if (origin !== target && origin.isAlive()) {
  // Determine the damage dealt.
  var damage = target.hp / 8;
  // Round up the damage.
  damage = Math.ceil(damage);
  // Play the healing animation on the original caster.
  origin.startAnimation(46);
  // Original caster gains HP.
  origin.gainHp(damage);
  // Show the HP gained.
  origin.startDamagePopup();
  // Clears the original caster's HP popup.
  origin.clearResult();
  // Play the poison animation on the target.
  target.startAnimation(59);
  // Damage the target's HP.
  target.gainHp(-damage);
  // Check if the target is dead.
