Armor provides crucial defense against enemy attacks. Shields offer a chance to block physical attacks and sometimes magic. Helmets and Hats increase physical and magical defense respectively. Armor (heavy) provides high physical defense, while Robes (light) offer better magical defense and sometimes elemental resistances.
Choosing the right armor depends on your unit's role. Front-line physical attackers benefit from heavy armor and shields, while magic users prefer robes and hats. Look for armor that provides elemental resistances or immunities, as these can be game-changers in certain battles. upgrade your armor regularly at shops.
