Wind based equipment is mainly found in Legaia 2: Duel Saga. Legend of Legaia's only Wind based accessory is the Tempest Jewel. In Duel Saga, Wind equipment ranges from weapons that add the Wind element to attacks, to armor that reduces damage against Wind, to collectibles that have to do with the element itself.
There are Arts in both Legend of Legaia and Legaia 2: Duel Saga that utilize the element of Wind. All of Noa's physical attacks hit with the Wind element considered. In Legaia 2: Duel Saga, Maya can use the Wind magic spells Windblade and Toxic Cloud.
In Legend of Legaia, Wind summon spells are used particularly effectively by Noa. Swordie is the earliest Wind Seru that can be obtained and summoned, followed by Nova and Barra. The most powerful summon spell is Terra's Queen Twister. The magic effect of Wind element summons is a reduction of the targeted enemy's SPD stat.
Legaia 2: Duel Saga utilizes no Wind element summons.
Multiple enemies in Legend of Legaia and Legaia 2: Duel Saga use Wind based attacks. One of the most iconic enemy Wind attacks in Legend of Legaia is Rogue Wind.
