Requirements The zombie horse's previous action was a jaws Strike that dealt damage to its target

Effect the zombie horse makes a second jaws Strike as it violently gnashes its teeth and bites deep into the target's flesh. On a success, the target takes an additional 1d4 persistent bleed damage.

Feast (manipulate)

If the zombie horse is adjacent to a helpless or Unconscious creature, or a deceased creature that died in the past hour, the zombie can feast upon its flesh to heal itself. This restores 1 healing Hit Point. If the creature is alive, the zombie horse deals damage equal to its jaws damage.
