The bosun puts a whistle to its lips and produces a familiar piercing call to the crew. Any of the bosuns allies within 120 feet that can hear the whistle gain advantage on saving throws against being frightened or charmed until the bosun’s next turn. Additionally, any unconscious creatures within 120 feet that can hear the whistle are awoken, providing they could normally be awoken by an action.

The bosun has advantage on an attack roll against a creature if at least one of the bosun’s allies is within 5 ft. of the creature and the ally isn’t incapacitated.

The bosun has advantage on ability checks and saving throws to resist being knocked prone while aboard a ship.
