Trials of Chult
Better perform checks
1/day can add + 5 to Perform checks for Bardic Songs. Last until bard is done singing or rolls a 1. Also being Polked will stop gong from working for rest of the day. Percussion
This is even more powerful when you consider you can basically add double your skill ranks. You have your normal ranks in Perform. Then you can have ranks in Perform (percussion) and have a + 5 on top of that. So a 5th level bard caps at 8 ranks in a skill could have 8 in perform, 8 in percussion and a plus 5 for the gong would be rolling +21 during the gong battle!
