Access and Modification

These fields are combined to save space in an expected 16-bit struct alignment.

Use mobile_incr_hp() to modify.

Death Handling

Death occurs when the HP half reaches 0.

This value should be set to MOBILE_HP_DEATH on this mobile's death blow. From there, the engine will increment it up to its final value, -1, where the mobile will be deleted.

This allows for a relatively simple "blinking" death animation to occur by hiding frames for mobiles on negative even HP values.
