Battle Hymn

You play a ballad narrating the actions of your allies in battle.

When an ally in range of your voice would make an attack roll, damage roll, or savings throw, you may use your reaction to roll a [roll]1d6[/roll]and add the result to their roll.

This die becomes a [roll]1d8[/roll] at 5th level, a [roll]1d10[/roll] at 10th level, and a [roll]1d12[/roll] at 15th level.
