Type(s) Passive (Type B) Game(s) Heroes

Obstruct (Japanese: 進軍阻止 March Obstruction) is a three-tiered passive type B skill which debuted in Fire Emblem Heroes; the individual tiers of the skill are known as Obstruct 1, Obstruct 2, and Obstruct 3 in order from lowest to highest. Units with a Obstruct skill will prevent any enemy that does not have a Pass skill from traversing spaces adjacent to the user, provided their HP is at or above a certain threshold; the percentage of total HP required to activate the skill decreases with the skill's tier.
