The Tincture of Queensfoil is a small, ornate vial containing a luminous, purple-hued liquid that seems to swirl with an inner light. The vial is crafted from delicate glass with intricate silver filigree wrapping around its body, featuring floral motifs that resemble the Queensfoil plant. The stopper is made of polished silver, topped with a small, glowing gem that pulses faintly in sync with the liquid inside. The overall design is elegant and mystical, suggesting its powerful and rare nature.
