Spectral Razor

Creates the effect of an invisible blade which can be used to cut and slash victims. This immaterial weapon can be used at a range in yards equal to the caster’s POW x3. Damage is 1D6 per round. The spell takes 2 rounds to cast and costs 2 sanity points and 2 magic points. For each additional round of effect, the caster must pay another 2 magic points.
A spectral Razor target must be visible. If concealed or half hidden behind obstacles or obstructions, the damage is done to intervening objects until the keeper believes enough damage has been done that the target is visible and vulnerable.
