The Elixir of Fury is a small, intricately designed vial with a robust, angular shape, featuring a tightly sealed stopper to prevent spills. The glass is thick and slightly tinted red, giving the contained liquid a menacing glow. The vial is adorned with golden runes that pulse faintly, suggesting the potent, rage-inducing properties of the elixir within. The liquid itself is a vibrant, swirling crimson, with occasional sparks of orange and yellow, mimicking the appearance of a contained flame.
