Miasma

Whenever Miasma gets overly excited or nervous, she involuntarily lets out small bursts of flames from her mouth, akin to hiccupping. This often leads to humorous situations, especially when she's trying to keep a low profile.

Miasma has a peculiar reaction to certain potion ingredients, causing her to sneeze uncontrollably whenever she's around them. This can be both amusing and problematic during potion-making sessions, as her sneezes can sometimes accidentally mix ingredients or cause small explosions.

Unlike most dragons, Miasma's tail has a mind of its own. When she's happy or excited, her tail wags fervently, much like a dog's. This can be endearing but also occasionally hazardous, as her tail has been known to knock over delicate potion ingredients or break nearby objects.

Miasma has a penchant for singing while she works, but her singing voice is anything but melodic. Instead, it sounds like crackling flames and rumbling thunder, reflecting her fiery nature. Despite her lack of musical talent, she insists on serenading her potion-making process, much to the chagrin of her brothers.

Whenever Miasma becomes particularly focused or agitated, a noticeable heatwave radiates from her body, causing the surrounding air to shimmer. This can be uncomfortable for those around her, especially in confined spaces, but it's also handy for warming up chilly environments or quickly drying potion ingredients.
