A page containing information about the Monster Arena Sidequest in the game Final Fantasy X (FFX, FF10). Read on to know more about the sidequest's rewards and unlockable bosses.

Monster Arena Objective

Capturing Fiends

To unlock monsters in the arena, you must first capture fiends all throughout Spira. A capture weapon is required and the killing blow to the enemies must be dealt with by the user equipping the capture weapon. Enemies can be captured by damaging abilities such as quick hit, dark strike, and mug. They cannot however, be defeated by magic.

Unlockable Fiends

3 types of Fiends can be unlocked in the Monster Arena. Each fiend in each category can make Braska's Final Aeon look like a joke and proper preparation and leveling are required to best these enemies.

Monster Hunting Tips

2nd Slot

Attaching a Deathstrike ability to an equipment with the capture ability.

The capture weapons provided in the arena comes with a second empty slot. Adding status ailments such as death strike or Stone touch can be effective and will still count as a capture. Adding utility abilities such as counter attack and first strike can also be helpful against the stronger fiends.

Hard to Find Monsters
