Formidable Foe Challenge
Last updated 2025-07-31
A Formidable Foe Challenge is a non-respawnable encounter found in most areas of the open world.
The challenge either consists of an Elite enemy with supporting Normal enemies in a single wave, or only normal enemies split into several battles. These enemies have a higher level compared to other enemies in the area.
When the challenge is cleared, the player may claim the treasure chest they were guarding, which is either a Bountiful or Precious chest. Chests guarded solely by normal enemies grant a Bountiful Chest, while those guarded by Elite enemies grant a Precious chest.
Formidable Foe Challenges can be identified by their unique 
icon on the map, which will disappear once the corresponding treasure tied to the challenge is claimed. Multiple Formidable Foe Challenges can appear in a single area.
Gameplay Notes
- If a Formidable Foe Challenge has multiple enemies in the overworld, the player does not have to defeat both enemies in sequence so long as the player breaks them apart from one another.
