Starsnake

Starsnakes  were beautiful, solitary creatures, that repelled magic as they slept and delighting in playing pranks on intelligent creatures. They were sometimes tamed as familiars.

Appearance
The star snake had a coat of glossy, shimmering scales of blue, green and red with iridescent, silk-like wings that resembled those of a butterfly. Even though they averaged about 8 to 10 feet in length, they typically weighed under 10 lbs.

Diet
Despite having such exotic features and remarkable qualities, starsnakes fed on simple rodents.

Personality
These magical creatures were hermaphroditic, which served them well as they were completely anti-social and found their own kind repellent. They would typically only be active at twilight, coming to rest in an area that was well traveled by intelligent life. They were pranksters, planting ridiculous yet harmless suggestions to passerby. This behavior gave way to the phrase "charmed by a starsnake".

Powers
When starsnakes slept, they created a dreamshield around themselves, an aura that would absorb spells and magical from abilities. This energy was converted to electricity, and any creature foolish enough to touch a sleeping starsnake would receive a static discharge.
