HWYLA entity health rounding error

[ShinyArmorYT]

After dealing a critical hit to an enemy with an empty hand, the enemy's health displays as if it lost just half a heart. After that, when dealing non-critical hits, the enemy's health alternates between taking 2 damage and taking 0 damage, which is incorrect.
