Horde. The crew can occupy another creature’s space and vice versa, and the horde can move through any opening large enough for a Medium skeleton. Additionally, the crew is immune to any spell or effect that would alter its form.   Horde Turn Resistance. The crew has advantage on saving throws against any effect that turns undead. Additionally, the crew can be affected by the Destroy Undead feature regardless of CR limits, but has advantage on the saving throw against it and is not destroyed on a failed save. Instead, it takes radiant damage equal to 10 × the cleric’s level on a failed save, or half as much damage on a success.   Reactive. The crew can take one reaction on every turn in combat.
