Year 5 takes you to the intricate Veo Lu Sluice, a water-management facility filled with aquatic enemies and environmental puzzles. You'll encounter more Sahagins and the powerful Ahriman. The dungeon requires you to manipulate water levels to open new paths. The boss of Veo Lu Sluice is the Giant Crab, a heavily armored crustacean. It's resistant to physical attacks. Use Thunder magic and attack its exposed underside.
Next, you'll brave the vast and treacherous Lynari Desert. This open-world-like area is home to Sand Worms, Antlions, and the elusive Cactuar. The desert features sandstorms that can disorient you and quicksand pits. The boss of Lynari Desert is the Sand Worm, a colossal version of the regular enemies. It burrows and surfaces, similar to the Mine Worm. Blizzard magic is effective. Collect the Myrrh drop and prepare for the final confrontation.
