The Stingray is an enemy in Final Fantasy V, a rare encounter that can be found in the sea southeast of the Phoenix Tower and the small lake near Carwen. The area for this encounter is extremely specific: the player must skirt the coast above the sunken Walse Tower. In the GBA version, it can also appear in the River of Souls, in the Sealed Temple.
A particularly easy way to find this enemy in the lake area in the North American and Japanese GBA versions is to Quicksave on the land next to their encounter area, continue, get in the boat, move around a bit, and the second enemy met should be the Stingray.
The best method to quickly take down a Stingray is to bring a party entirely outfitted with Blue Magic and Level 3 Flare. It is also a good strategy to have a party member that knows the Mystic Knight's Spellblade ability, and the Ranger's Rapid Fire ability. The player should enchant their blade with Flare, and then use Rapid Fire repeatedly. This tactic works well with most enchantable blades.
