Bardic Spirit

Amorphous. The bardic spirit can move through a space as narrow as 1 inch wide without squeezing.

Shadow Stealth. While in dim light or darkness, the bardic spirit can take the Hide action as a bonus action.

Song of Rest. The bardic spirit can perform a song while taking a short rest. Any ally who hears the song regains an extra 1d6 hit points if it spends any Hit Dice to regain hit points at the end of that rest. The bardic spirit can confer this benefit on itself as well.

Spellcasting. The bardic spirit is a 4th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 12, +4 to hit with spell attacks). It has the following bard spells prepared:

Cantrips (at will): mending, minor illusion, prestidigitation

1st level (4 slots): comprehend languages, healing word, heroism, sleep

2nd level (3 slots): invisibility, calm emotions

Taunt (2/Day). The bardic spirit can use a bonus action on its turn to target one creature within 30 feet of it. If the target can hear the bardic spirit, the target must succeed on a DC 12 Charisma saving throw or have disadvantage on ability checks, attack rolls, and saving throws until the start of the bardic spirit's next turn.
