Tek Cave

The Tek Cave is a cave located at the summit of the volcano, and upon completing said cave, the player will teleport to the Hall of History, which leads you to the game's final boss.

Note that the Cave entrance only opens for 5 minutes, so bring in your tames in time. After that, you have 60 minutes to complete the cave and start the boss fight. This includes that you must have passed the entire Hall of History. Everything that stays in the Hall of History after the timer has expired dies. If you try to teleport into the Hall of History via cheat commands, you die if the boss fight has already started (or is still in progress).

Tribute Requirements
The following items are needed to open the Tek Cave entrance. These items are not consumed in the process:

It is worth noting that the greater difficulty trophies can be used to open the Tek Cave entrance at lower difficulties (i.e. the, and  trophies can open the Tek Cave at Gamma difficulty).

Tribute Spawn Commands
Uses these commands to give yourself all the items needed for tribute:

Recommended Equipment

 * This is the hottest and the coldest place you can find on The Island. is crucial to deal with the unbelievable heat in Tek Cave. Then the temperature will turn upside-down after you pass the border dividing the cave from the terminal, requiring player to change to . It's highly-advised to use charged  to deal with both extreme environments.
 * You will want to bring some and  along with reserves of water and food, as well as : If you are burning or freezing, your natural health regeneration is suspended.
 * You will need a lot of powerful weapons. It is best to use ascendant quality gear, such as a, , or any other weaponry.
 * Bring any kind of ranged weapons (even a Primitive is fine) to aggro lots of wild animals in the cave and make them fall in the lava pits. It makes the cave much easier, especially if you can send the Giga in the lava. Gigas, however, do not spawn on Gamma difficulty. There will still be a Giga guarding the entrance to the terminal area.
 * Bringing sacrificial tames such as Carbonemys is a good idea to send them into the lava once you have shot it with a using a, drawing wild Dinos with it.
 * will work fine if you get Mega Rabies from Megalania.
 * It is completely possible to do the entire cave in around 35 mins with a set of and using some, Where you just crawl through the cave and get zero aggro and no chance of losing tames; however, you cannot ascend unless the final boss is beaten (introduced in patch 267.0).

Dangers

 * Lava pits. Your unridden animals can easily fall into the lava from the narrow bridges, especially when they are on neutral and fighting the wild dinos. Because of this, it is recommended to bring more players rather than bringing in unridden dinos.
 * Getting knocked off your mount.
 * Massive swarms of high level dinos.
 * The Giganotosaurus guarding the entrance to the portal.
 * Extreme heat and chill: 60℃ in Tek Cave, -28℃ at the terminal, Hall of History, and Overseer Arena. It will burn/freeze players if they do not have corresponding gears equipped.
 * The lava in the caldera in front of the gate (before entering the cave) hurts a lot, so make sure your Rexes don't step into it. Make sure you bring enough raw meat in case one of your Rexes misstep to be able to forcefeed them to max health if lava burned them.
 * Lava does 200 damage if you or your Creatures step into it
 * Both riders & following dinos can be stuck in the cave's geometry. For this reason, ensure that there is adequate distance between players & that each player carries a small subset of unridden dinos behind them, similar to a conga line.

Strategy

 * It is highly advised to make all Dinos follow each other, similar to a conga line or the way ants follow each other and make their follow distance low as they might tighten the knot and fall. More players mean shorter chains of your tames if you like to.
 * Use an extra group to clear the way for the overseer fighters.
 * Bring an Otter since it provides insulation which is perfect for the temperature difference.
 * A Yutyrannus can scare the Purlovias out of their burrows.
 * a Daeodon to heal your tames is suggested.
 * Megalosaurs are suggested as they are stronger than Rexes and Therizinos but have a sleep timer.
 * The Tek Helmet can show burrowed purlovias - even though they don‘t attack players on big mounts like Rexes or a Yutyrannus until attacked, changing your mount during their presence turns fatal quickly. Their jump can stun when dismounted.

If you have access to the Genesis DLC, the high quality saddles that can be gained from missions will prove useful for getting through this cave.

Creatures
All creatures found in Tek Cave spawn above level 300 (with the exception of Giganotosaurus, which spawns at level 600, but can't be tamed), rendering them impossible to tame.

Restrictions
Due to the opening size of the Tek Cave entrance upon opening, only certain size of the dino or creatures can fit into the cave.

Once the cave is sealed, no creature will be able to leave the cave until the in its arena is defeated. Any creature still alive in the arena will be transported to the entrance of the Tek Cave.

The following creatures are too big to fit into the cave entrance and will not be able to enter by any means:

The following creatures cannot be warped into Overseer boss fight, but can enter the Tek Cave:
