Honestly the easiest artifact to acquire. As soon as you unlock a bow, you can easily go on foot. Bring at least 40 arrows. When you get to the cliff bit, look for any spiders or scorpions or titanoboas, and shoot them to lure them to you. When you kill them, check their inventories for extra arrows. The final room can be accessed by crouching, get in, grab the artifact, get out, no time wasted!
