Tiat Instance (Lv. 82+)

In the Gracia Final update, the Seed of Destruction and its main boss instance, Tiat, were introduced into the game.

On L2Avalon, Tiat is one of the largest high-level instances, designed for organized groups of advanced players. The encounter features mechanics inspired by castle and fortress sieges, creating a large-scale assault experience rather than a traditional boss fight.

This instance is a key part of late-game progression and offers valuable rewards such as:

• Icarus weapons

• Forgotten Scrolls

• Other high-level progression items

Simplified L2Avalon Version

On L2Avalon, the original version of the instance has been simplified to focus on the core boss encounter.

In the retail version, players were required to progress through additional rooms and destroy three crystals before facing the final boss. On this server:

• Access to the crystal rooms is closed

• The crystal-destruction phase is removed

• Players can proceed directly to the fight against Tiat

This adjustment makes the instance more accessible while keeping the focus on the main battle.

Main Boss

The final boss of the instance is:

• Tiat — Witch of the Dragon of Darkness (Lv. 82)

Tiat is the central objective of the instance and provides both valuable loot and Soul Crystal (SA) leveling opportunities.

Soul Crystal Leveling

Tiat allows players to upgrade their weapon SA from level 10 up to level 16.

• Upgrade chance is individual for each party member who lands the final hit

• Calculations are separate for each eligible player

Possible rewards include:

• Icarus weapons

• Forgotten Scrolls

• Other valuable boss drops depending on configuration

Summary

Tiat Instance is a large-scale, high-level encounter for level 82+ players, designed for organized groups and focused on late-game progression.

With simplified access, strong rewards, and high Soul Crystal upgrade potential, it serves as one of the most important instances for advanced players on L2Avalon.
