This spell creates a tsunami of grass, shrubs, and trees that overgrows the
area like a tidal wave. The
plant growth creeps and curls across every-thing in the
area, ensnaring it and coiling around it as if it had been growing there for a century or more. Creatures in the
area must make a Reflex
saving throw to avoid the fast-moving growth, which otherwise deals 40d6 points of
damage from the crushing press. Buildings are engulfed and they likewise take 40d6 points of
damage. Those destroyed by the
damage have their foundations uprooted and
walls crumbled. The
plant growth is permanent. This is a ritual spell requiring fourteen other spellcasters, each of whom must contribute an unused 6th-level spell slot to the casting.
