College of Thunder

Some Bards grow in talent, weaving beautiful ballads that
move their listeners to tears. Some bards just turn up the
volume. The college of thunder is a path for those that want
to be heard - to convey their message with great emphasis to
as many people as possible. They often are keenly interested
in innovating their instruments, finding new improvements
that allow them to make new, louder, sounds... the musicality
of those sounds is sometimes debated by more classical
artists. Lacking in subtlety, these bards are viewed as
innovators and pioneers by themselves... and
generally a large pain in the ears by most others,
most especially their proceeding generation.

Reverberating Echo

At 14th level, when expend a spell slot to cast a spell that
deals thunder or lightning damage on your turn, you can cast that spell
again on your next turn without expending a spell slot, but
any damage it deals is halved.
