In Vas Grav Corp

In Vas Grav Corp is the attack spell at the time of Ultima V.

Spell Description
Casting the spell creates a "cone of energy", a fan-shaped area in front of the mage where everything is wiped out instantly. Only truly enourmously strong foes can survive this spell of death. However, it is very seldomly used. The reasons for this are twofold:
 * For one, the spell has very high requirements and when the mage finally reaches these, they usually already have the means to deal with the foes in a more regular way.
 * Second and worst, the spell won't discriminate between friend or foe, and companions who accidentaly get in the way are destroyed as well. Careless mages are said to have slaughtered their entire party just because they weren't careful enough when casting the spell.

Trivia

 * This spell is very useful in Ultima V to get through Dungeon Doom.
