Magical Potion Bottle

Description

A mystical glass potion bottle with a teardrop shape and a cork stopper. The bottle is filled with a swirling, glowing liquid in shades of purple and blue. Etch ancient runes lightly onto the glass surface, and make the bottle appear slightly frosted. The cork stopper should have a small metallic emblem with a magical sigil embedded into it. Add a faint, ethereal mist escaping from the cork.
