Overview

Thieves Lair is a solo gold-farming dungeon designed for level 80-100 non-Divine characters. It is one of the most consistent sources of active gold generation, producing approximately 80-100 billion gold per run and up to 700 billion gold per account each week.

For efficient clears, a minimum of 900,000 Arts Attack is recommended. Arts Defense is the primary defensive stat due to the dungeon's combat mechanics.
