Spellcasting. The bard is a 4th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 12, +5 to hit with spell attacks). It has the following bard spells prepared:

Cantrips (at will): friends, mage hand, vicious mockery

1st level (4 slots): charm person, healing word, heroism, sleep, thunderwave

2nd level (3 slots): invisibility, shatter

3rd level (2 slots): call lightning

Song of Rest. The bard 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 bard can confer this benefit on itself as well.

Shred (2/Day). While holding the poweraxe with both hands, Yvelda can enter a state of extreme focus for up to one minute. While shredding, Yvelda must use both hands to play the poweraxe, her speed is halved and she may not climb, burrow, or swim. While shredding Yvelda has advantage on concentration checks and letting her replace all non-valued spell components with her playing. Yvelda may also give a d8 bardic inspiration to any creature within 60 feet that can hear her as a free action while shredding.

Poweraxe. Yvelda wields a specially enchanted greataxe with strings running down its shaft. The poweraxe may be welded as a magical greataxe or played as a magical instrument that may have its volume adjusted so it is heard from a distance of 5-200 feet.

Poweraxe. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) piercing damage.
