Island of Terror Dungeon Guide - Throne & Liberty

Welcome to our Island of Terror dungeon guide for Throne & Liberty. 

In this guide, we will explain the mechanics of all bosses and notable mobs in the Island of Terror, and the strategy for beating them and clearing the dungeon. 

Island of Terror is a more difficult version of Tyrant’s Isle – the boss mechanics are similar but have been made more complicated and challenging.

For more guides about a variety of topics in TL, please check our Throne & Liberty Guides Database.

This boss is very similar to the Shaman Executioner in Tyrant's Isle, with mostly the same mechanics. However, this boss will spawn two waves instead of one, during the Burning Water mechanic. 

The mechanics of the Frenzied Reptilian Executioner are:

This boss is a harder version of the Reptilian Gladiator in Tyrant's Isle. His mechanics are similar, but tuned to be more difficult. 

During the fight, a player in the party will glow red. This player is about to be charged by the boss – anyone hit by the charge will take heavy damage. The red player should hide behind one of the torches (and other players should get out of the way, too). The boss will crash into the torch and be stunned.

In the Island of Terror version of the boss fight, the Gladiator will charge twice in a row instead of just once. The torch totems will now break when the boss hits them. 

Kertaki is currently one of the most challenging dungeon bosses in Throne & Liberty. To finish smoothly, it requires an experienced group with knowledge of the mechanics and good coordination.

Below are the mechanics of the Kertaki boss in Island of Terror.

Kertaki will launch four fireballs at the tank, then stun the tank. The stun will be followed up with a heavy attack that deals around 15,000 damage if it is not mitigated. An ally should cast a cleanse skill (such as Purifying Touch) on the tank to break them out of the stun, allowing them to block the heavy attack. If the tank is left to fend for themselves, they will have a hard time staying alive when this happens.

The boss appears to “pulsate” with a purple colour around his body, then shortly after does a spinning attack that deals heavy damage to everyone. To counteract this, you must block the attack, significantly reducing the damage.

A purple square indicator will appear on the boss, showing that it is charging up the Fury Attack. You need to perform a moving block (use your block skill while moving) to properly block this attack, and make sure to follow up with your counter-attack immediately afterwards. Otherwise, the next time you try to block, you will instead launch your counter-attack, a mistake which is likely to get you killed.

Soon after the Fury Attack, the boss will launch three fireballs at random players. Everyone must stand on or next to the small vents on the ground – make sure the fireball lands on the vent, but try to move out of the way before it lands so you avoid the damage. The fireballs need to land on the vents to clear the fog that has spawned all around the room. All the vents need to be clear of fog, otherwise the geyser mechanic will be impossible (more on that below).

If you make a mistake and the fireball misses the vent, it’s still possible to salvage the situation. The fireballs leave some blue fire on the ground – run into the fire to pick up a burning debuff, then quickly run to the vent before the burning debuff expires. This should be sufficient to clear a small amount of fog from around the vent, but you will take some damage when carrying the burning debuff.

After the fireballs, several Baby Lizards will spawn. These are extra mobs that will run around attacking players. To deal with them quickly, it's recommended that the team bunches up around the boss (the baby lizards will follow) and then use AOE attacks to eliminate them all.

After spawning the Baby Lizards, the boss will do two heavy attacks, both of which should be avoided with a moving block. If the heavy attacks hit you, they will put a heavy Movement Speed debuff on you which makes the next part much harder.

Tip: A player with Longbow can use Nature’s Blessing to cleanse the Movement Speed debuff from players at the start of the Geysir phase!

After the second heavy attack, the geyser phase will begin. In the Fireball phase, you should have cleared the fog around the geysers, so you can now use them. The boss will charge up a massive ground slam that sends out a purple shockwave, instantly killing any player on the ground. The only way to avoid this is to enter the bubbling geyser – it will then fire you into the air, allowing you to avoid the shockwave. Only one of the vents will have an active geyser, and everyone needs to quickly find and run to it – this is why it was important to clear every vent in the fireball phase, because if you miss one of them and that one turns out to be the correct geyser, then you are certain to wipe at this point.

Below 50% HP: The boss will do the Geyser attack twice in a row. After surviving the first one, you quickly need to find the second bubbling geyser.

This is the final mechanic of the Kertaki boss fight in Island of Terror, and the most complicated one.

The boss pulls all players close to him and then transforms everyone into a rat. The goal here is to avoid attacks and cleanse the rat curse from yourself, but you have to be very careful along the way to avoid dying.

The best way to go about this is as follows:

As mentioned above, it is imperative that everyone remain patient and play the “rat game” as intended. If you try to run to the blue plants and cleanse immediately or hide in the ground for the entire phase, you will just cause a wipe. Spread out evenly, stay calm, and watch what the boss is doing!

Below 50% HP: The boss will become invisible during the Rat phase, making it even harder. However, if you look carefully you can still see what the boss is doing because his shadow is still visible – look which way his shadow is pointing to determine if it is your turn to dig.

After the Rat Transformation phase, the boss will cycle through the mechanics again, with the only difference being the harder versions of Geysers and Rat Transformation become active if the boss has less than 50% HP remaining. The mechanics can be quite intimidating if you’re new to this fight, but try to stay calm and focus on staying alive – dealing DPS during complicated mechanics is something to worry about once you’re comfortable.

This is, without a doubt, one of the hardest boss fights in the game at the moment, so congratulations if you managed to finish it!
