Appearance: The longsword should have an elegant and sharp design, with intricate engravings along the blade and hilt, possibly depicting ancient runes or mythical symbols. The blade should gleam with a slight, magical aura, indicating its enchantment.
Properties: Emphasize the magic of the sword by adding a subtle glow or shimmer around the entire weapon.
Special Effects: Show the sword ignoring resistance to slashing damage by illustrating it cutting through a tough, armored surface with ease.
Bleeding Effect: Depict the bleeding effect by having a small scene where the sword has struck a creature. Show the wound glowing slightly with the same magical aura, and a trickle of spectral blood to indicate the ongoing bleeding damage. The creature should appear pained and marked by the deep wound.
