Lost Island's boss, fought at the Ancient Proving Grounds. A giant Dinopithecus that fights from the cliffs as much as from the floor.
Its tribute is the widest of any boss: each difficulty asks for its own four artifacts — only the Hunter repeats — so a full clear of the map's caves is the real cost.
After being teleported into the boss arena located at Ancient Proving Grounds, head down the path, beach on your left, cliff face on your right. You'll quickly come to a short tunnel on your right which leads through the cliff face and into a circular clearing where the boss fight takes place.
The boss is down the far end. Make sure you bring your whole group inside before starting the fight. Once the fight starts, the path leading in will be sealed with a force field. Some tames may get teleported in, others will not (if left outside).
Once the battle with the Dinopithecus King starts, he will jump down from his cliff to attack and call swarms of 
Dinopithecus to aid him - some of which either riding 
Amargasaurus or lifted in the air by 
Sinomacrops. On occasion, the boss will leap up to the top of the surrounding cliffs to barrage the players and tames with Infested 
Grenades. Eventually, he will jump back to the ground with a slamming attack. Similarly to the 
Dragon, the Dinopithecus King also has a bite attack that will slowly drain 20% of any dino's health hit by it.
The Dinopithecus that will rush in to protect their king can easily overwhelm your group and can also throw feces at your tames, inflicting a 10 second slow debuff. Dinopithecus that are being carried in the air by Sinomacrops will pelt you with rocks and grenades that can damage riders directly. Amargasaurus carrying Dinopithecus can utilize their spikes to lay traps on the field which can either reduce armor quality, burn, or freeze your dinos.
The Dinopithecus King himself will utilize the Amargasaurus spikes on his arms to inflict similar debuffs to your dinos as described above, as well as inflict a 20% health drain with his bite attack. His slamming attack can also dismount you from your tame, potentially making for an easy kill if he hits you with one of his following melee attacks.
Every enemy creature during the boss fight gets reduced damage taken.
Luring the Dinopithecus King into one of the caves near the entrance of the arena can be very beneficial as it will block him from jumping to the top of the cliffs around the middle of the arena.
The large Infested Grenades the Dinopithecus King will throw do great damage, but can be destroyed similarly to the floating orbs in the 
Rockwell fight with a ranged weapon like a 
Fabricated Sniper Rifle.
Artifact of the Hunter carries over between tiers; the other three change every difficulty, so plan the cave runs around the tier you actually want.
