Word of ghostly shadows

Primary action. Does not provoke. You utter a single word of ending. All those within 60' are obliterated. Instant. All within range can make an AGL check to drop prone which might check them. Being prone counts as slight cover to this spell. Those with cover may survive- make LIF, AGL, SDF and CON checks. For those with slight cover can fail only one check, those with good cover can fail two, excellent cover can fail three and only take damage rather than be obliterated. You may also sacrifice your shield for another level of cover. If you are in total cover, you are protected from this. For each check that you succeed in you only take 2d6 energy damage. If you fail a check you take 4d6 energy damage (assuming you are not obliterated). Only a ghostly shadow of those destroyed remain. Survivors must also make MAG check or be blinded (permanent). Caster is useless for until the end of his next round after casting this spell.
