Sign Of Sealing Greater

Level: Sorcerer/wizard 6
Casting Time: 10
Target: One door, chest,
or other opening or open
space up to 30 sq. ft./level

This spell functions like sign of sealing,
except that it can also be used to
seal an open space (such as a corridor
or an archway), creating a magical
barrier of force that repels any creature
attempting to pass. In addition, doors
and objects protected by a greater sign
of sealing are strengthened, increasing
their hardness by 10 and granting them
an extra 5 hit points per caster level.

Any object protected by a greater sign of
sealing is treated as a magic item for the
purpose of making saving throws and
gains a +4 resistance bonus on saving
throws. If its seal is broken, a greater
sign of sealing deals 1d6 points of damage
per caster level (maximum 20d6) in a
40-foot radius (Refl ex half).

A greater sign of sealing cannot be
passed with a knock spell, but it can be
dispelled (DC 15 + the caster level of
the sign’s creator). It can be disarmed
with a DC 31 Disable Device check.

Material Component: A crushed emerald
worth at least 500 gp.
