Bards of the College of Shanties have an infectious voice that begs their friends to join in on their performances. These bards often start a shanty that quickly spreads throughout their whole crew, boosting morale and combat prowess alike. Even in the toughest of times, a College of Shanties bard can start a tune that's irresistibly awe inspiring and motivating. Through this music, they create an unrivaled kinship with all those who chose to join them in song.

Maritime Ballad

Once per long rest, you can use a bonus action to expend a use of your bardic inspiration to start a Shanty. If you do so, you can use your bonus action on subsequent turns to continue the Shanty. If you do not use your bonus action to continue the Shanty on subsequent turns, it ends early. 

Creatures who you allow to join the Shanty can use their reaction on your turn to gain the effects of the Shanty that round. They can use their reaction on any round, and gain only that round’s effect when it is used.

The Shanty lasts for three battle rounds, and you gain an additional battle round effect at Bard levels 5, 10, and 15.
