The Fell Arms are a set of powerful weapons that grow stronger as you defeat enemies. Collecting all of them is a lengthy but rewarding side quest that culminates in a challenging post-game boss. The quest begins much later in the game, typically after a certain story event involving Duke. Each Fell Arm is hidden in a specific location, often guarded by a powerful monster or requiring a specific trigger. For example, the Abyssion (Yuri's Fell Arm) is found in the Erealumen Crystallands. Keep an eye out for glowing red objects in dungeons or specific dialogue triggers in towns. Once all are collected, you'll unlock the final challenge. This quest is a significant time investment but offers some of the best weapons in the game.
