This artifact is easy. I recommend taming a high level baryonyx like 80+ for level 150 max servers. Level up your bary outside of the cave, you want stats like 4,000 health and 500% melee. Go to the cave and get the artifact. I recommend fighting everything because it is easy level ups, also go to both rooms as they both have explorer notes. The first one has the rex note near the water on the cliff, the behind the artifact there is the titanaboa explorer note. The other room has ruins there is the kaprosuchus dossier, and at the edge there is the leech dossier. The leech is in the deepest part of the room. Note bringing a bary with this power is basically cheesing the cave because it is super easy this way, I just recommend to bring a little bit of raw fish meat because centipedes known as arthopleura do a lot of damage. The rewards for this caves are the following: wooden shield, hide blueprints, hide armor, fishing rod, fishing rod blue print, metal pick and hatchet blue prints, or metal pick and metal hatchet, and 10x sooothing balm.

Can be relatively easy just make sure you have long range damage for the arthros because they take extra damage from projectiles, also be sure to look out for megalania they for they carry rabies and mega rabies I almost died because one looked just like it was a part if the cave ceiling, it wasn't it came down gave me mega rabies because I didn't use a tame for my thyla had died in the massive cave in lava but a death caption never came up so RIP thyla absolute alpha destroyer. But anyways a rifle makes this easier but a shotgun without a mount works great just make sure you bring extra armor because the arthros will belreak your armor really fast with their spit and you'll die very fast if you don't have more also don't get cornered. - Good Luck Survivors

Lots of insects btw

Bring an axe for the stuff

I forgot to add the cave is quite cold, so I recommend bring primitive hide armor because it is cheap, but durable and helpful with cold temperatures. There are loot crates on the path they give armor or armor and saddle blueprints, if you are low level I recommend grabbing them, there are also loot crates in the water, just be careful as baryonyxs are the best jumpers and swimmers but they can get stuck, apparently there is megaprihnas which do good damage and injure you. The water is also super cold so be careful. Keep surviving survivor.- Boss slayer guy.
