inside the pen. After placing it in the enclosure, I patiently waited, and the Arthro naturally turned about 90 degrees, which caused it to become stuck. This allowed me to easily tame it using spoiled meat from a spot near the back end of the Arthro, right along the edge of the wall. This method proved to be a straightforward approach, eliminating the need to create bug repellent or worry about potential attacks. Overall, it was a simple and effective trap design!

Arrows do an INCREDIBLE amount of damage, so use those instead of letting it destroy your melee weapons!!! 🗡🏹

Cheat The yeti cave on mobile by doing it on an arthro, almost nothing attacks them

Good luck

Go in a cave with water if they are under water you can tame without them agroin you just use a scuba tank

I will make a list of pros and cons about this creature:

Pros:

Nothing, and I mean NOTHING will aggro to you, even if you attack it

Inflicts torpor

Can melt armor, harvest dead bodies from afar with acid ball

Swims the same speed as walk

Cons:

Terrible weight (100) you're going to have to stuff your whole inventory somewhere, and maybe even your armor

Saddle requires 35 obsidian

Something I've noticed:

Wild ones can deal constant (like .5 sec between attacks) damage to you, but tamed ones, not even mounted ones can, and I get this needs to be balanced, but make it only work on wild creatures or something, I would love to see it work

Does anybody know where to find these on ark mobile i would like one for protection when scouting and i havent found any yet.

Don't attack with sword or it broken soon

It's can destroy tek walls. useful for tek raids

I find the best way to knock these out and tame them is to simply lead them into the water and grapple to them and they instantly de-aggro and it’s just a matter of feeding it. It has worked many times. Also no ghillie or bug repellent required 👍

They actually don't deal torpor with their mouth.

Lol the mr. wick and dog story got me. Anyways back to all seriousness unless u have armor and a sword or guns DO NOT ENGAGE. This beast will knock u out in like 1 bite and kills in like 3 or 4

Remember these guys can melt through your armor! try to avoid fighting them one on one or attempt to shoot it from far away.
