Beginning at 2nd level, you can use soothing music or oration to help revitalize your wounded allies during a short rest. If you or any friendly creatures who can hear your performance regain hit points at the end of the short rest, each of those creatures regains an extra 1d6 hit points. The extra hit points increase when you reach certain levels in this class: to 1d8 at 9th level, to 1d 10 at 13th level, and to 1d 12 at 17th level.
Starting at 2nd level, you can add half your proficiency bonus, rounded down, to any ability check you make that doesn’t already include your proficiency bonus.
