Personality

She communicates through a rapid-fire remix of sounds: a harp strum for 'thank you,' a falling boulder for 'no,' and the sound of a cheering crowd when she introduces herself. She is physically incapable of standing still, constantly twitching her talons in a rhythmic beat against her golden-scaled throat.

Ideal

Spectacle. 'If the world is a stage, I shall be the sun that illuminates it.'

Bond

The 'Great Golden Echo'—the voice of the dragon blood inside her that she believes is a living god guiding her to the sky.

Flaw

She has zero concept of stealth or consequences; if a situation calls for a whisper, she provides a sonic boom.

Backstory

In the damp, silent gutters of the city, Kack-Boom was born into the gray mimicry of her kind. While other Kenku were content to echo the clink of stolen coins, Kack-Boom was obsessed with the sounds of the sky: the crack of thunder, the whistle of a descending hawk, and the roar of the forge. Her life shattered and reformed during a bungled heist in a hidden laboratory where she accidentally imbibed 'Aurum Sanguinis'—the concentrated, volatile blood of a dormant Gold Dragon. The liquid didn't kill her; it ignited. It filled the hollow silence of her soul with a resonant, metallic hum that drowned out the world, manifesting as a brilliant, golden fire that smells of ozone and toasted cinnamon.

Now, Kack-Boom believes herself the chosen avatar of 'The Great Golden Echo,' a divine resonance that demands to be heard. She views her inability to speak original words not as a curse, but as a musical challenge. To cast a spell, she must first 'record' the world—layering the sound of a shattering stained-glass window with the hiss of a boiling kettle to produce a scorching beam of light. She travels from city to city, seeking the grandest stages and the tallest towers, determined to perform a 'final' spell so loud and so bright that it will finally break the Kenku curse and lift her entire race back into the clouds.

Abilities & Actions

Layered Resonance (Passive)

Kack-Boom’s magic is powered by the sounds she mimics. When she casts a spell that deals damage, she can choose to change the damage type to Thunder by layering the sounds of breaking stone and crashing waves into the verbal component.

Aurum Spark (Bonus Action)

Kack-Boom taps into her golden blood to manifest spectral, shimmering wings. She gains a flying speed of 30 feet until the end of her turn. If she ends her turn in the air, she falls unless she has another way to stay aloft.

The Golden Fire-Flower (3/Day)

Kack-Boom uses her signature item, a conjured blossom of liquid sun. She hurls the flower at a point within 60 feet. It explodes with the sound of a thousand glass bells. Each creature in a 10-foot radius must make a DC 15 Dexterity saving throw, taking 4d6 fire damage and 4d6 radiant damage on a failed save, or half as much on a success.

Echoing Cackle (Reaction)

When a creature Kack-Boom can see within 30 feet misses her with an attack, she mimics the sound of their weapon breaking. The attacker must succeed on a DC 15 Wisdom saving throw or be deafened until the end of its next turn.

DM Notes

Kack-Boom doesn't talk; she 'broadcasts.' Use a soundboard app or vivid descriptions of noises to represent her speech. She gestures wildly with her wings (if manifested) or her feathered arms. She reacts to boredom by creating small, harmless sparks of golden fire that dance like butterflies. She will never voluntarily enter a basement or a cave; she needs to see the sky.
