Earthshake (Cooperative)

This spell is a weaker and more targetable form of the 7th-level priest spell earthquake. The area of effect is circular, and the priest can specifically target an area as small as a 3-foot-diameter circle up to the entire area of effect (a circle 3 feet in diameter per the caster's level) coffer the effects of an earthshake.

When this spell is cast, a very localized tremor of high strength shakes the ground. Beings standing within the area of effect must make a successful saving throw vs. spell or be thrown to the ground and stunned (unable to act) for 1d4 rounds and take 2d8 points of damage. If they succeed ac their saving throws, they are thrown to the ground and take only 1d8 points of damage.

Buildings, mine walls, and other structures take 2 points of structural damage from an earth shake spell. If a building or a targeted part of a building suffers full structural damage, it is thrown down in rubble. The average structural point value for several different types of buildings and parts of buildings is given below.

Structure | Structural Point Value ------------------------------------------+----------------------- Building, stone (small, one-story) | 30-50 Building, wooden | 8-16 Buttress | 20* Door, iron | 10 Door, wooden | 1 Door, wooden, reinforced | 3 Drawbridge | 10-15 Gate (double reinforced doors) | 8-12 Gatehouse, tone | 120 Palisade, wooden | 6-12 Portcullis | 12 Tower, round | 40-80** Tower, square | 30-50✝ Wall, curtain (per 10x10x10-foot section) | 20‡

: * All buttresses must be destroyed before what they support (a wall, a tower, etc.) takes damage. : ** For tower roughly 20 to 40 feet high and from 10 feet to 30 feet in diameter (exterior measurements), not including buttresses. : ✝ For tower roughly 20 to 40 feet high and from 10 feet to 30 feet square (exterior measurement s), not including buttresses. : ‡ This category is most often used to destroy part of a larger structure such as a castle or outer wall. To cause a section of wall to crumble, the wall must take enough structural damage to destroy it entire height, not just the bottom or top 10-foot section.

Earthshake can also be cast as a cooperative spell. If multiple priests cast this spell simultaneously on !he same area, the structural damage caused by each spell is multiplied by the number of casters participating. For example, three priest of Geb casting this spell could each inflict 6 points of structural damage (tot al 18), while four priests could each inflict 8 points of structural damage (total 32). A maximum of five Gebbite priests may cooperate in casting this spell (for a total of 50 points of structural damage in one area at once). The damage caused to beings in the area of effect is not multiplied, however, and this spell has no additional effect if cast simultaneously with an earthquake spell (or similar spell or effect).

The material components of this spell are a handful of gravel thrown to the ground and the priest's holy symbol.
