Effect

If performed correctly, on the player’s screen only, the Energy Sword’s basic image will be replaced by a ghostly, active aura. In Halo 3, when attacking any target that doesn't turn the reticule red, the sword will materialize, but the swiping animation of the sword on the player’s screen will be canceled. When the player attacks allies with this trick, they "mysteriously drop dead".

Usually, a faint shimmer can be seen with the sword. The glitch causes the Sword to vanish, but leaves the shimmer untouched.
