Epic fantasy battle scene in a photorealistic, vibrant yet slightly desaturated forest. A paladin stands in shining, intricate armor, wielding a subtly radiant sword and shield. Beside him is a mysterious wizard in a hooded robe, the fabric adorned with intricate arcane symbols, clutching a staff with a softly glowing orb. The wizard's face is shadowed by the hood, adding an air of mystique. A skilled ranger stands on the other side, clad in a finely detailed leather cloak, with a longbow drawn. The trio faces a towering, three-headed dragon, its richly textured scales showcasing muted tones. The forest is illuminated with sharp, clear lighting, emphasizing the crisp details of the characters and the vast creature. Enliven the scene with creative elements: sparkling magical energy around the wizard, the paladin's sword with an ornate design, the dragon's eyes glowing with an intense light, and a gentle mist hovering near the forest floor, adding an ethereal allure.
