Mirumok Destroyer Offin Awakens

A new world/guild boss has awoken deep in the Mirumok Temple! Mirumok Destroyer Offin is an ancient weapon that absorbs energy from the spirits of the forest and delivers nothing but destruction to temple invaders. The Mirumok Destroyer Offin is piloted by the Watcher Offin Tett, an ancient construct made with pure Tett, a special element that only the Wizards of the Godr-Ayed can work with.

Where is Offin?

There are two ways to discover Mirumok Destroyer Offin.

Guild Boss: Mirumok Destroyer Offin/Watcher Offin Tett appears as a guild boss and can be picked up through the repeatable guild quest ‘[Boss Subjugation] Watcher of Mirumok Ruins’.
World Boss: Mirumok Destroyer Offin also appears as a World Boss and will be summoned at set times. You can find the Offin spawn times below.

[New World Boss Timetable]

Both Offins spawn in different locations, but they are both in the area of Mirumok Forest.

Taking Down Destroyer Offin

The ultimate goal in fighting the Mirumok Destroyer Offin is to take out the Watcher Offin Tett inside. During the fight, Watcher Offin Tett will be protected by a magic shield, so you will need to weaken that first before taking out the Watcher Offin Tett. There are 3 different ways to achieve this goal.

Method 1: Destroy 1 Root

For this method to work, you are going to need a lot of damage and coordination. First you get the Watcher Offin Tett to dismount the destroyer by destroying one root. Then you will need to switch to Matchlocks in order to destroy the shield before Watcher Offin Tett’s HP drops to 70%. If the shield is broken, Watcher Offin Tett will not get back inside the Destroyer, meaning you can then finish him off without worrying about the destroyer.

Method 2: Destroy 2 Roots

Similar to method 1, you will need to destroy the first root to make Watcher Offin Tett leave the destroyer. Then you will attack Watcher Offin Tett until his HP reaches 70%, at which point it will remount the destroyer. Then you will need to destroy another root to make the Watcher Offin Tett come out one more time. From there you attack it until Watcher Offin Tett reboards the destroyer at 30%. As 2 roots have been destroyed, the destroyer will be unable to draw enough energy to bring the shield back, so you can focus the destroyer to take out both Offin Tett and the Destroyer.

Method 3: Destroy 3 Roots.

This method is identical to method 2, but once Offin Tett reboards the destroyer at 30%, you focus down the last remaining root to make Offin Tett unmount the destroyer one more time. You will be able to take him out relatively quickly from there.

With Mirumok Destroyer Offin, there are 3 ways to obtain rewards.

The first is similar to other world bosses where you can just pick up items after ‘Watcher Offin Tett’ has been defeated. Rewards here are generally distributed based on the amount of damage dealt, but anyone who deals damage will be able to get something from the fight.

The second method is to be one of the top 30 adventurers that help to destroy the root of Mirumok Destroyer Offin. These 30 adventurers will find extra rewards when they come to loot the monster.

The third method is to be one of the top 30 Adventurers that help to destroy the Destroyer Offin’s shield. This method is trickier to be a part of since destroying the shield requires a matchlock, but getting rewards from this world boss is incredibly worthwhile.

The rarest item you can get from defeating Mirumok Destroyer Offin is the ‘Offin Tett’s Light Sealed Weapon’. You can get this by receiving and opening Offin Tett’s Light Sealed weapon box. This weapon has lower accuracy than a Kzarka weapon, but has higher AP. It also has an additional +2 Critical hit compared to Kzarka weapons +1 Attack/Casting Speed bonus.

In order to talk to her, you must have at least 7 entrances in the ‘Kamasylvia Entrance Adventure Journal I’.
