Keep Cleave
(Invocation)
(Dimension)
Level: 8
Range: 700 yds.
Components: V, S, M
Casting Time: 1 rd.
Duration: Permanent
Area of Effect: Special
Saving Throw: None
This spell causes a large rift or fissure to open up by the caster invoking a dimensional shift of sorts. This will cause any one surface of a keep, other fortification, or dwelling place to split and open up. This spell will also do the same thing to all other barriers, magical or otherwise, that are 8th-level or lower. The rift, or opening produced by this spell can be up to a 1-foot in height and twice that distance in width. Thus a 16th-level caster could create a vertical slash (or cleave) in a keep or castle that is up to 16 feet high and 32 feet wide.
The shape of the cleave in the structure is shaped like a cut, being the widest in the center and tapering off at the top and bottom to only a foot wide, before closing down to a point no more than an inch in width. Magical structures receive a saving throw vs. disintegration with any applicable bonuses to avoid being breached in this way.
The material component for keep cleave is a claw from a praying mantis and a piece of stone or any other harder substance that keeps are made from.
Notes: Uncommon spell.
