Hold Portal Open (Reversible)

(See also: Hold Portal (Wizard Spell))

Wizard's Spell Compendium

The purpose of this spell is to keep a door, gate, or valve of wood, metal, or stone from being shut. The spell only works on a portal that is already open and in range.

When the spell is cast, the door freezes in its open position. The spell can be shattered, and the door shut, by an extraplanar creature of 4 Hit Dice or more. Creatures of huge size (size H) or larger can force the door closed if they have strength and bulk comparable with their size (giants, dragons), though this is likely to break the door from its hinges unless it is specially reinforced.

The reverse of this spell, slam portal, immediately shuts an open door, gate, or valve in range. The slammed door can be opened normally. A slam portal spell cast directly against a hold portal open spell will negate it, and will close the portal if the caster is of higher level than wizard who cast the hold portal open spell.
