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!
