防御 is an enemy-exclusive buff in 异度神剑X. 防御 makes the 敌人 unable to move and attack, but reduces the amount of damage taken from attacks and makes it immune to mobility-impairing debuffs. However, while appendages take reduced damage, their health meter is reduced at the same rate as normal, making it easier to destroy appendages without killing the 敌人.
防御 is usually gained by using a Battle Art named 防守. An 敌人 in a 防御 state hunkers down and protects its face using its arms if it has any.
