One HP (hit point) is equivalent to one attack with the wooden sword. Where two different HP are listed, the first one refers to the weaker red version, the second one to the stronger blue version.
Sorting enemies by HP, you can see them in an order that is closely related to their overall strength. Moreover, the strongest enemies can be encountered only in areas that can be accessed later in the game.
|Armos||3||Inert suits of armor scattered around the Overworld that will come to life if Link touches them. They move at varying speeds, from extremely slow to extremely fast. They drop no treasure, but occasionally there is a secret passage or other item hidden beneath them that will be revealed when they begin to move.|
|Ghini||9||Ghost present in the cemetery. There is one Ghini to begin with in each area of the graveyard, and this is the "master" and the only one that is vulnerable to attack.

If Link touches a tombstone after the master is defeated, more Ghini will appear, and these will be invulnerable to attack.|

Where two HP (hit points) are listed, the first one refers to the weaker red version, the second one to the stronger blue version.
Sorting enemies by HP, you can see them in an order that is closely related to their overall strength.

The three strongest enemies are often referred to as "mini-bosses" or "sub-bosses".
