Earthquake

Description

You create an intense but localized and brief earthquake. The affected area becomes difficult terrain for the duration, and creatures in the area suffer a penalty on most actions (PAM and MAM) due to the violent motion.\nIn caves and tunnels, the spell causes the roof to collapse (see cavein). A similar effect applies to cliffs and other potential landslides and avalanches.\nOpen ground shakes violently and splits into multiple fissures. All grounded creatures must withstand a +5 attack against Ref (S - Fall prone). Creatures standing near a fissure (25% chance) suffer a +10 attack against Ref (S - Fall into the fissure). Creatures falling into a fissure have one round to get out before being crushed (20d6 HP damage).\nSmall bodies of water drain away into the fissures and turn into muddy ground.\nEach structure in the affected area takes 100 HP of structural damage (not reduced by DR).
