Heavy Sentry

Heavy Sentries are enemies in Hollow Knight. Reanimated by the Infection, these walking corpses wield a greatnail, guarding the City of Tears even in death.

Behaviour and Tactics
They have three attacks: The best moment to hit them is when they charge. Simply jump over them and execute a downward strike or use Vengeful Spirit or Shade Soul when they charge, as they will have no way to avoid it. They can also be hit just after their normal swing attack.
 * Overhead Swing: they unleash a powerful swing in an arc in front of them.
 * Charge: they charge at the Knight with their Nail held in front of them.
 * Hop: when the Knight attempts jumping over them, they react by hopping in the air, dealing contact damage. As they land on the ground, they will perform an Overhead Swing.

Location
They are only found within the City of Tears, in small numbers.
