Lagoon Island Boss
The main boss of the Lagoon Islands is Iar Kaya, who is declared “the self-proclaimed mistress of the deep sea. But she is, in fact, a powerful witch who had her heartbroken by the captain of a sailing frigate.”
According to game history, Iar Kaya was promised by a sailor that he would love her and be with her, but instead, he used her to his advantage and captured her wand in a net with the help of his sailors. Luckily, she escaped the situation, but now she has trust issues and serious hatred for the visiting dwellers and vowed to throw them off the Island.
Fighting this triggered boss is not an easy task, so you must be prepared before facing her. This mission has a preparation time of about 3 minutes and will take about half an hour to get the job done as she is pretty sturdy. So, let’s talk about the proper strategies to beat her down.
How to Defeat Iar Kaya at Lagoon Island
As mentioned earlier, you must be at least at level 50 of combat and level 250 of equipped items before facing Iar Kara, as it will assist you in facing and fighting her effectively. The boss has enormous health, but with constant attacks and gradual damage, you can bring her health down slowly and steadily.
It is recommended to be close to her when she’s about to trigger her blue lazar attack as it spreads all over the nearby places and deals enormous damage. Also, make sure to dodge her red circular lazar attacks by maintaining a safe distance while she is initiating them. She will also spawn slugs from under the sea, which also deal damage if you come in contact with them.
The best strategy to beat Iar Kaya is to run around her in circles to dodge her serious attacks and counter-attacking while she is vulnerable. Maintain your patience, and don’t try to be over-aggressive. Keep damaging her and slowly bring her down.
When Iar Kara is finally defeated, there are pretty much chances that she will drop an island token, but it is not guaranteed. However, there are some rare rewards that a player will get after defeating this main boss of Lagoon Island.
Lagoon Island Loot And Rewards
Once you successfully complete all the questlines of Lagoon Island and defeat the final boss, you are guaranteed to get some special items as rewards. These include valuable items that increase your equipped items level and enhance your in-game abilities.
Players are most likely to get Wealth Runes after defeating Iar Kaya. Wealth Runes are one of the unique rune types in Lost Ark, as they give a special perk of enhancing the player’s Identity Gauge upon every successful hit.
The identity gauge is different for each class and depends on the rarity. Below are the different rune tiers that increase the player’s identity gauge depending upon their classes.
- Legendary: 40%
- Epic: 30%
- Rare: 20%
- Uncommon: 10%

The clams can provide ability stones, depending on the rarity. Other than claiming items and clams on the Lagoon Island, you can also look for Mokoko seeds on this land.
Lagoon Island Mokoko Seeds Location
