Mana Guardian: A floating armored sentinel, shaped like an animated stone construct with arcane energy trails instead of legs. It has engraved arcane symbols pulsing across its body, a large glowing eye, and rotating magical rings orbiting its core. Designed with carved stone textures accented by gold and blue, it features glowing runes, smooth metallic plating, cel-shaded details, and a semi-transparent magical shield effect for defense.
