Soften Earth and Stone

When this spell is cast, all natural, undressed earth or stone in the spell's area is softened.   Wet earth becomes thick mud, dry earth becomes loose sand or dirt, and stone becomes soft clay that is easily molded or chopped.   You affect a 10-footsquare area to a depth of 1 to 4 feet, depending on the toughness or resilience of the ground at that spot (DM's option).   Magical, enchanted, dressed, or worked stone cannot be affected.   Earth or stone creatures are not affected.   A creature in mud must succeed on a Reflex save or be caught for 1d2 rounds and unable to move, attack, or cast spells.   A creature that succeeds on its save can move through the mud at half speed, and it can't run or charge.   Loose dirt is not as troublesome as mud, but all creatures in the area can move at only half their normal speed and can't run or charge over the surface.   Stone softened into clay does not hinder movement, but it does allow characters to cut, shape, or excavate areas they may not have been able to affect before.   For example, a party of adventurers trying to break out of a cavern might use this spell to soften a wall.   While soften earth and stone does not affect dressed or worked stone, cavern ceilings or vertical surfaces such as cliff faces can be affected.   Usually, this causes a moderate collapse or landslide as the loosened material peels away from the face of the wall or roof and falls.   A moderate amount of structural damage can be dealt to a manufactured structure (such as a wall or a tower) by softening the ground beneath it, causing it to settle.   However, most well-built structures will only be damaged by this spell, not destroyed.  
 

When you cast this spell, all natural, undressed earth and stone in a 10-foot square is softened, to a depth of 1 to 4 feet depending on the toughness or resilience of the ground at that spot, as determined by the DM. Wet earth becomes thick mud, dry earth becomes loose sand or dirt, and stone becomes soft clay that is easily molded or chopped. Magical, enchanted, dressed, or worked stone cannot be affected, and Earth creatures and those made from earth or stone are also unaffected.   A creature in mud must succeed on a Dexterity saving throw or be Restrained until the end of their next turn. A creature that succeeds on its saving throw can move through the mud as difficult terrain. Loose dirt is not as troublesome as mud, but is still difficult terrain. Stone softened into clay does not hinder movement, but it does allow characters to cut, shape, or excavate areas they may not have been able to affect before.   While this spell does not affect dressed or worked stone, cavern ceilings or vertical surfaces such as cliff faces can be affected. Usually, this causes a moderate collapse or landslide as the loosened material peels away from the face of the wall or roof and falls. A moderate amount of structural damage can be dealt to a manufactured structure such as a wall or tower by softening the ground beneath it, causing it to settle. However, most well-built structures will only be damaged by this spell, not destroyed.   A creature underneath falling material must make a Dexterity saving throw, taking 2d8 Bludgeoning damage for each foot of depth affected on a failure.   At Higher Levels. When you cast this spell using a higher level spell slot, you can affect one additional 10-foot Square for each slot level above its base level. Each of these squares must be touching another on at least one side.
