Earthquake

Choose a point on the ground that you can see within range. For the duration, an intense tremor rips through the ground in a 100-foot-radius circle centered on that point. The ground there is Difficult Terrain. When you cast this spell and at the end of each of your turns for the duration, each creature on the ground in the area makes a Dexterity saving throw. On a failed save, a creature has the Prone condition, and its Concentration is broken. You can also cause the effects below.

Fissures. A total of 1d6 fissures open in the spell’s area at the end of the turn you cast it. You choose the fissures’ locations, which can’t be under structures. Each fissure is 1d10 × 10 feet deep and 10 feet wide, and it extends from one edge of the spell’s area to another edge. A creature in the same space as a fissure must succeed on a Dexterity saving throw or fall in. A creature that successfully saves moves with the fissure’s edge as it opens.

Structures. The tremor deals 50 Bludgeoning damage to any structure in contact with the ground in the area when you cast the spell and at the end of each of your turns until the spell ends. If a structure drops to 0 Hit Points, it collapses. A creature within a distance from a collapsing structure equal to half the structure’s height makes a Dexterity saving throw. On a failed save, the creature takes 12d6 Bludgeoning damage, has the Prone condition, and is buried in the rubble, requiring a DC 20 Strength (Athletics) check as an action to escape. On a successful save, the creature takes half as much damage only.

You create a seismic disturbance at a point on the ground that you can see within range. For the duration, an intense tremor rips through the ground in a 100-foot-radius circle centered on that point and shakes creatures and structures in contact with the ground in that area. The ground in the area becomes difficult terrain. Each creature on the ground that is concentrating must make a Constitution saving throw. On a failed save, the creature’s concentration is broken. When you cast this spell and at the end of each turn you spend concentrating on it, each creature on the ground in the area must make a Dexterity saving throw. On a failed save, the creature is knocked prone. This spell can have additional effects depending on the terrain in the area, as determined by the GM.

Fissures. Fissures open throughout the spell’s area at the start of your next turn after you cast the spell. A total of 1d6 such fissures open in locations chosen by the GM. Each is 1d10 × 10 feet deep, 10 feet wide, and extends from one edge of the spell’s area to the opposite side. A creature standing on a spot where a fissure opens must succeed on a Dexterity saving throw or fall in. A creature that successfully saves moves with the fissure’s edge as it opens. A fissure that opens beneath a structure causes it to automatically collapse (see below).

Structures. The tremor deals 50 bludgeoning damage to any structure in contact with the ground in the area when you cast the spell and at the start of each of your turns until the spell ends. If a structure drops to 0 hit points, it collapses and potentially damages nearby creatures. A creature within half the distance of a structure’s height must make a Dexterity saving throw. On a failed save, the creature takes 5d6 bludgeoning damage, is knocked prone, and is buried in the rubble, requiring a DC 20 Strength (Athletics) check as an action to escape. The GM can adjust the DC higher or lower, depending on the nature of the rubble. On a successful save, the creature takes half as much damage and doesn’t fall prone or become buried.

When you cast earthquake, an intense but highly localized tremor rips the ground. The powerful shockwave created by this spell knocks creatures down, collapses structures, opens cracks in the ground, and more. The effect lasts for 1 round, during which time creatures on the ground can’t move or attack. A spellcaster on the ground must make a Concentration check (DC 20 + spell level) or lose any spell he or she tries to cast. The earthquake affects all terrain, vegetation, structures, and creatures in the area. The specific effect of an earthquake spell depends on the nature of the terrain where it is cast.

Cave, Cavern, or Tunnel: The roof collapses, dealing 8d6 points of damage to any creature caught under the cave-in (Reflex DC 15 half) and pinning that creature beneath the rubble (see below). An earthquake cast on the roof of a very large cavern could also endanger those outside the actual area but below the falling debris and rubble.

Cliffs: Earthquake causes a cliff to crumble, creating a landslide that travels horizontally as far as it falls vertically. Any creature in the path takes 8d6 points of bludgeoning damage (Reflex DC 15 half) and is pinned beneath the rubble (see below).

Open Ground: Each creature standing in the area must make a DC 15 Reflex save or fall down. Fissures open in the earth, and every creature on the ground has a 25% chance to fall into one (Reflex DC 20 to avoid a fissure). The fissures are 40 feet deep. At the end of the spell, all fissures grind shut. Treat all trapped creatures as if they were in the bury zone of an avalanche, trapped without air (see Environment for more details).

Structure: Any structure standing on open ground takes 100 points of damage, enough to collapse a typical wooden or masonry building, but not a structure built of stone or reinforced masonry. Hardness does not reduce this damage, nor is it halved as damage dealt to objects normally is. Any creature caught inside a collapsing structure takes 8d6 points of bludgeoning damage (Reflex DC 15 half) and is pinned beneath the rubble (see below).

River, Lake, or Marsh: Fissures open under the water, draining away the water from that area and forming muddy ground. Soggy marsh or swampland becomes quicksand for the duration of the spell, sucking down creatures and structures. Each creature in the area must make a DC 15 Reflex save or sink down in the mud and quicksand. At the end of the spell, the rest of the body of water rushes in to replace the drained water, possibly drowning those caught in the mud.

Pinned Beneath Rubble: Any creature pinned beneath rubble takes 1d6 points of nonlethal damage per minute while pinned. If a pinned character falls unconscious, he or she must make a DC 15 Constitution check or take 1d6 points of lethal damage each minute thereafter until freed or dead.
