I revived mine at an obelisk and they are pretty scary to tame tbh. Had to bring 2 bug repellants one for my argy that i left behind a rock in case i aggroed the arthro and had to run. Idk about it in caves but if revived they will move around unpredictably while taming. Approach it from the side to feed it, its feeding hitbox only works on its upper half so you cant feed it from the tail but going for the head is also pretty bad because when it moves again its probably going to touch you and start attacking
All you have to do is tame a scorpion and ride up to an arthro on the scorpion and feed it spoiled meat. The arthro will not aggro on you while you are riding the scorpion. I did this on my mobile world so I can confirm that this works at least on mobile.
Easiest and safest way to tame this is to lure it under water. They stop aggro and you can tame as you please. Just make sure you come up for air every once in a while. Also be sure the water is deep enough.
