Buer is an enemy in Final Fantasy X encountered on the Thunder Plains. It has high Evasion and Magic Defense, and Wakka's attacks are the best to kill it. Another way is to have Lulu cast any of the Water spells. It uses a single Gaze attack that strikes one party member for magic damage and can occasionally cause Confusion.
In the original version, Buers drop weapons with Strength +3% and Magic +3% instead of Strength +5%, Magic +5%, and Distill Speed.
